Deinosuchus didn’t live with Tyrannosaurus, nor would it prey on such an animal, large prehistoric crocodilians really are overestimated. Deinosuchus was a predator, and predators kill to survive, which means it would be hunting easy meals, which certainly doesn’t include dinosaur the same size as it that also has very good chances of escaping or fighting back and killing it. That’s like depicting a modern American alligator hunting a black bear on land, it honestly just seems like a way to get people interested in underrated animals.

That percentage is too low, quit dreaming. Most ancient animals have been recorded

[@julianeder4699]

​@@Woronoa This may be true for animals that existed relatively close to the present day (sabertooths, mammoths...) but once you turn the clock back just a few million years further you will notice that remains become less common and more fragmented thanks to stuff like erosion the shifting of the tectonic plates destruction of the source material by human hand... A well studied example for that would be T-Rex its estimated that about 2-2.5 billion of them existed throughout its 2.5 million year reign yet we have uncovered only about 100 of them with only about 40 of them being somewhat complete. Go back another 30 million years to the time when Giganotosaurus Mapusaurus and Carcharodontosaurus walked this earth and the number of recovered fossils shrinks down to single digits with the remains typically consisting of nothing but a few teeth and the occasional femur.

[@william3100]

​@julianeder4699 but in the few remains we have found, we already know a lot about them. So I doubt we'll find something completely crazy and perception overturning like an ancient intelligent dinosaur civilization or something. Most things we haven't found will be things we can predict would exist or something at least just a little bit unexpected but not earth shattering! There's is much less of a chance of that happening. The percentage is most definitely too low. It's not all just guess work or bring completely in the dark. We're not in the medieval ages or 40s any more, and things like spinosaurus and discoveries concerning it are very rare and not indicative of most things. You underestimate how much we know now.

[@julianeder4699]

@@william3100 Last year alone we discovered 140 extant animals that have never before been described. Truth is we dont even know all the animals that walk our earth at this present moment let alone the countless creatures that roamed the earth in the past 3.7 billion years. Granted most of them would be microscopic while others simply didnt have any bones that made fossilization possible but every year we uncover atleast one new giant from the past (the swiss tyrant for example in 2023) Its estimated that less than 1 in 10000 bones will fossilize and the odds of us stumbling across said fossil are even lower so us knowing 1% of all animals that ever existed is already a quite optimisitc estimation Im not sayin that we will find anything that shatters all our believes and understanding of these creatures nor did i ever mention anything about intelligent dinosaur civilizations... the thought of that would be silly. Im simply stating that any ''biggest predator'' we know of today will most likely be dethroned in the next 50 or so years by some other carnivore we simply didnt yet unearth.

It's very, very likely that for the majority of extinct species, we will never find any evidence they once existed.

I can't even comprehend how someone could come to the conclusion that this thing had a "fairly weak bite for it's size". I mean, one look at the skull should tell you otherwise. Deinosuchus was a monster of an animal, and I would not be surprised at all if it was indeed the apex predator of the regions it got the largest in. They certainly would have made any body of water within their range a very risky prospect.

[@ericknorskr8568]

About the bite size. It's snout is relatively not long compared to its skull size . and bite power is Long=strong

[@doomboi789]

​​@@ericknorskr8568 that isn't how bite power estimation works. Shorter and more robust snouts can also produce immense bite forces. Bite forces in crocodilians are typically estimated via potential muscle attachment points on the jaw, such as the retroarticular process at the back of the lower jaw or the space around the base of the jaws, not the length of the snout itself. Deinosuchus skull also yields even more evidence of a powerful bite, due to both the incredibly tough teeth and the immensely robust skull. Also, are we looking at the same animal here? A Deinosuchus jaw is far from short, it's proportionately much longer than any other alligatorid.

[@vault_dwelIer]

Scientists do this a lot. Creature X has massive claws? Only a matter of time before someone concludes they were too brittle to be used as claws. Creature Y has gigantic armored plates on on its body with an enormous thagomizer? Well some one will come to the conclusion they couldn't possibly be used as defense or offense. Arguably these ideas ultimately give us better understanding when they're refuted.....but a lot of them fail the immediate common sense check.

[@seanmckelvey6618]

@@vault_dwelIerjust because something can be used for one thing doesn't mean it can't be used for other purposes. I agree, science can often get too absorbed with nitty gritty details and forget that, in the case of paleontology, we are talking about what were once living, breathing animals.

One interesting thing to note about crocodiles in general is that sizes can vary immensely between individuals and also they grow seemingly until they die. So making a maximum size estimate would be difficult and chances are this thing could get as big or even bigger as the maximum estimation given it was a gifted individual.

[@air9music]

I think it'd be helpful at 4:26 to clarify what "8 times smaller" means - an average saltwater croc weighs around 400-700 kg and has a length of around 4m so both the length and the weight are much more than 1/8th that of a Deinosuchus, probably around 1/3rd. Still puny, but not "8 times smaller" puny.

In all the scientific papers, it is claimed that Purrusaurus had teeth with an absolute maximum length of 5 cm (or 2 inches).

purussaurus as mentioned in the video, was only slightly smaller

Imagine going fishing and seeing this in the water 💀

Pretty sure if u see it in the water its already too late lol

Exceptional 😮Many thanks for sharing ☺️

Informative lesson!Thanks!😊

Thanks for my suggestion :D

This video is the reason why Deinosuchus is my favorite crocodilian.

[@trvth1s]

Likewise, the largest predator today that can walk on land is a salt water crocodile, which can get larger than polar bear. With that said, crocs are subaquatic so it's a bit of an unfair comparison.

[@Dr.Ian-Plect]

Well, changing the wording to 'that can come onto land' makes it something else.

[@trvth1s]

@@Dr.Ian-Plect true, but on land a crocodile or a seal isn't much if a threat unless you intentionally run into them. I wouldn't compare them to a siberian tiger hunting buffaloes

[@Dr.Ian-Plect]

@@trvth1s I'm not sure your reply relates to what I meant, I'll just restate my thinking. I meant there is an animal larger than a saltie that can come onto land, and it's a predator. Indeed _it_ is _the_ largest predatory animal (or animal whatsoever), that can freely come onto land.

[@trvth1s]

@@Dr.Ian-Plect what is it? An elephant seal?

[@Dr.Ian-Plect]

@@trvth1s Yes! Specifically the southern species. I think that confirms your reply misunderstood what I was getting at.

[@pizzatime7431]

There's no way a crocodilian has a bite force so weak relative to it's size

[@isaiahjones8668]

Deinosuchus is amazing, crocodiles were my favorite animal but when I discovered the deinosuchus and other prehistoric crocs I was reasonably astonished. Also its really cool to me that crocodilans hunting strategies have been the same all these years.

[@petergianarakos4439]

Great vid! Very informative and interesting. Thanks!

[@roachman03]

Your ability to pronounce all these scientific names, 👌🏾 that is art.

I know Joey didn’t like me keeping that Schleich toy but resizing Dunkles bony one is nuts

[@kronotic]

Spinosaurus was the largest predator during the cretaceous.

[@kronotic]

@prodigyshark1204 Yes.

[@kronotic]

@prodigyshark1204 Spinosaurus is the largest land predator of all time. Both in size and weight. You must get your information from movies, do a little research.

[@tristandaries1129]

Realistically, it actually makes sense that it’s bite would be lower than expected for its size. After it reaches a certain point of being able to break almost any bone, there’s no reason for it to go higher, 18 000 Newtons and 100 000 Newtons could kill something pretty equally, except one would require much more energy to make the muscle denser

Crocodiles for me are the dino of our Time

[@justino9042]

😂 uff that was a close one 11:31 that was tricky.

[@bigred8438]

from my observation of crocadillians today. It seems they may simply have to have had a bite force that allowed them to hold on to prey long enough to drown it rather than tear strips or chuncks of it while still alive. Crocodiles in Australia still drown their prey, but use a tactic called a "death roll", (oops you just mentioned that) in which they simply grab prey, then twist their body over and over and over to disorientate their prey as they take it under water.

[@prayasdash]

I kinda think the Purussaurus was slightly larger than the Deinosuchus

[@davidh7300]

Put it this way-if he latches on to you, the death roll is gonna hurt. If he doesn't just gulp you down after a good crunch.

[@MichaelSmith-ns8ow]

My thought’s that there’s a missing massive sea Crocodile probably twice the size of these creatures. However, I think the biggest predator was a Plant or a sea Jellyfish.

[@GigaToad-wc8kp]

I like the theory that basically states smaller but more effective predators were able to put compete it.

Great vid!!!
