Was the T-Rex and other Theropods more suited to walk than run? Dr. Moo breaks down how we have been lied to about just how fast and how able a T-rex could run or even walk while chasing its next meal.
most of its "prey" could not run either same issue too big too heavy ...also they scavenged just think how much free meat was arond due to normal injpoory and age of the really really big ones falling over
it has long been my hypothesis that the T-Rex, with its numerous adaptations for long distance tracking (acute sense of smell, excellent eyesight and binocular vision), would chase its prey to exhaustion similar to how canines would hunt, using their sense of smell to continue to pursue prey which has long left its line of sight until it catches up eventually. this style of hunting would also take advantage of it's long legs and bulky head, a T-Rex could step over or barrel through obstacles that its prey would have to run around, climb over or swim through, its excellent binocular vision would allow it to spot and avoid serious obstacles like trees since it wouldn't have needed its eyes to track its prey, and it could use its massive head to shove aside, or knock over, smaller obstacles also its long legs would allow it to walk through most rivers or ponds without needing to swim.
I do agree with that, however You should also note that tyrannosaurus wasn't built in a single shape that didn't change through time. My idea is that the younger more juvenile forms of tyrannosaurus were suited to hunt fast running, agile prey because they were lightweight. Whereas the larger, heavier, and more mature tyrannosaurs prefered to hunt armoured prey, or even large ornithopods ( For Example ).
@@lilgary9181 A seven ton carnivore could not survive off of scavenging. That idea came from comparing T-Rex's ridiculous jaw strength to the spotted hyena, which also has a very high jaw strength and can crush bone. Crushing bone was important to T-Rex because its prey was armored. More recent studies have shown that hyenas do not scavenge more than any other predator. They use their overpowered jaws to eat more of a kill than other predators can. Their overpowered bites also give them a fighting chance against much larger lions which they directly compete with for prey.
The real T-Rex, yes. The Jurassic Park version, no. In the first movie they explicitly say that they clocked the T-Rex at forty miles per hour. Remember the Jurassic Park dinosaurs are genetically designed theme park attractions, not real dinosaurs. Made from deteriorated DNA mixed with frog DNA, at most they're mutated hybrids, not the resurrections of extinct species.
@@mikemalley1909possibly. Most people can run around ten miles per hour, healthy people can run around fifteen miles per hour, and athletes can run twenty to twenty-five miles per hour with the record being twenty-seven point eight miles per hour. It really depends upon what shape she's in and what shoes she's wearing. In high heels, it would be difficult and unlikely.
I was entertained and feel more informed by this video, just saying. Not to sound like a simp, though. I’m just not afraid of change. LOL. But seriously, I’m happy to see this channel still going, and happy with the good doctor helping keep that curiosity fed.
kind of makes sense if you've got any sense of material strength. The same problems we have with building walking machines are present in dinosaurs, in that there's not many materials that can withstand the force of running without also adding too much weight to allow for running
Just in case anyone is wondering these are the two studies that the narrator is talking about in the video : - peerj.com/articles/3420/ - journals.plos.org/plosone/article?id=10.1371/journal.pone.0223698#sec009 Its important to mention that in a technical sense running is usually defined as an animal having an "airborne" phase which includes having all of their feet off the ground at one point or another in their stride. You'll see such a phase in the sprinting cycle of most modern animals under 3 tons or so (Cats, Bears, Artiodactyls, Ostriches, Rhinos, humans, horses etc). By contrast when you see large animals such as Elephants and Hippos sprinting at full speed you'll notice that their gait is mostly reminiscent of a _really_ fast "walk" since they never have all of their feet off the ground. In the 2017 study from Bell et al I linked they elaborate on this a bit more : _"There are two definitions of walking and running that are commonly used when considering bipedal gait. The traditional definition is “progress by lifting and setting down each foot in turn, so as to have one foot always on the ground” (Shorter Oxford English Dictionary, 2007). This definition translates to duty factors: walking has a duty factor of >0.5 and therefore has a period of dual support, whereas running has a duty factor of
You left out the most important part: the large theropods were as much of pack hunters as their smaller counter parts. That means they didn't *need* to run as fast when they could just surround their prey.
Adults tyrannosaurus where too heavy to run but younger juveniles and teenage tyrannosaurus due to their lighter bone structure could run. Also I though tyrannosaurus was 9 tons
Is Carnotaurus (the "Cheetah of theropods") included in the list of theropods that can't run? It's a larger theropod that has been famous for speculated high speed sprints from what I understand.
It's not about could theropods run or not, these creatures have multiple stages in their lives in which they were suited to a particular niche in their environment. This would change as they grow and mature, as they become for example less capable of sprinting and more suited to hunt bulky or armored prey.
OK so that is all well and good but the other half of the equation is- How fast were their prey animals moving? Because if a theropod could only get up to 17 mph, but if sauropod could only get up to say 8-10 mph, then relatively speaking, they're still pretty fast! Looking forward to the Part-2 to clarify this, thanks!
Question, hypothetically, if the earth spun faster in the past how fast would it need to spin for the centrifugal force to offset gravity enough so the T-rex may have been leaner/lighter so that it could run over 30mph.... asking for a friend.
This would not be as big of a problem as most people would think. Their offspring might have stayed in a group, like a hunting group of wolves. The juveniles and subadults might have been able to run and spook the prey until it tired so that the big parents can deal massive damage. Some members used power, others speed. The ability for T-Rex to grow so large from a tiny hatching likely also explains why there is a lack of medium sized dinosaurs in their ecosystems-the babies might have changed niches as they aged.
The film Jurassic Park is 27-years-old this year and it seems unfair to reference it and state it lied to us. Back in the early 90’s we didn’t know as much about Rexy as we do today which is why Jack Horner and their team hypothesized the Rex’s eyes would be based on movement and be able to use its long legs to run fast. After the film was such a huge hit, scientists started studying this uniquely limbed animal and started to figure out that it couldn’t do the things it did in the film. Even if this video were to reference the sequel, Jurassic Park: The Lost World (1997) you would see people running away from a rex on foot because science had since proven rexes couldn’t run fast and the filmmakers wanted to be as scientifically accurate as possible. I think it’s unfair to first off state that a film lied to us when no one knew any better at the time. It’s also ridiculous to use a reference that’s older than 10-years-old as a constant source. I used to teach English and always told my kids that any source older than 10 years isn’t worth looking into because it was probably outdated information. Sorry to sound negative but I have a passion for film and dinosaurs. The power walking information was very interesting and that was a positive take away from the video.
I have a pretty good idea that you guys could make. I would love to see it. Could you train your muscles to a level in which your muscles can stop a close range shotgun like mr. Unchained in Baki series??? I would love to see a scientific video about that 😍😍
Not a bad video but i juat cant get into the cannel anymore like i use to. Kyle really brought people. I see the views dropping likes too. I dont dislike the video but you guys need to step it up to bring me an others like me back. Idk what really but something is missing and theres no replacement for Kyle but im sure with a change of style and some hard work this channel still has potential. DONT LET THE CHANNEL DIE PLEASE JUST MAKE SOME CHANGES.
Tyrannosaurorids had a unique feature called arctometatarsal where the middle metatarsal is pinched between the others to evenly transmit force, this is not found in other large therapods but is common in certain sorts of dinosaurs accustomed to running such as ornithomimosaurs, and troodontids. Palaeontologist David Hone went into some details about this in one of his lectures ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-08KKeW8I_nM.html
I find it hard to believe some people born in the last few decades can tell me something which lived "millions" of years ago ran or walked. Nothing more than fancy guesses. My Dinos are track stars.
La resistencia en animales es el máximo de eficiencia en su metabolismo a pesar de ser este lento o rápido la convergencia evolutiva es muy difícil de estudiar sobretodo animales extintos pero no es muy común como el bipedismo animal.
Makes sense it likely ambushed prey bite them and follow like a komodo dragon bite then follow slowly wait for infection or exhaustion and go in for a killing blow
Keep in mind that the dinosaurs in Jurassic Park are not really dinosaurs: they're genetically engineered approximations of dinosaurs. "Life, uh, finds a way."
You can safely say that jurassic park dinos are one of the older interpretation of the real thing. Or maybe hollywood monsters based on living creatures dead or alive on par with godzilla and the likes.
I was a bit (...) of a jerk about her being a supplement or replacement for kyyyyyle I think that Keeeyyle's thing about being able to write ambidextrously and other aspects about his character is important to these presentations. Mu, I'm sorry for bashing you based on video production. But this channel is really his. Even Houdini had to deal with the passing of torches.
Can we dial back on the bone structure not being viable for running for just a minute ? We need to take tissue structure into consideration before we say that an animal can't run. Elephant bone structure by itself would indicate that they can't run either but the bottom of their foot is coated with a fatty "shock absorber" that lowers the impact and allows them to run. We see elephants run, It's feasible for T-Rex's to have developed a similar tissue structure in their feet. In the case of this video, we're effectively looking at the rim of a wheel and saying it can't ride over bumps because it would warp the rim. But then never exploring the idea of a tire fitting around it.
The information at that time was certainly enough to backup real scientific accuracies So a frilled dilophosaurus or a 6 feet high froggy eyed raptors shouldn't be excused for movie monsters
@@doublesalopetoimcre im only sticking around to see what they do with it before deciding, but im mostly out as well. Kyles new channel and show is so good.
@@brandnamevideos8419 that wasn't the full answer for the question. he asked, what happened to Kyle? He was the star of the channel. Why did he decided or forced to leave?
@@doublesalopetoimcre well one thing is he was limited to what was made and he wasnt able to be as interactive as he would like to. Also they had creative differences like how the show was going. Also that would anwser the question which was where did kyle go. Well he left the channel is implied when you say he has a new channel.
35 years ago, 10 year old me, figured out that T-Rexes were more like vultures than cheetahs. Definitely more like scavengers than prey hunters. Their arms are way too small and short to be able to capture and hold onto prey large enough to supply they're necessary caloric intake to remain so large.
T rex is more like wolf and us than cheetah. T Rex are definitely hunt more than scavenge as stamina hunting like wolf are actually more effective hunting as Cheetah, the fastest runner are at one of the lowest tier hunter in Africa. T rex also has best binocular vision makes it best hunter. Also having short arm does not mean they not hunter as many hunter rely on jaws only like croc and wolf. Long arm and claws are overrated you claw bias
