What if it was a small, juvenile sauropod dropped from a marauding Quetzalcoatl at, approximately, 5,000 feet? That's going to reach 120 mph before you can say: Duck!
I didn't know crocodilians displayed it too, very nice. So, the whole international phonetic alphabet is very alien to me, and the best way I can explain the pronunciation is "Duh-knee-loh" the "de" sounds like "dea", and lastly "Soul-zah". I appreciate the attempt, though
I’m sorry I butchered it 😂 glad to know for next time though lol I’m curious to know what nationality you are? I’m really trying to work on pronunciations
@dino-gen to be fair, you had no point of reference, considering it differs from how it would be pronounced using English as a base. I'm brazilian, mate
Thanks for the video! This is great! Can you do a video on the smallest dinosaurs? We hear about the big guys, but what about how small they (non-avian dinosaurs) got?
Flying avian? Peregrine falcons Flightless avian? Likely ostriches Non-avian? Ornithomimids, although I grew up reading that it was specifically Struthiomimus that was the fastest of those.
Tyrannoaaurus Rexes and Utah Raptors for speed. Pterodactyls and Pteranodons for flight speed. Icthyosaurs and Mosasaurs for water speed. These had to be the fastest dinosaurs on either land, air or sea, respectively.
T-Rex couldn't run. Pterosaurs, Ichtyosaurs, Mosasaurs...REPTILES! NOT DINOSAURS! Also, reptiles, slower metabolisms than dinosaurs or birds....not fast for anything other than a second or two! Burst speed only! Fish of the time...a shit ton faster than Ichthy's or Mo's and for a longer duration. Birds of the day...faster than Pterosaurs. Dinosaurs, faster metabolic rate than reptiles, lactic acid doesn't build in their muscles, able to maintain high aerobic levels much, much longer...so what you listed...not faster than dino's.
I feel like your average Oviraptoridae and Alvarezsauridae would have probably out-sped your average Dromaeosaurid. Dryosaurids were also insanely long legged..
I humbly disagree that play behavior has not fossilized. Numerous well preserved Bouncy Castles have been discovered in the vicinity of Maiasaurus nest sites. Good Mother Lizard indeed!
With how fast carnotorous was I'm very surprised that there aren't many videos on RU-vid pondering whether it could survive or even thrive in modern day ecosystems. It seems both big enough and fast enough to catch and kill most medium to large mammals. It would be really cool if you could discuss this in one of your future videos. Much love keep up the great content bro.
Pro-tip: use the metric system (or at least include metric values too), so we the 96% of the world population don't have to pause the video every 5 seconds to convert miles etc. to real measurements
I'm not willing to write off adult T Rexes when it comes to running. If the juveniles were so fast, it would seem strange the adults couldn't run. I don't know of a single other animal species in which young animals are fast but adults aren't.
The problem with T-Rex you have consider is the loss or performance due to scale. The reason T-Rex was "slow" was because at that size #1. muscle begins to loose the "power to weight" ratio of muscle mass vs. muscle weight. #2. An animal of that mass takes to long get moving, to long to slow down. #3. It is way to risky for an animal that size to change direction with any speed due to injury, all the connective tissues in the feet, in the legs can't hold back that much mass straining on it with that much momentum. #4. moving that amount of mass at high aerobic levels for any amount of time burns a metric ton of calories and energy. #5. that high of a center of gravity at that weight is not easily directional. An adult T-Rex was probably as fast as a juvenile in total mph, but I think what he meant was speed in relation to size. To things a juveniles size, they were fast, to things an adults size, adults were rather slow. They have also been able to work out, given muscle mass, connective tissue strength, metabolism level, sheer mass and stride length....T-Rex could not "run", meaning both feet off the ground at any time. He could still move at a decent clip, but not fast comparatively.
It certainly is! That video was taken a couple of years ago when I decided to visit the site after I had completed my project on it, so I would have been around 25 :)
And one of those reptiles ARE FLYING ! And the other Reptiles were swimming, so based on lactic acid limitations in muscle tissue of reptiles,, and low metabolic rate those swimming reptiles weren't doing anything for length of time....a burst here and there,, but not more than a few meters at a time....period.. IN THEIR RESPECTIVE ENVIRONMENTS...um, no, not at all....fish were faster and so were birds that flew alongside pterosaurs. Especially not the larger Pterosaurs because at their size and weight the fragility of their bones would not allow them to put large or sudden forces on their bodies. Long slow gentle movement, yes. Sudden forceful, swooping, diving, pulling up hard, pumping heavy strokes generating speed..nope, no speedy boys there. Even on smaller scale birds, the largest, highest span species are all "respectively" slow. Birds, higher metabolism than reptiles....faster.
Impossible to know, since most animals are non-domesticable. Crucially though, we have no idea how high or low maintenance each one would be, what percentage of fat and muscle fiber they had, what the exact growth rate was for each genus, and so on. If I had to take a guess anyway, I would say a kind of titanosaur would be ideal, but you'd have to slaughter them before they became unmanageably big.
Due to a 2019 study on Dinosaur locomotion by Larramendi; it has estimated that Velociraptor, due to its smaller size would actually run at around 20 mph. As for the Nanotyrannus information, it’s still under heated debate, not official….yet.
I feel like a lot of these top speed estimates are kind of laughably conservative, considering that we have currently living therapods, much smaller than velociraptors that have top ground speeds that match this in spite of not having counter balance tails for example, roadrunners, which have been regularly recorded as traveling at speeds in excess of 20 mph
@nefelpitou It’s also good to take into consideration, leg design, and proportions as well. Things such as femur length, shin length, ankle structure. Seeing as we do have larger animals that can run even faster due to size, stride length, and leg design; such as ostriches and Carnotaurus. So far the best way to train tell how fast some animals are is fossil trackways; Saturday, these can be altered you to erosion and geographic alterations & changes.
@nefelpitou Secondly: Roadrunners are a bad example of an animal that can run fast without counterbalance. Because Roadrunners DO use their tail feathers as rudders & balance when walking & running.
@@hcollins9941 that's true! I'm aware of them using their tail feathers as counterbalance, but I can't imagine it as effective as an actual meaty tail. But I have noticed, when reading studies (especially older studies, and to be fair I'm far from well read on this subject I've only read a few) that there seems to be somewhat of a reluctance to rely on data obtained from actual extant dinosaurs (birds) rather than models based on anatomical features and conjecture.
