I really wish I could have studied paleontology. I grew up in a rough area , and labor is all I can do . But I know dinosaurs have been my love all my life .
After not doing much with my life I recently made the decision to go back to school in order to learn paleontology. It was my dream as a child, and now at 26 I know it's what I need to do. I'm using Kahn academy online to relearn everything from math to chemistry to biology, as well as some courses on Coursera. Once I get myself to a college level, I'm gonna try doing SNHU online. In short, if that is your dream, pursue it! It's never too late to make your life unimaginably better! I'll be rooting for you if you take the leap
As a 25 year old about to be married and with a child, I have sat down for a long time and decided if I wanted to go back to school and pursue my dream as a geologist and paleontologist and I’ve finally decided to chase my dream, I’m looking to hopefully in the next couple years obtain my associates and bachelors and work at the Fernbank museum in Atlanta Georgia and also volunteer while attending college to get as much experience as possible. In the future I hope to fully push for a masters and PhD
"Was T-Rex a scavenger?" Actually, that is a strange question, since most animals are opportunistic feeders. It would be very unwise, for any animal, to leave good food behind and only hunt live animals. Most, if not all animals, will eat the food, when it is presented to them, without having to hunt or search for it. T-Rex is big, fast, has a huge mouth, a tremendous bite force, excellent smell and 3D vision. Sounds like a hunter to me. Scavenging is just another method to get food.
telescopereplicator agreed, most animals are smart enough to know not to risk getting injured and perhaps dying chasing down a moving,panicking sometimes bigger animal. They will settle for a carcass even if it is a few days old because they know the risk every time they get into hunt mode.
along with its massive bite force, it can eat the bones due to being able to shatter them and pretty much get all the vitamins and minerals, so the T-rex is very much an opportunistic, be it hunting or scavenging, it was good at both.
I'm so glad the algorithm randomly recommended this video to me in 2021! This presentation was absolutely fantastic, thanks for sharing so much knowledge. Much love from Brazil :)
Not sure why this suddenly popped up in my recommended two years after being posted, but I'm glad it did! What a great presentation. Great speaker, and really well-done editing that kept it engaging the whole time. The hour flew by. Subbed, and a bit annoyed that RUclips hasn't recommended this channel to me until now. I've watched and am subbed to quite a few science-based channels.
Right, not only did he know the material intimately but he communicated it about as well as any documentary narrator I can think of so that the layperson could grasp it.

@@EricFarmer01 Oh really? Maybe you are the hoax as humans have only been around for a slice of time compared to the 100 Million years that the dinosaurs were.
This is a stunning presentation. David Hone's passion for the subject translates beautifully into the way he presents this lecture. Absolute fantastic. Thank You, David.
When I was 10 years old, my dino mania began. This was some 15 years before Jurassic Park. My favourite to be the Allosaur. These animals have always kept on amazing me. Great talk. Thanks
Did you know that T-Rexes are closer in time to humans than they are to Allosaurs? Allosaurs lived between 155 to 145 million years ago, T-Rex between 68 to 65 million years ago. In other words, they are at minimum 77 million years apart in time, while humans and T-Rexes are at minimum 65 million years apart. Allosaur bones were long fossilized rock when T-Rex first appeared.
38:34 The explanation of the upper teeth stripping flesh from bone and how those , relatively small teeth on a huge animal worked was so well explained..... Kudos.
I HAVE BEEN FACINATED WITH DINOS FOR MY ENTIRE LIFE I`M 78 NOW THIS IS THE BEST PRESENTATION I HAVE EVER SEEN THANK YOU FOR INFORMING US ON THE TRUE ASPECTS OF DINOS.
Initially I was searching for CGI’s of Dinosaurs when I came across this. My first thought was “Oh a (long) lecture” but like many RI lectures it pulled me in. David Hone provided an informative & entertaining talk on Tyrannosaurs & was engaging with his well researched talk. Give it a viewing. You’re unlikely to regret it.
Excellent talk. Think of just how tense the nights would be knowing this super-predator was out there. Its gaze focusing on you would be the most terrifying thing to see, because at that moment it knows you spotted it, and it will now be coming at you at full tilt. You cannot outrun it, you cannot outfight it, and you will not be able to hide. You have to get underground or underwater in the next few seconds or you are dead.
One of my favorite lecture of all time. Really drills down into what makes Tyrannosaurs some of the greatest dinosaurs to ever live. And although this is 3 years old at the point of posting this, but there is something currently disputed about it. Current consensus of feathers on Tyrannosaurus is that it's probably the case that juvenile Tyrannosaurus would have had an insulating coat of feathers, but it would have lost them partially or entirely over time. Although skin impressions of Tyrannosaurus have been rare and their coverage small, all of the impressions have been scaly. There has been bits of skin all over the head and small patches on the neck, the hips, the tail, and even the feet of adult Tyrannosaurus but each impression showed scales. There has been very little coverage as a whole, but the spread of scales across the body argue that rather than putting feathers where they aren't based on their ancestors, it would be more appropriate to assume the entirety of Tyrannosaurus was scaly. I love feathered Tyrannosaurs, with Nanuqsaurus being a favorite of mine. It was an Alaskan Tyrannosaur entirely covered in feathers; but the science supports a scaly Tyrannosaurus. Also, it's likely Tyrannosaurus has an incredible sense of smell, maybe one of the best of any animal. They possessed olfactory bulbs the size of grapefruit, which high estimates show it could have smelled carcasses up to 40 km away with the acuity of 100 bloodhounds. But that is still not proven. Regardless, it had the best sense of smell of any known dinosaur. Additionally, measurements of their brain case show an incredibly large brain relative to their enormous size and suggest intelligence comparable to a chimpanzee. Intelligence in animals can be generalize by brain to body size, as the bigger the body the more brain needs to be used to maintain and control it. Tyrannosaurus has a brain bigger than our own, albeit in a body 100x more massive. But considering the lack of brains of other dinosaurs, that is still impressive. Those would've been a good talking point in the lecture I would think. Tyrannosaurus wasn't just a brute of unrivaled strength and size, but was surprisingly keen in senses and brainy compared to just about any other large dinosaur.
Just depends on the temperature at the time I agree the younger ones would be more likely to have the feathers maybe even the older ones in some spots feathers seem to be good insulation the birds can handle the winter around it seems without a problem.
Also important to keep in mind that modern avians (descendants of the big theropods) have extremely densely packed neurons. They’re typically much smarter than one would expect given their brain-to-body-size ratio.
There are a few teachers that can present information quite well. The keys as re 1. The teacher knows and understands the information well and therefore can present it in an understandable msnner.2. The teacher likes and is enthusiastic about the subject. This enthusiasm is contagious to the student. 3. The teacher demonstrates to the student why and how the information being presented is relevant to the student. I remember in undergrad school a teacher who taught accounting and oddly enough economic geography. That was in the late 60s. I was an accounting major and wondered how and why this wasca required subject. I was prepared to be bored out of my mind. After all I was a n accounting major. However the subject turned out to be fascinating. Want to know why the USXbecame a major regional and then world power? A MAJOR set of reasons lie in its position in the world I ts extensive navigable river system especially the Mississippi the coastlines providing deep water ports on 3 sides along with extensive iron ore and coal deposits along with huge easily accessed oil and gas deposits . And so forth. 10 years later I find I'm advising a major corporation. On where to select large tracts of land for development. This guy could lecture well on any subject he knows and liked
just shows when a dr of some particular subject, expounds on the subject he or she loves, you get that dynamic understanding beyond academic understanding, but an illumination, of deeper thinking we humans are capable of. some expound on uninteresting subjects, but in this case, very enlightening. thank you sir for understanding our condition.
Simply amazing! This is ,for my view, the best lecture about an animal that has fashionated me all my life. I am 71 years old. thank you so much, I not only enjoyed it, I loved it!
fluffy death cruising at 25-30 mph. Us mammals should worship that asteriod for ending the dinosaurian arms race because we would of never had a chance
@@c.rutherford I think it is their way of challenging Christian theories about evolution. Kind of strange. I just don't buy it and it has nothing to do with Religion. Just sounds kind of wrong. I've never seen a Croc with feathers?
@@constantine7382 it seems the "Birds are Dinosaurs!" sacred mantra of Paleo fans has gone way overboard to me. Yes birds evolved from an offshoot branch of surviving Theropods, true. But that does not by any means guarantee that every dinosaur looked like a scaled up pigeon. I mean a mouse and an elephant are both mammals, but an elephant doesn't look like a giant version of a mouse, right? And the other thing that kinda annoys me is they will go on about birds surviving BECAUSE they had feathers, unlike the rest..... but then go right on depicting all the "non-avian dinosaurs" as having them anyway. Ebhbrbrbrrrrr.
That was really enjoyable and fascinating, I've just bought his book, "the Tyrannosaur chronicles" I'm absolutely fascinated by these things and have been all my life and I'm 57yrs old now! I love how it's all becoming clearer bit by bit how these magnificent animals lived and behaved, thank you David 👍
Thank you for the talk, sir. This was a lot of fun and supplied a lot of tasty crunchy food for my imagination. When I was a kid, I used to adore scaly scary dinosaurs, but I could never actually imagine them living, breathing, hunting and roaming in the wild. Your talk provided a glimpse into that. Thank you very much, once again.
Thank you for really interesting and engaging lecture! Your passion and enthusiasm is contagious. It would have been great to see the lecture live, but i'll take this!
This was great!! This guy, David Hone, is a wonderful speaker and really held my attention throughout the entire video! I only planned on watching snippets of this, but once it started, I felt compelled to watch and listen to every minute of it! What an interesting video!!
@@wilsonhuber Besides trillions upon trillions of stars and even galaxies there are umpteen many time more planets with at least a few million likely harboring life. And when was the last time you had a look to say for sure there's nothing out there?
As someone who can't afford to go to school for paleontology and I didn't do so hot in high school, I absolutely loved this! Videos like this help educate those of us who can't get a hold of it otherwise. Kept my interest the whole time and I learned a lot. Tyrannosaurus Rex has always been my favorite dinosaur and boy did this give me a lot of info! Honestly surprised he didn't touch on sense of smell? Amazing educational video though thank you for sharing!
Mr.Hone, I just finished reading your marvelous book The Tyrannosaur Chronicles, a few days ago. Thoroughly enjoyed it and found it truly edifying. Thank you.
David, I listened to your book on audible and I LOVED IT!! I hope to one day listen to one of your seminars and meet you in person. Thank you for your love and passion for your work!
An excellent lecture on the T Rex. I learned nothing i didn't already know, but it's never a bad thing wasting an hour hearing about T REX. An incredible animal
For anyone who doesn't know, the main guy who was making the "T Rex were scavengers" argument also openly disliked T Rex. The reason being that his favorite dinosaur was actually the american iguanadon (I think it has a different name now, but I forget it), but when he went out on expeditions to find it, he couldn't find any, and he just *kept finding T Rex fossils.* So he got a little petty and started using his doctorate to push the idea that T Rex was a big ugly lazy scavenger, despite the fact that he doesn't study the animal.
Jack Horner was looking for duckbills like edmontosaurus yeah. It's honestly so petty to try to defame an extinct animal because it got the preservation bias card
These big fellows are so popular, it almost feels like people try to knock them down a peg sometimes. "They were so big and slow!" "They were stupid!" "They never hunted live prey!" "They were practically blind!" and on, and on... This lecture, among several others on youtube alone, prove all of that wrong. I know it's cool to hate what's mainstream. But these big freakin' animals are so much more than their street cred of cool alone could ever bring. You gotta give it up for the king.
I find it interesting that alkost every lecture on these animals on youtube gives a completely different idea about what they are ( hunters or scavengers, or mixed) and how fast they were. Some say very slow because of some feet impressions and weight of then some say very fast due to bone structure. I am not sure what to believe but I am fascinated anyway...Thank you for all this amazing work!
What a great presentation. Its amazing what happens when science crosses paths with biology, and what information can be extracted in the process. I'm more informed now than I was an hour ago. Thank you so much for the education. Hats off to you sir
I noticed he still says that even after a t-rex tooth was found in a prey dinosaur. news.nationalgeographic.com/news/2013/07/130715-tyrannosaurus-rex-predator-duckbill-dinosaurs-paleontology-science/ www.theguardian.com/science/2013/jul/15/t-rex-tooth-embedded-prey-dinosaur Seems likely that T-rex would have went after the easiest meal possible including scavenging and killing younger dinosaurs.
Sometimes I wonder though, if Horner hadn't been so persistent with his T-Rex claims, would others have gathered the wealth of evidence that has disproved them?
probably. T.rex is one of those animals that we know more of than most living animals because its such a inspiring creature. There is a drive to outdo each other in new discoveries about the T.rex
@@WaterShowsProd Maybe, depends on when the evidence was found, some of them might have been found before Horner started saying that T. rex was a scavenger. Regardless, even if Horner hadn't been so persistent, paleontologists would have still found the evidence that they have but wouldn't have given it a second thought since without Horner and T. rex was a scavenger, there would be no debate since there are very few land dwelling obligate scavengers and none are very large. As mentioned in this video, most carnivores are equal opportunists, they hunt when necessary but are not above a free meal or, in the case of lions, an easy meal from chasing off a smaller predator from theirs.
The ancestors were more like leopards, possibly the larger, bigger descendants had a dietary pattern closer to a hyena? What if they were specialists, but over time they could stomach a level of decay? Like as if we contrast finicky cats to dogs?
Man this came up randomly as a playing next just as i just happened to start playing Path of Titans 2 days ago and I had no idea we knew so much about the T Rex and dinosaurs in general. Great video.
Bought the book after watching this. I still wonder: why is the conclusion about T-Rex being active predator + scavenger just now a reasonable one instead of all the time before? Or is it just the media platform used? Videos here on YT seem to either propose one or the other possibility but never both. The signs were all there. Why is the interpretation of all the fossils so different compared to years ago? Paleontolgy is so fascinating. You show the same data to 5 different people and you'll get 5 different interpretations.
Some more extreme paleontologists have very negative views towards the media and the public's understanding of dinosaurs. This is mostly understandable as popular movies and even many documentaries greatly misrepresent dinosaurs. I think its for this reason, some jumped on the 't-rex is a scavenger' bandwagon in an effort to dethrone the most famous dinosaur as a predator, and prove to the public they were all wrong about the dinosaur they loved. While t-rex does have some adaptations which are similar to pure scavenging (bone crushing bite, great sense of smell), these are not exclusive to scavengers by any means (crocodiles are predators with both these traits). I think most reasonable paleontologists realised that T-rex couldn't have been exclusively a scavenger.
@@TheRamiRocketMan I think its a misunderstanding that got out of hand. Usually when news gets a hold of a paper they don't actually read it and just make sweeping claims that everyone reads and no one ever bothers to go looking for the original source. At the time there was a theory Tyrannosaurus scavenged long dead carcasses as opposed to hunting live prey or scavenging fresh carcasses. It would have certainly hunted and scavenged fresh kills but its debatable whether it ate long dead carrion.
Sir! This is brilliant! I love the T-Rex ever since I saw the skull in the American Museum of Natural History in New York 1967. I was 8 years old. Still have the small T-Rex metal die cast model my mother bought for me there. Thanks for "restoring" my Rexie as the king! I am from Sweden.
I am just 2 years older than you and lived in New York City all but one year of my life. I too have been fascinated with dinosaurs ever since my mother first brought me there. Went there on a class trip once too. We were asked to write a report on the trip and I, for some reason, included a report on the lunch my mom packed for me that day, writing that the meatball sandwich was good but "mushy". Lol! I was about 7 or 8 I guess.
I saw a t-rex skeleton about that same age, albeit in sweden(hälsningar från Norrland) and it always fascinated me and does so even as an adult, truly a majestic beast!
I'm working as student for an university work on evolution of illustration into paleontology, and thanks to this video, I have more clues now. Thanks a lot, that was very interesting
T-Rex could not have been very happy about evolving out of his arms. "Son, your great great grandafather was able to scratch his own belly. I'm not sure what happened over the past few generations, but these stupid sorry excuses for arms are worthless!"
Thank you sir, for providing your viewers with a very fine lecture. Without doubt, the best that I have ever had the pleasure to learn so much from. Excellent.
This is the best video I have ever seen. The shear power of this animal if mind blowing. Speed, strength, vision everything you need to create an apex predator. I love this creature 10 times as much as I did.
":...a very selective feeder..." That means it was NOT a scavenger primarily. Now, like any apex predator, like a lion, it might steal a kill from a smaller predator, but that is not scavenging. I believe scavengers would not be such picky eaters - they will eat whatever is left. Also, if it was primarily a scavenger -- what would it need speed for? Why would it need great eyes?? No, I think it was a hunter. Moreover, it was a hunter that ran its prey to ground, that is, NOT an ambush predator. More like wolves, than a cat.
This has been a real treat to watch. I'm one of those dinosaur nerds who love videos like this. Without trying to sound like a know-it-all, there was a recent study that said that having studied fossilized skin impressions, T-Rex did not have feathers.
Great lecture! Another corker discovery on the RI channel! :D ....I love how with his sleeves rolled up and keeping his elbows at his side as he gesticulates, he occasionally kinda comes off as 'a bit T-Rex' himself XD
Bravo Dr. Hone, and very informative lecture. Like the gentleman below, I'm surprised that this has only popped up until now, seeing as I've subbed to TED Talks since I first went to uni (studying marine biology & coastal ecology), and I watch loads of The Isle vids. As a child (started with my dinosaurs at 2 years), after I got over the 'I want to be a spaceman and an animator', and just before I got the marine biology bug from Jacques Custeau, I actually wanted to study paleontology. I've been to the Natural History Museum more times than I can remember, I've stood between displays comparing anatomy/physiology, and the mind wonders of who they looked, behaved and sounded. However, I'm very impressed by the depth of knowledge and pace of this lecture. I would've loved to have been in the audience for this. Subbed!

Pretty much
Yes options give opportunities, Burger King or McDonald's. Wendy's or KFC all are on my hunting agenda as I stalk the mean streets looking for prey.🦂
Scavenging would require a great sense of smell, like bears. Bear skulls have lots of area devoted to smell. Not so much in a tyrannosaur.
along with its massive bite force, it can eat the bones due to being able to shatter them and pretty much get all the vitamins and minerals, so the T-rex is very much an opportunistic, be it hunting or scavenging, it was good at both.
Putting a giant Tyrannosaur head in front of you facing the audience while doing your lecture is quite a power move :P

More of David Hone, please! Could listen to him lecture for hours…
I watch hundreds of YT vids about science, space and tech... This is the most fascinating vid I've seen in years!
Why cant teachers do this?
I watched for an hour and it felt like no time had passed!
Very enjoyable and very informitive.
Right? I could've gone another hour easily.
There are a few teachers that can present information quite well.
The keys as re 1. The teacher knows and understands the information well and therefore can present it in an understandable msnner.2.
The teacher likes and is enthusiastic about the subject. This enthusiasm is contagious to the student. 3.
The teacher demonstrates to the student why and how the information being presented is relevant to the student.
I remember in undergrad school a teacher who taught accounting and oddly enough economic geography.
That was in the late 60s.
I was an accounting major and wondered how and why this wasca required subject.
I was prepared to be bored out of my mind.
After all I was a n accounting major.
However the subject turned out to be fascinating.
Want to know why the USXbecame a major regional and then world power?
A MAJOR set of reasons lie in its position in the world I ts extensive navigable river system especially the Mississippi the coastlines providing deep water ports on 3 sides along with extensive iron ore and coal deposits along with huge easily accessed oil and gas deposits .
And so forth.
10 years later I find I'm advising a major corporation. On where to select large tracts of land for development.
This guy could lecture well on any subject he knows and liked
That was the fastest hour long presentation I've literally ever heard. I want more.
Then you should listen to the podcast Dave does with comedian Iszi Lawrence called "Terrible Lizards"
just shows when a dr of some particular subject, expounds on the subject he or she loves, you get that dynamic understanding beyond academic understanding, but an illumination, of deeper thinking we humans are capable of. some expound on uninteresting subjects, but in this case, very enlightening. thank you sir for understanding our condition.
You could have explained that in a much simpler way
@@dylankramer9294 It is a simpler way.
Simply amazing! This is ,for my view, the best lecture about an animal that has fashionated me all my life. I am 71 years old. thank you so much, I not only enjoyed it, I loved it!
Really enjoyed that. Dr Hone has the knack of making a subject really interesting and totally engrossing.
I always loved dinosaurs as a kid, and I was definitely one of the ones who were taken by "T-Rex obsession".
Then I would recommend the new Jurassic Park game on PC.
Eddy M which game
Jurassic World Evolution
Eddy M 👍
@@EddyMakes Yes it's very cool if you like dinosaurs.
Thank you very much for making this aavailable to everyone involved!
Definitely one of the best lectures I've ever listened to , absolutely fascinating , keep up the good work ,thank you so much !
My inner child was grinning ear to ear for this talk. Great talk!
This was INSANELY good. Makes you want to learn more about them as well which is great
A great illumination of how life drove evolution. Not just physical environment, but biological environment.
"perhaps not a giant chicken, but certainly fluffy"
-David Hone, describing a tyrannosaurus
fluffy death cruising at 25-30 mph. Us mammals should worship that asteriod for ending the dinosaurian arms race because we would of never had a chance
I’ve heard a lot of recent theories that it actually didn’t have feathers but that a lot of smaller predatory dinosaurs still probably did
Why is everyone obsessed with turning T-Rex into a giant fluffy adorable chick lol
@@c.rutherford I think it is their way of challenging Christian theories about evolution. Kind of strange. I just don't buy it and it has nothing to do with Religion. Just sounds kind of wrong. I've never seen a Croc with feathers?
@@constantine7382 it seems the "Birds are Dinosaurs!" sacred mantra of Paleo fans has gone way overboard to me.
Yes birds evolved from an offshoot branch of surviving Theropods, true. But that does not by any means guarantee that every dinosaur looked like a scaled up pigeon.
I mean a mouse and an elephant are both mammals, but an elephant doesn't look like a giant version of a mouse, right?
And the other thing that kinda annoys me is they will go on about birds surviving BECAUSE they had feathers, unlike the rest..... but then go right on depicting all the "non-avian dinosaurs" as having them anyway. Ebhbrbrbrrrrr.
Great lecture! I have been a dino lover since childhood, and I will never lose my fascination with them 🦖
That was really enjoyable and fascinating, I've just bought his book, "the Tyrannosaur chronicles" I'm absolutely fascinated by these things and have been all my life and I'm 57yrs old now! I love how it's all becoming clearer bit by bit how these magnificent animals lived and behaved, thank you David 👍
Never to old for dinos
I've been in love with Dinosaurs since I was a 4 year old girl.
This talk was wonderful! It made my inner child happy.
Neats!
I'd be chuffed to walk my pet Velociraptor but being a responsible dinorider I'd be carrying garbage bags to pick up Dino poo off your front lawn.
That was a fantastic video. Very informative and I love the different camera angles. It had my attention throughout the entire duration.
This video on Tyrannosaurus will spawn even more research on the specimens :D Thank you for the talk.
Thank you for the talk, sir. This was a lot of fun and supplied a lot of tasty crunchy food for my imagination. When I was a kid, I used to adore scaly scary dinosaurs, but I could never actually imagine them living, breathing, hunting and roaming in the wild. Your talk provided a glimpse into that. Thank you very much, once again.
Thank you for really interesting and engaging lecture! Your passion and enthusiasm is contagious. It would have been great to see the lecture live, but i'll take this!
This was great!! This guy, David Hone, is a wonderful speaker and really held my attention throughout the entire video! I only planned on watching snippets of this, but once it started, I felt compelled to watch and listen to every minute of it! What an interesting video!!
So mind boggling that these things existed. Makes one wonder what else exists in our universe.
There's absolutely Nothing out there and we're wasting our time trying to explore space !
@@wilsonhuber funny troll
@@wilsonhuber Besides trillions upon trillions of stars and even galaxies there are umpteen many time more planets with at least a few million likely harboring life. And when was the last time you had a look to say for sure there's nothing out there?
Good point. Wilson Huber is an idiot troll.
Cringe
As someone who can't afford to go to school for paleontology and I didn't do so hot in high school, I absolutely loved this! Videos like this help educate those of us who can't get a hold of it otherwise. Kept my interest the whole time and I learned a lot. Tyrannosaurus Rex has always been my favorite dinosaur and boy did this give me a lot of info! Honestly surprised he didn't touch on sense of smell? Amazing educational video though thank you for sharing!
Fascinating lecture! That hour just whizzed by. Learned a few more things about Tyrannosaurs, and Dr. Hone is a fantastic speaker!
this is the type of presenter that makes you want to listen and learn. really enjoy his style
Incredible presentation, blew through nearly an hour, this guy is a great speaker.
Thank you for sharing this knowledge David Hone. What an awesome presentation.
Fascinating from beginning to end. A truly wonderful lecture!
This is the ultimate Tyrannosaur lecture.
I was interested in this lecture the entire time I can’t even believe I was watching this for an hour completely engaged
Mr.Hone, I just finished reading your marvelous book The Tyrannosaur Chronicles, a few days ago. Thoroughly enjoyed it and found it truly edifying. Thank you.
David, I listened to your book on audible and I LOVED IT!! I hope to one day listen to one of your seminars and meet you in person. Thank you for your love and passion for your work!
This paleontologist is a phenomenal speaker.
An excellent lecture on the T Rex. I learned nothing i didn't already know, but it's never a bad thing wasting an hour hearing about T REX. An incredible animal
For anyone who doesn't know, the main guy who was making the "T Rex were scavengers" argument also openly disliked T Rex. The reason being that his favorite dinosaur was actually the american iguanadon (I think it has a different name now, but I forget it), but when he went out on expeditions to find it, he couldn't find any, and he just *kept finding T Rex fossils.* So he got a little petty and started using his doctorate to push the idea that T Rex was a big ugly lazy scavenger, despite the fact that he doesn't study the animal.
Was the dinosaur a Maiasaura? =P
Jack Horner was looking for duckbills like edmontosaurus yeah. It's honestly so petty to try to defame an extinct animal because it got the preservation bias card
Well it's all guess work either way. You can't know how they behaved just by looking at their bones.
@@lc-ii9iiunless someone invents a time machine
@@lc-ii9ii You commented on a video that explains pretty much how we can understand how animal behaved thanks to their bones and how we find them.
This is a first-class video. The presenter is both very knowledgeable and a compelling speaker, which is a rare combination.
An excellent presentation. His style, and delivery is engaging. Not dry and monotonous like many.
I prefer a nice warm pizza but if I come across old pizza sitting in the break room, I’ll eat it.
These big fellows are so popular, it almost feels like people try to knock them down a peg sometimes. "They were so big and slow!" "They were stupid!" "They never hunted live prey!" "They were practically blind!" and on, and on... This lecture, among several others on youtube alone, prove all of that wrong. I know it's cool to hate what's mainstream. But these big freakin' animals are so much more than their street cred of cool alone could ever bring. You gotta give it up for the king.
This was an absolutely fascinating talk. I learnt a lot. Thank you for uploading this! I have just purchased the book shown at the end to learn more.
Most fair and accurate presentation about dinosaurs I have heard yet.
This is a superb presentation! Enjoyed every moment of it!
Excellent presentation! I learned a huge amount and enjoyed every minute of it. Thank you!
I find it interesting that alkost every lecture on these animals on youtube gives a completely different idea about what they are ( hunters or scavengers, or mixed) and how fast they were. Some say very slow because of some feet impressions and weight of then some say very fast due to bone structure. I am not sure what to believe but I am fascinated anyway...Thank you for all this amazing work!
There are very few slow predators. Lots of slow herbavoirs.
I don't think Tyrannosaurus needs to be fast in general, just faster than it's prey (Triceratops, Edmontosaurus maybe Ankylosaurus)
rewatched this so many times. great lecture, and fascinating topic. thanks dr hone :)
I can listen to this all day, please do or upload more. Thanks
What a great presentation. Its amazing what happens when science crosses paths with biology, and what information can be extracted in the process. I'm more informed now than I was an hour ago. Thank you so much for the education. Hats off to you sir
Im confused. Biology is science. How does it “cross paths”?
@@tanyanguyen3704 lol was going to say this
and somewhere i can hear jack horner say " it was a scavenger"
I noticed he still says that even after a t-rex tooth was found in a prey dinosaur. news.nationalgeographic.com/news/2013/07/130715-tyrannosaurus-rex-predator-duckbill-dinosaurs-paleontology-science/ www.theguardian.com/science/2013/jul/15/t-rex-tooth-embedded-prey-dinosaur Seems likely that T-rex would have went after the easiest meal possible including scavenging and killing younger dinosaurs.
Sometimes I wonder though, if Horner hadn't been so persistent with his T-Rex claims, would others have gathered the wealth of evidence that has disproved them?
probably. T.rex is one of those animals that we know more of than most living animals because its such a inspiring creature. There is a drive to outdo each other in new discoveries about the T.rex
@@WaterShowsProd Maybe, depends on when the evidence was found, some of them might have been found before Horner started saying that T. rex was a scavenger. Regardless, even if Horner hadn't been so persistent, paleontologists would have still found the evidence that they have but wouldn't have given it a second thought since without Horner and T. rex was a scavenger, there would be no debate since there are very few land dwelling obligate scavengers and none are very large. As mentioned in this video, most carnivores are equal opportunists, they hunt when necessary but are not above a free meal or, in the case of lions, an easy meal from chasing off a smaller predator from theirs.
The ancestors were more like leopards, possibly the larger, bigger descendants had a dietary pattern closer to a hyena? What if they were specialists, but over time they could stomach a level of decay? Like as if we contrast finicky cats to dogs?
Amazing lecture
I watched this a long time ago then it popped back up in my recommended videos today!
Best presentation on Tyrannosaurus I've ever heard! Such details!
Man this came up randomly as a playing next just as i just happened to start playing Path of Titans 2 days ago and I had no idea we knew so much about the T Rex and dinosaurs in general. Great video.
What a great lecture.
Excellent talk and kudos for not "dumbing it down" for the very young audience.
Bought the book after watching this.
I still wonder: why is the conclusion about T-Rex being active predator + scavenger just now a reasonable one instead of all the time before? Or is it just the media platform used? Videos here on YT seem to either propose one or the other possibility but never both. The signs were all there. Why is the interpretation of all the fossils so different compared to years ago?
Paleontolgy is so fascinating. You show the same data to 5 different people and you'll get 5 different interpretations.
Some more extreme paleontologists have very negative views towards the media and the public's understanding of dinosaurs. This is mostly understandable as popular movies and even many documentaries greatly misrepresent dinosaurs. I think its for this reason, some jumped on the 't-rex is a scavenger' bandwagon in an effort to dethrone the most famous dinosaur as a predator, and prove to the public they were all wrong about the dinosaur they loved. While t-rex does have some adaptations which are similar to pure scavenging (bone crushing bite, great sense of smell), these are not exclusive to scavengers by any means (crocodiles are predators with both these traits).
I think most reasonable paleontologists realised that T-rex couldn't have been exclusively a scavenger.
@@TheRamiRocketMan T. rex. "I think it's for this reason..."
@@TheRamiRocketMan I think its a misunderstanding that got out of hand. Usually when news gets a hold of a paper they don't actually read it and just make sweeping claims that everyone reads and no one ever bothers to go looking for the original source. At the time there was a theory Tyrannosaurus scavenged long dead carcasses as opposed to hunting live prey or scavenging fresh carcasses. It would have certainly hunted and scavenged fresh kills but its debatable whether it ate long dead carrion.
Fascinating. Thank you RI and Dr Hone.
Great presentation. I was just trying to throw something on in the background and ended up sitting and watching the entire thing.
Watching this made me buy Dr Hone's book. Its a fantastic read.
Aren't just the characteristics of good eye sight and fast long distance running indicative of predation as the major source of food?
Sir! This is brilliant! I love the T-Rex ever since I saw the skull in the American Museum of Natural History in New York 1967. I was 8 years old. Still have the small T-Rex metal die cast model my mother bought for me there.
Thanks for "restoring" my Rexie as the king! I am from Sweden.
I am just 2 years older than you and lived in New York City all but one year of my life. I too have been fascinated with dinosaurs ever since my mother first brought me there. Went there on a class trip once too. We were asked to write a report on the trip and I, for some reason, included a report on the lunch my mom packed for me that day, writing that the meatball sandwich was good but "mushy". Lol! I was about 7 or 8 I guess.
I saw a t-rex skeleton about that same age, albeit in sweden(hälsningar från Norrland) and it always fascinated me and does so even as an adult, truly a majestic beast!
@@dennisnordlund902 God Jul!!!
I'm working as student for an university work on evolution of illustration into paleontology, and thanks to this video, I have more clues now.
Thanks a lot, that was very interesting
Great speaker, great teacher. Top notch.
T-Rex could not have been very happy about evolving out of his arms. "Son, your great great grandafather was able to scratch his own belly. I'm not sure what happened over the past few generations, but these stupid sorry excuses for arms are worthless!"
I went to Chicago just to see SUE. Impressive. Also items fromKing Tut's tomb (but that's another lecture!).
Thank you sir, for providing your viewers with a very fine lecture. Without doubt, the best that I have ever had the pleasure to learn so much from. Excellent.
This was incredibly enjoyable.
I love this video, got damit. Still watch it on loop sometimes.
Thank you so much for this lecture it was very informative
This is the best video I have ever seen. The shear power of this animal if mind blowing. Speed, strength, vision everything you need to create an apex predator. I love this creature 10 times as much as I did.
Glad you enjoyed it
@@TheRoyalInstitution I really did
":...a very selective feeder..." That means it was NOT a scavenger primarily. Now, like any apex predator, like a lion, it might steal a kill from a smaller predator, but that is not scavenging. I believe scavengers would not be such picky eaters - they will eat whatever is left.
Also, if it was primarily a scavenger -- what would it need speed for? Why would it need great eyes?? No, I think it was a hunter. Moreover, it was a hunter that ran its prey to ground, that is, NOT an ambush predator. More like wolves, than a cat.
Selective in what parts of the animal it ate, as stated in the part of the lecture where he presented the evidence of scavenging.
This is the best Trex lecture I've ever heard
Many thanks. Wonderful presentation.
This has been a real treat to watch. I'm one of those dinosaur nerds who love videos like this. Without trying to sound like a know-it-all, there was a recent study that said that having studied fossilized skin impressions, T-Rex did not have feathers.
It would have been great if he discussed whether Tyrannosaurs lived solitary lives or in family groups.
He did actually speak about social dinosaurs in another talk he gave here - ruclips.net/video/7kxRaVTVNjk/видео.html
Great lecture! Another corker discovery on the RI channel! :D
....I love how with his sleeves rolled up and keeping his elbows at his side as he gesticulates,
he occasionally kinda comes off as 'a bit T-Rex' himself XD
Bravo Dr. Hone, and very informative lecture. Like the gentleman below, I'm surprised that this has only popped up until now, seeing as I've subbed to TED Talks since I first went to uni (studying marine biology & coastal ecology), and I watch loads of The Isle vids. As a child (started with my dinosaurs at 2 years), after I got over the 'I want to be a spaceman and an animator', and just before I got the marine biology bug from Jacques Custeau, I actually wanted to study paleontology. I've been to the Natural History Museum more times than I can remember, I've stood between displays comparing anatomy/physiology, and the mind wonders of who they looked, behaved and sounded. However, I'm very impressed by the depth of knowledge and pace of this lecture. I would've loved to have been in the audience for this. Subbed!
Wow. Fascinating. I LOVE hearing the real deal from experts in just about any field but this was cool. Loved it. Thank you
