I've been learning about dinosaurs for almost 70 years. I've always kept an open mind to new discoveries. These days I live in Florida and we have alligator & Crocodiles. I also drive for Uber. You can't imagine the number of passengers who will ask about them. Before long the conversation will turn into a history/paleontology lesson. Especially when I was driving in Cleveland. It was the best part of driving for Uber. I often wonder why I didn't major in the subject in college. Probably would have been a lot happier today.
Curved surfaces are good for transferring energy. Base Ball Bats, Golf Drivers. And round hard football Helmets were used as weapons until butting with your helmet was outlawed.
"Politics or Law", where the truth is treated as subversive and against the ruling narrative. Paleontology is the the most re-creative of human sciences other than Mathematics, that is all there is.
Bone rings and tree rings do not always equate to years but can in a large number of cases be an indicator of more than one growing season per annum and thinner rings may denote a bad year or season. The teeth of T Rex May denote that it ate both meat and plant matter as most birds do today if given the chance. The spaces between the teeth are of a size that would be perfect for tearing off large chunks of flesh or stripping foliage off large plants. It may be a good idea to put the word out to look for groupings of stones or pebbles when digging up bones as most birds and some reptiles use a gizzard to grind what they eat. The neck of T Rex dose not look it has the agility to reach what it holds down under its feet, but may have the strength to shake its meal into small pieces that it could swallow.
tyrannosaurus Rex was the largest carnivorous dinosaur that lived in North America in North Africa had two carnivorous dinosaurs both bigger than tyrannosaurus Rex spinosaurus and charcharodontosaurus
IF there were a large percentage of T Rex's compared to "accepted" carnivores towards the end of the Cretaceous, then could this support your theory about them as scavengers and, if so, and there was an increased number of large scavengers at that time, do you think there was a gradual dying off of dinosaurers in effect before the comet hit?
He can't just ignore the evidence of healed T-Rex bitemarks on various prey items. T-Rex was probably like most predators: It hunted and scavenged. Why expend all that energy if there's a carcass lying about, or easy to steal?
Not to mention in areas where it lived it was the only large dominant predator, and herbivores in the area showed no signs of genetic weakness. Because without regular predation to cull the herd, the species gene pool has nothing to drive evolution and non beneficial mutations pile up. But herbivores in the area are fit, and have injuries from T Rex predation
Dragging a big tail is not a problem at all. Look at the size of the tail Godzilla is dragging around. And there he is, right up on the silver screen, big as life.
Dr jack horner is a brilliant paleantologist tyrannosaurus Rex was probably both a scavenger and a predator there is fossil evidence that tyrannosaurus Rex was not simply a scavenger it did attack triceratops tyrannosaurus bite off the horn of triceratops and then bite into the frill of the triceratops and most importantly the bone rehealed showing that triceratops survived a live attack from tyrannosaurus Rex and survived the attack showing that tyrannosaurus Rex did attack live prey aswell as scavenging eating carrion of already dead dinosaur carcasses
in 100,000 years we will have dinsaurs again for sure. But in already 10 years we will have ultra realistic dinosaurs in virtual reality. They will look like giant crocodiles.
So many professional paleontologists in the comments. Lol its easier to criticize and give baseless opinions than actually going out and digging for them and studying them for years.
I love all the arm chair paleontologists. So many desire to do the work but rarely are able. They enjoy it from these videos and love to voice their opinions, and that's good. However, It's a tough job and requires a deep seated passion. Many of my students gave up quite easily when having to jacket a 1000 pound bone in 100 degree temperature or work hours tediously cleaning the bone from a plaster jacket. It's tough work but rewarding. I met Jack numerous time when he lectured ar the University of Florida. He always was engaging and had great lectures. I remember one time in the 1990s I challenged him about his being so convinced that dinosaurs were birds. He responded to me " They're Birds They're Birds They're Birds!" That's one of my favorite memories of him. I was later only convinced of their bird ancestory when I attended a symposium in 2000 to review the new feathered dinosaur fossils from China. Just when you think one way a new bone comes along and changes all that you believed. Still digging and researching after 50 years. Paleontologist rarely retire completely.
T-Rex has been analyzed in terms of mechanical advantage of skull support, angular momentum when turning, strength of ribs for supporting the body, agility with neural transmission delay, grappling advantage, ripping advantage, walking speed, etc. None of these point to T-Rex as primary predator. The healed tooth marks argue against rather than for a predatory T-Rex. Primary scavenger T-Rex does seem to be the only hypothesis that matches the physical characteristics of T-Rex Sorry.
Questions. If T-rex isn't the primary late Cretaceous predator, who is? Where'd the bite marks come from? Why are all the contemporary herbivores so specialized in their defense mechanisms? How did T-rex grow that big just from scavenging? Where were all of these easy meal carcasses coming from? Why did it develop such powerful bite force? What need does a scavenger have for semi binocular vision? Why are there so many tyrannosaur fossils?
We will eventually know how dinosaurs looked and how they lived in their individual ecosystems. With quantum computing, we'll be able to run advanced simulations that will recreate prehistoric times with 100% accuracy - based on the data scientist input that is.

"...just remember... an opinion isn´t worth anything! " Now that is a saying that should be said quite a lot more.
I'm 12 and love jack horner and his work!
Now you're 20
@@flyinglizards80 Yeah, and I'm not sure how I got here, nearly 21 lol
An interesting and informative talk from one of the Paleontological greats!
thanks for sharing Illinois Mathematics and Science Academy (IMSA)
Dr jack horner is a great scientist a brilliant paleantologist
Dr Jack Horner is a Brilliant Paleontologist! 🦕🦖
Curved surfaces are good for transferring energy. Base Ball Bats, Golf Drivers. And round hard football Helmets were used as weapons until butting with your helmet was outlawed.
I guess it never occurred to the camera person that a critical part of the talk are the images on the screen.
Bro this takes me back I remember I went to one of his speeches in Richmond
Talk begins at 03:35
❤ Jack Horner he’s a Brilliant Palaeontologist 🦕 🦖
"Politics or Law", where the truth is treated as subversive and against the ruling narrative. Paleontology is the the most re-creative of human sciences other than Mathematics, that is all there is.
Could have been possible that T-rex was both hunter and scavenger, no?
Ofc why not
There are fossils that show strong evidence of both scavenging and active predation.
Jack, now we’ve got juvenile Tyrannosaurus rex. 3
Love Jack. Has anyone else noticed he also sounds like Will Ferrels Anchorman Ron Burgendy ? 😬
I met him in 2016 I'm not joking I actually met him and even got a picture with him
Lucky
i thought they found trex teeth marks that healed up did hunt live prey and scavanged,, even vultures hunt live prey ,
Terrible camera man
Interesting talk though

He's got such antipathy for the T-Rex.
Love Jack Horner but the camera work is very very poor
Dragging a big tail is not a problem at all. Look at the size of the tail Godzilla is dragging around. And there he is, right up on the silver screen, big as life.
But Godzilla isn’t real, it’s a made up creature for a movie, anything is possible in movies 😂

Please use interpunction man.
Why woulndt trex scavenge and hunt?what did i miss?
in 100,000 years we will have dinsaurs again for sure.

plavix221 before 2050 we will have them back again

This is an amazing man and scientist. Dr. Horner is dyslexic and can barely read. By the standards of today, he should be on the dole.

I'll bet if there were a T rex about 200 ft. From you..your opinion might quickly change. I disagree with Jack. T rex would kill for sport too.
@@PaulBunyun1954 Don't bet your house on that. I was within 10 feet of the Lucy display. It clearly was not a predator.

So false data will lead to false conclusions
humans are dinosaurs too cause we have tailbones
