9 ton ambush predator that could smell in 3d see you from 2 miles away and high speed walk you to death. Now it never roars. The woods must have been terrifying back then
Just think of the bugs back then. Like a 8 ft long cockroach or a spider with legs as long as yours. I’d want to rid a T-Rex tho. That would be my downfall.
Now they think it may have had nerve endings in its teeth that detected vibrations off of prey. They found holes in its teeth. It smells you and feels your movements. cross its path and it simply walks you down.
Those cow bones are shattering way before 8000 pounds of pressure. a crocodile can crush a cows head, you should of used an re-creation of an elephants skull to better simulate the damage done by Trex bites force.
@@rodrigopinto6676 I was just referencing what the guy said, either way they could of used something better to test the might of the trex bite force. I remember seeing a documentary years ago, Where they made a pair of steel hydraulic Trex jaws and used them to crush the engine block and chassis of a car. That was pretty impressive to watch.
It took a bite and waited for its venomous saliva to deliver the coup d’grace. No dangerous combat needed to bring down prey. The teeth produced wounds to allow the venom to get inside the prey animal and gradually kill it. Goes without saying T Rex was immune to its own poison.
Cool documentary, whenever it's voice is a low pitched rumbled or a terrifying roar, it doesn't matter to me, as I'll always love Tyrannosaurus rex and I always will: TEAM TYRANNOSAURUS REX FOREVER!
Terrible /terrifying are two different words that don't mean the same thing. They used the word terrifying. You're right though ,humans are the most terrible.
They didn't mention it but computer models proved Tristan was a huge KISS fan Also, I didn't think it was possible to make a T-Rex seem unintimidating, but naming it Tristan is damn close
Glade .. u should b terrified u now live along side of the greatest predators the 🌎 has ever seen.. Humans.. they make T Rex look like a 🐕.. N there armed... 2 the Teeth......👋😊
It's pretty widely accepted at this time that T. Rex had little to no feathers. I'm glad this documentary covered that. Including potential sounds was just the icing on the cake. Wonderful documentary, thanks for sharing your studies with us.
The Punk hair looks ridiculous and there is no evidence that they existed. Head and Neck skin impressions so far collected show no signs of hairs or proto feathers.
With that sense of smell, it just has to follow the prey to its den. Like komodo dragons, they follow their bitten and poisoned prey till the prey drop dead.
They will say anything to get their name in the books next to a discovery, couple that with the possibility of funding when seeking information about a "new species" and you don't have to look very far into paleontology before stretching the truth is common place for quite a few people im just saying. This isn't anything new but it is the truth 😎🤷
how the low soundings of the beast may have effected us if we were hearing it would be somewhat like the Jaws theme from the film, it would build suspense and make one jumpy, causing fear to rise
17:21 Glad she addresses that . Think they may have, at best, hissed, possibly that infra/subsonic vibratory effect, but that roaring business? Ever hear an alligator roar, a gila monster, any lizard?
If T-Rex was as smart or smarter than a bird such as a Parrot or a Raven. It's crazy thinking about if they could be trained like one. And imagining having a T-Rex as a pet. Lol
Fossilized T-rex skin shows it did NOT have feathers. Not sure what the fascination is with randomly putting feathers on dinosaurs, even when proof they did not have them exists.
This is an old documentary from before the T.rex skin had been discovered. At that point, T.rex was being depicted with feathers since the large tyrannosauroid Yutyrannus was discovered with feathers on all three specimens (and a feathered specimen of the much smaller Dilong had also been discovered), so it was assumed that every member of Tyrannosauroidea would have them.
The thing is, by now feathers and feather like structures are considered to be ancestral to dinosaurs as a whole, as well as their closest relitives the Pterosaurs. And just like how a few Whales still retain some form of hair on their heads, T-Rex most likely had very fine feathering as well. For a better look on how Tyrannosaurus looked like, the Prehistoric Planet reconstruction is most likely the closest we have to the actual animal.
There's not a single example of evidence of Trex having any feathering whatsoever. The current push to suggest that TRex had feathers comes almost entirely from the paleo art community. There's a whole industry that consists of people drawing and recreating dinosaurs. There's a lot more money to be made if they can convince everyone that TRex was feathered. Hence all the recent examples of Trex having ridiculous feathering such as mohawks and the like.
@@peteblackburn7850 Recent paleoart does not show so big feathering on T. rex in any serious compacity. The biggest feathering is as much as a little leftover fuzz from being a chic. As I said before it is pretty universally asccepted that Dinosaurs were an ancesteraly fuzzy clade.
“Often thought of as tail dragging bloodthirsty reptiles” transported to modern times its art would surely have rivaled Van Gogh or Mattise it was so much more complicated that we think ! 🤔
0:31, 5:04, 9:42-9:47 & 17:25-17:32 I know where those clips came from, they’re from the 1978 Film Planet of Dinosaurs. Bonus: 20:46-21:02 At 1st glance these Elephants look like the ones from the Savanna, but these are Forest Elephants from the Congo.
@@sforza209 No, That T.Rex from Planet of Dinosaurs was animated by Jim Aupperle & Doug Beswick. But Ray did however animated a T.Rex from the 1956 Film The Animal World alongside his mentor Willis O’Brian. Come to think of it, T.Rex from Planet of Dinosaurs looks a little like the T.Rex from The Animal World. Only a little bit Bigger & beefy AKA Muscular than its 1956 predecessor.
What's scary about the gator's bite force is that in this test, the gator is roped or tied down with a man on top of it, so it's actual bite force without it's body and jaws being confined is probably waaaay higher. It's a seriously deadly animal.
Theropod dinosaurs weren’t reptiles but amped up flightless birds with complex social behaviour, The updated depiction of T Rex looks like an endothermic animal, a capable apex predator.
Interesting that the fossils couldn’t shed light on how a T-Rex would look like. Until the T-Rex named Sue. T-Rex was bare skinned. The feathered Dinos were small. T-Rex would have overheated with feathers. And Earth was likely very warm like tropical weather because plants and insects were gigantic. T-Rex Sue actually looked cute not menacing. T-Rex was deceptive and T-Rex can sprint fast. T-Rex loves to hunt and chase the prey. So no way was T-Rex slow.
Some contend that T-Rex was a scavenger, while others contend it was a hunter. I think it was both. We know from a lot of carnivores today that they are both hunter & scavenger. They will hunt, usually by ambush, but won't mind an easy meal if its already dead & they happened upon it. We know that T-Rex had excellent eye-sight & excellent smell, but its forearms are mostly useless. Sounds like an ambush predator that would scavenge if needed to me. And as an ambush predator, he would need to blend into the environment. I envision it was a greenish-brown, with maybe some variation on the head.
Some have speculated that larger Tyrannosaurs existed. It's very possible since gigantism, though rare, did (and does) exist in some modern animal species. Whilst nothing the size of Godzilla has ever existed; I believe there were larger Rexes than the ones whose fossilised bones are exhibited in the world's museums. There is only a small percentage of fossil material which we have. What else there is to be discovered, regarding T-Rex, is anyone's guess.
One of the few things I take issue with is how the surface features are applied. I agree with the body coloration, but it's the "mane" I have trouble with. Do we, in fact, know that the feathers were spiny structures? Or were they hairlike, like the hairy feathers of an emu? I propose that since Trex didn't use a roar to intimidate it's aggressors, that it had another way to do it. The head and neck feathers could well have had areas of differing length, and he might have had control over how much of them he could move. By way of example, many birds have eyebrow tufts or throat ruffs they can enlarge or fan out for display. One such bird is a Raven, who uses its eyebrows and neck ruff to communicate with others while negotiating over animal remains. Then there's the Great Horned Owl, whose ear tufts are very expressive. Birds have an astonishing array of feathers used for social interaction. A crest off the back of the head, two crests that resemble clusters of pens over one's ears, a waterbird with a nose crest. Fans of head feathers behind the head. Could a T-Rex have a wattle or skin areas around the eyes that were either yellow or red, allowing him to make vocalizations outside of his skull using a bladder-like wattle that would inflate. I think about the ruffed Grouse, who announces his presence by beating his wings upon his breast as he inflates it, creating a sound that resembles a motorcycle starting up, slow, then fast. There are lots of birds, reptiles and mammals that use gurgling or whistling sounds made in the nasal passages. I could go on at length about the possibilities, but I want to emphasize the point that the ruffed T-Rex is not as intimidating as he could be, given the parameters. Simple fuzz is not really enough, in my honest opinion. The other thing that didn't have any data presented for, was the stride length. Yes, you have footprinst preserved in mud, but were thos prints of a striding dinosaur, or were they running? Given the ratio of numbers between hip and heel, that much should have been available. I have a hard time believing that a creature that was built for running after prey as a teenager, is reduced so dramatically in speed as an adult. Are there any corollaries to that scenario? I am an artist, and I am very often called upon to draw things that don't exist in a realistic way. That means I have a working knowledge of physiology, body morphology and a mental library of hundreds of species and how they compare. I have to say that the walking/running sequence of the T-Rex just seems wrong to me. It's missing the gracile motions of a hunter or ambush predator. When it runs at a moderate pace, the whole creature should look like a well oiled machine, with all parts working smoothly. Your cgi model lacked that. It actually looked like someone had hobbled it"s ankles, restricting stride length and making the whole creature looke awkward and unreal. In every other way I liked your presentation and I'm glad I watched it.
I think you should revisit your conclusions on speed. Your digital model indicated a flaw in your thinking... I imagine the hips, body and tail making much larger side to side motions as the animal lift and accelerated off each leg, which would make better use of the tail muscles. It would look more like a swimming motion for a crocodile while running, which brings me to my second point he was probably just as fast in the water as he was on land
Amazing, how the front limbs were almost vestigial, something must have happened to make them flip and elongated to hollowed bony wings. From lizard to chicken/bird, giving us fried chicken/KFC, etc. getting eaten by us instead of us being eaten by them.
Because of Size I will again Reference the Elephant. The Elephant, an Animal that does not Chase its Food, nor is it Chased as Food is Clocked at 25mph. I think its Safe to Assume a T-Rex was Significantly faster than an Elephant.
Go ahead and paint me crazy but I'd be much more frightened of a roaring T-Rex than a softly murmuring one like the crocodile sound the two scientists were shuddering to.
Trust me bro. You have NO IDEA how terrifying a real T-Rex is. They don't roar at ALL and when one sees you it will grunt looking upwards at you. This animal is very terrifying. Believe it or not they live in the unknown jungles of Australia. Horses run in fear of its odd silent sounds. Your horse would leave you behind, your dog would bark warning you to stay away.
It would have likely have been able to "roar" in a sense by creating booming calls with its throat. And what would be the horrifying part of its noises isn't just that you'd hear it, you'd FEEL it throughout your entire body, the air and the ground.
Trust me bro, you can have no confirmed idea and simply speculate since your direct exposure to these animals in their natural environment is likely on par with my own (which is zero). For all we know, T-Rex purred like a kitten and barked like a dog. And given the highly speculative and evolving nature of theories in this field, you might want to consider turning down the authoritative tone of your comments. @@fruitybluieblue098
We wonder why the Dinosaurs died out but the birds and crocs lasted to the present. One of the things that we don’t consider is that crocs and Gators do not suffer infection despite living in some of the filthiest environments on the planet, now we also know that the Dinosaurs did suffer from terrible infections. I suspect that the asteroid that hit the earth was only the start of the end for the dinosaurs and infection and starvation was the major reason for extinction. Birds on the other hand were smaller and eat seeds and insects so food may not have been too much of a problem for birds.
I’ve been to the same “Dinosaur Valley” Park in this video multiple times and spent, often days at a time studying the same track shown here to the right of the Theropod tracks. 25:58 The claim that there is no evidence for “tail-dragging” is blatantly incorrect and misleading. There are many long, deep grooves that accompany many of the different types of tracks. I can’t believe this video leaves out so many details about the tracks found here. Also, most of the tracks are of the Sauropod variety and there are very few Theropod tracks, that appear significantly smaller than you might expect. The ones there are, however are said to come from an entirely different dinosaur and not an actual T-Rex. This is the same river that has human tracks and footprints embedded in the same layer of rock that has the dinosaur tracks. However, This is an amazing place to visit and would definitely recommend anyone who loves dinosaurs or has children that do, visit at least once in their lives. I actually found the fossil of a small 2”x4” fish in a pile of slate along the river side. I have a few photos but didn’t keep it as it is illegal to take ANYTHING out of a State Park in Texas. The Museum of Natural Science in Houston has a photo of the actual fossil on their Facebook page.
dont like your meter test either make the pad as lade as the bite im going to guess that theres a differance on the force meter from a tooth or ten just from the surface area
Could T-Rex in its life have hopped like a kangaroo for more speed than just running or perhaps like a raptor for an attack advantage, such as a young one being able to get prey herded toward waiting parents for the kill? They seem to have bodies that have kangaroo physiology at different points in there lives…just a thought, I am no paleontologist by any means, just an old guy with a question. I throughly enjoyed the video, keep up the great work.
Yes and no. It can be compared to other animals but something like an Ostrich femur would be better, since the bones are hollow and T-Rex (just like pretty much any other land predator) more so went for the throat and limbs of it's prey.
I thought that there was another dinosaur that was similar to T Rex but that it was actually larger than T Rex. I have heard that several times before, but maybe it didn't exist in the same time period maybe it evolved from the T Rex.
The giga is thought to be as tall and long as a T-Rex, but after studying its bone structure it was designed for slicing and biting chunks- where the Rex was designed for crushing force and pulverizing bone. The Rex had a much thicker build and was heavier. Especially, with newer leg bones recently discovered the T-Rex keeps getting bigger.
That's what I tell my birdies every day, "you're the smartest animals in this world, and your ancestors once ruled the old world" 🖤
counterpoint, I watched my little dog(no wings)ambush a bird eating seeds on the ground. That was pretty dumb, no?

I find the low-pitched rumble portrayed here way more intimidating than the traditional roaring of Hollywood dinosaurs,
Since birds can vocalize loudly both with their beaks open and their beaks closed. No reason dinosaurs couldn’t do the same.
And who says dinosaurs roared anyway... the movies? We'll have to ask a Southerner if Gators roar like that.
“Birds” is a very broad term. Some are louder than others and the males calls are different than females, remember that.

Could a T-Rex have a wattle or skin areas around the eyes that were either yellow or red, allowing him to make vocalizations outside of his skull using a bladder-like wattle that would inflate. I think about the ruffed Grouse, who announces his presence by beating his wings upon his breast as he inflates it, creating a sound that resembles a motorcycle starting up, slow, then fast. There are lots of birds, reptiles and mammals that use gurgling or whistling sounds made in the nasal passages. I could go on at length about the possibilities, but I want to emphasize the point that the ruffed T-Rex is not as intimidating as he could be, given the parameters. Simple fuzz is not really enough, in my honest opinion.
The other thing that didn't have any data presented for, was the stride length. Yes, you have footprinst preserved in mud, but were thos prints of a striding dinosaur, or were they running? Given the ratio of numbers between hip and heel, that much should have been available. I have a hard time believing that a creature that was built for running after prey as a teenager, is reduced so dramatically in speed as an adult. Are there any corollaries to that scenario? I am an artist, and I am very often called upon to draw things that don't exist in a realistic way. That means I have a working knowledge of physiology, body morphology and a mental library of hundreds of species and how they compare. I have to say that the walking/running sequence of the T-Rex just seems wrong to me. It's missing the gracile motions of a hunter or ambush predator. When it runs at a moderate pace, the whole creature should look like a well oiled machine, with all parts working smoothly. Your cgi model lacked that. It actually looked like someone had hobbled it"s ankles, restricting stride length and making the whole creature looke awkward and unreal.
In every other way I liked your presentation and I'm glad I watched it.
The skin that they found of T-rex in Montana showed no signs of feathers or pen feathers.
I think you should revisit your conclusions on speed.
Your digital model indicated a flaw in your thinking...
I imagine the hips, body and tail making much larger side to side motions as the animal lift and accelerated off each leg, which would make better use of the tail muscles. It would look more like a swimming motion for a crocodile while running, which brings me to my second point he was probably just as fast in the water as he was on land
Love how they make up all these thing with no real data it’s mostly guessing.
if t-rex is gonna sound like a bird i'm not watching anymore jurassic park
a song bird ! , lmao!
nice press but we already have bones we know was biten by t rex and they werent dusted second if it was doing so there wouldnt be many sculls to find
I believe the rex would have ran more upright
Amazing, how the front limbs were almost vestigial, something must have happened to make them flip and elongated to hollowed bony wings. From lizard to chicken/bird, giving us fried chicken/KFC, etc. getting eaten by us instead of us being eaten by them.
They Already Have
I too fall and hurt myself
A pride of Tyrannosaurus's 🤔
Because of Size I will again Reference the Elephant. The Elephant, an Animal that does not Chase its Food, nor is it Chased as Food is Clocked at 25mph. I think its Safe to Assume a T-Rex was Significantly faster than an Elephant.
Jeez, how many adverts?!?!
Dinosaurs were not lizards. Dinosaurs had hollow bones like birds. And they even had feathers.
So you know better than scientists and paleontologists.. got it
Go ahead and paint me crazy but I'd be much more frightened of a roaring T-Rex than a softly murmuring one like the crocodile sound the two scientists were shuddering to.
Trust me bro. You have NO IDEA how terrifying a real T-Rex is. They don't roar at ALL and when one sees you it will grunt looking upwards at you. This animal is very terrifying. Believe it or not they live in the unknown jungles of Australia. Horses run in fear of its odd silent sounds. Your horse would leave you behind, your dog would bark warning you to stay away.
I like to think they sounded like crocodilians, loud rumbles and hissing, a loud roar would just scare any prey away
It would have likely have been able to "roar" in a sense by creating booming calls with its throat. And what would be the horrifying part of its noises isn't just that you'd hear it, you'd FEEL it throughout your entire body, the air and the ground.
I think they could do an open mouthed roar and closed mouth rumbling bellows
Trust me bro, you can have no confirmed idea and simply speculate since your direct exposure to these animals in their natural environment is likely on par with my own (which is zero). For all we know, T-Rex purred like a kitten and barked like a dog. And given the highly speculative and evolving nature of theories in this field, you might want to consider turning down the authoritative tone of your comments. @@fruitybluieblue098
Given that we found a Pinacosaurus vocal thing this rumbling theory is too limited
Why are so many commentators used making relative stupid comments when one would suffice.
We wonder why the Dinosaurs died out but the birds and crocs lasted to the present. One of the things that we don’t consider is that crocs and Gators do not suffer infection despite living in some of the filthiest environments on the planet, now we also know that the Dinosaurs did suffer from terrible infections. I suspect that the asteroid that hit the earth was only the start of the end for the dinosaurs and infection and starvation was the major reason for extinction.
Birds on the other hand were smaller and eat seeds and insects so food may not have been too much of a problem for birds.
I’ve been to the same “Dinosaur Valley” Park in this video multiple times and spent, often days at a time studying the same track shown here to the right of the Theropod tracks. 25:58
The claim that there is no evidence for “tail-dragging” is blatantly incorrect and misleading. There are many long, deep grooves that accompany many of the different types of tracks. I can’t believe this video leaves out so many details about the tracks found here. Also, most of the tracks are of the Sauropod variety and there are very few Theropod tracks, that appear significantly smaller than you might expect. The ones there are, however are said to come from an entirely different dinosaur and not an actual T-Rex. This is the same river that has human tracks and footprints embedded in the same layer of rock that has the dinosaur tracks. However, This is an amazing place to visit and would definitely recommend anyone who loves dinosaurs or has children that do, visit at least once in their lives. I actually found the fossil of a small 2”x4” fish in a pile of slate along the river side. I have a few photos but didn’t keep it as it is illegal to take ANYTHING out of a State Park in Texas. The Museum of Natural Science in Houston has a photo of the actual fossil on their Facebook page.
dont like your meter test either make the pad as lade as the bite im going to guess that theres a differance on the force meter from a tooth or ten just from the surface area
Could T-Rex in its life have hopped like a kangaroo for more speed than just running or perhaps like a raptor for an attack advantage, such as a young one being able to get prey herded toward waiting parents for the kill? They seem to have bodies that have kangaroo physiology at different points in there lives…just a thought, I am no paleontologist by any means, just an old guy with a question. I throughly enjoyed the video, keep up the great work.
She thinks T-Rex whistled like a robin
Is the cow skull comparable to t Rex’s real prey? Would a dinosaurs bone be stronger?
most dinosaurs had hollow bones so the cow skull would likely be more dense
Yes and no. It can be compared to other animals but something like an Ostrich femur would be better, since the bones are hollow and T-Rex (just like pretty much any other land predator) more so went for the throat and limbs of it's prey.
T Rex didn't roar, low growl and chirbs like an owl would do , likely feet were padded to reduce noises.
That’s much more scary
Pay aTTENTION FOLKS, THE SOUND OF TREX IS LIKE PSEUDO SCIENCE LOOKS LIKE
15 tonnes scariest Apex predator don't have enemy but ankylosaurus how ?
It seems the T-Rex would have venomous saliva, similar to the Komodo dragon. I believe it would bite and sniff out it prey and then slowly exhaust it.
The classic Trex looks shorter
I thought that there was another dinosaur that was similar to T Rex but that it was actually larger than T Rex. I have heard that several times before, but maybe it didn't exist in the same time period maybe it evolved from the T Rex.
The giga is thought to be as tall and long as a T-Rex, but after studying its bone structure it was designed for slicing and biting chunks- where the Rex was designed for crushing force and pulverizing bone. The Rex had a much thicker build and was heavier. Especially, with newer leg bones recently discovered the T-Rex keeps getting bigger.
X the Mane in my opinion 😅
what color was the T-Rex?
pffff....that's easy. everybody knows that they were purple!
T Rex doesn't need to be audible, since it's prey had some formable defenses.
