It’s actually more likely that dinosaurs were an opportunistic prey item for Deinosuchus rather than a staple, seeing as pretty much all semiaquatic crocodilians feed primarily on aquatic prey.
Actually most crocodilians today primarily hunt mammals, the smaller crocs feed on fish though. When they're in their bigger sizes they need bigger food, I.E. Mammals.
@@samuraispeltwrong no living crocs primarily hunt mammals: the idea they are is a myth perpetuated by media ONLY showing that behaviour and ignoring that 80% of, say, a Nile croc’s diet is made out of fish. Yes, bigger crocs need bigger food but bigger food doesn’t have to be mammalian
@@bkjeong4302 so you telling me this camper with the worst vibe check in the animal kingdom uses its vibe check to hunt fish? Sorry that's not it chief
@@samuraispeltwrong why would it not? Fish are more common in/around water than land animals after all. A croc has to wait for a land animal to come for a drink to grab it, but it can find fish swimming too close to its jaws much more easily and it’s not going to pass up the chance.
Ever since I started looking into prehistoric animals besides dinosaurs, the crocodilian family has held a special place for me. Deinosuchus especially. I wish we had a complete skeleton to see what other unique traits they had besides their massive size.
crocs and their close relatives really are amazing. having excisted long before the non avian dinosaurs. and long after. they are for sure one of the most succesfull animal families in earths history. for sure when it comes to reptiles. they used to be so mich diverse than the 27 plus/minus extant species we know of.
@@theflyingdutchguy9870 I know, right?! I get this sense of endless endurance from the entire family. The archosaur family is almost as old as life itself and very nearly became the most predominant form of life in every age. If things had gone just slightly different, they could have outcompeted the dinosaurs, then after the KPg, they nearly outperformed mammals as well. And in every age, they've fielded apex predators and tons of diversity. Almost like a living fossil, but better.
Deinosuchus most likely preferred sea turtles, as they were far more common than dinosaurs and more easily accessible. This also explains the heavy wear on their teeth, as turtle shells are much tougher than dinosaur bone.
Only makes sense that the king of all crocodilians lived at the same time as the biggest menace to ever walk the earth, did too. Competition breeds greatness
@@GODEYE270115 My G... Purussaurus is able to perform a DEATH ROLL lmao And second it depends of Deinosuchus's estimate because of how controversial and debatable it is for specimen AMNH 3073. Some have resulted in a range of 9, 10 , to 13 meters so it also changes within those too. Same situation for Sarcosuchus by some.
The idea that dienosuchus didn't slow down in terms of growth is both so cool and so intimidating lol, plus the implications of gigantothermy are truly fascinating! phenomenal video as always Chime! Loved it from start to finish and I can't wait to see what comes next! Keep up the awesome work!

Why not collect crocodile and alligator DNA and have the prehistoric crocodiles first for a zoo just to get a better idea of how they behave or act in the wild. That way we can get archeosaurs to evolve back into existence as well
Good video. deinosuchus was one of the most interesting and amazing crocodilians. I didn't know that there was a possibility that third species existed. but if it really is a third species that is interesting as well.
Yesss, I was hoping you'd compare Deinosuchus and Purussaurus, what an incredible animal. Would you say Puru and Barinasuchus were the largest predators in the Cenozoic?
Although the dinosaux was much larger than any modern crocodile or alligator, as the size of the largest adult was 10.6 m (35 ft) in total length, its overall appearance was very similar to its smaller relatives, it had large, strong teeth designed for crushing, and its back was covered with thick hemispherical bone skin, and a study determined that the dinosox lived for up to
The largest species of Deinosuchus is D. hatcheri and it was estimated by Fadeno to have been 14.12 meters long and 15,417 kilograms. Purussaurus on the other hand is 10 meters and approximately 8 tonnes according to a DM conversation with me and Fadeno (he gave the 8 tonne figure)
@@ferociousrazordino3581 Purussarus mass is kinda controversial cuz there is no vollumetric analysis (it makes sense cuz its poorly described) so the mass is mostly scaled up from todays crocs though 8t is too much
It depends on who gets the first bite in. If this large croc manages to get the first bite on the king T Rex, then yes it would have toppled the king. But if T Rex managed to get the first bite, especially on its head or near the jaws, this croc would have lost. Excellent video by the way, keep up the good work 🤗
Aww yes, I was wondering when these lorge bois would be coming up. And an appropriately extra lorge video too. Though what an appalling indignity the Alligatoroids have suffered. Imagine your lineage produced two titanic predators in two different geological periods; but you are born to a post-nerf branch of the family that's well... _relatively_ big. Also, you are being farmed for your hide. Descended from hegemons, raised to be a handbag.
The problem is, being a "titanic predator" means that you're immediately on the chopping block the minute the extinction event hits, because apex predators and the biggest and baddest life forms around are hyper specialized. Smaller crocs could survive the Triassic Extinction and the Cretaceous Extinction (and were basically unaffected by the events that signaled the end of the Jurassic, and the Aptian Extinction, and the Cenomanian-Turonian, and all the minor extinctions that have happened since the Cretaceous), but the larger ones were at massive risk the minute the environment shifted too far. It's not impossible that in a hundred million years, long after we're dead, they get big again, and when they do the big ones will eventually die again. That's just how these things go.
I saw a massive SW croc at the crocodile zoo in Broome, West Oz. It was over 5m long and was removed from the wild after it killed 3 horses. As it climbed out of its pond to be fed the crowd literally went silent in total awe. I can’t imagine what these extinct giants must have been like.

There are few predators that seem to have evolved a near optimum form that is not highly specialized. Where form itself is optimized without the need to augment form with things like superintelligence.
Ok so since no one else mentioned it: David Schwimmer is also the name of the actor who played Ross in the sitcom Friends; the character Ross was a paleontologist. Fun stuff, eh?
Great video as ever. I imagine smaller deinsuchus would have lived in rivers and freshwater marshes and cypress swamps. Otherwise it really seems much like we see with esturine crocodiles the adults living in the estuaries and ranging up into freshwater and also into the sea. Between the humongous turtles, deinosuchus, mosasaurs, elasmosaurs, large sharks and xianocaphus I'm kust sorta a little bit disapointed that we don't currently have a seaway as hectic as the interior seaway!
Though I'm a Smilosuchus fan, I do love Deinosuchus but one thing I also want to add is that Deino technically would be killed by a spino since it wasn't too movable but I could still be wrong tho. But either way this video was absolutely amazing and I wish yall are having a great day
Remember Deinosuchus wasn't invincible, legit it's weakest part was its belly, yes definitely a Deino can clap a Spino but for me don't completely underestimate Spino cause it is a taller after all and would have a better reach on its underbelly or neck given the chance

@@rodrigopinto6676 They’re both 40ft long so they’re most likely going to weight the same. I understand Tyrannosaurs are absolute units but so are crocodilians.
Great show! I'm glad there's a vast gulf of time between that monster and me. It's unsettling to feel snack sized, and a bit offensive to know I wouldn't make a very filling meal LoL.
02:56 Lemme get this straight, there's a David Schwimmer who's not an actor but a real paleontologist and a David Schwimmer who is an actor and a fake paleontologist? Life is rad. Supersymmetry is real.
9:42 Well no.The skeleton of the biggest sarco is 50 year old the deino that Fadeno calculated is more than 90 so if sarcos could reached that age its very likely that some individuals were at least the size of Scotty 10.6 tons estimate
I wish ranks and clads would be forced to be the same. 2 species to each genus for example the genus Alligator. These could always be revised as clearer relationships were made. Having three or more species in a genus or the same for genera to a family just adds to the confusion.
I think we are underestimating the size of Deinosuchus. There were probably some crazy outliers back then. With no humans to stick there noses in, I’m sure some got gigantic HUGE. 40 feet doesn’t seem like that much of stretch for an outlier deino imo.
Great video! Interesting to think about Deinosuchus beginning as normal-sized hatchlings, but their environment and prey were such that both could support a predator that essentially never stopped growing rapidly. By the way, 16:30 the western interior seaway was not continental drift/rifting, but rather due to the crust there 'sagging'- through some combination of the Western Cordillera crustal thickening weighing it down, compression due to the subduction of the Pacific plate under North America, etc. Not an expert on it tho
The picture with the deinosuchus skull next to a small ceratopsian I saw in person a couple weeks ago in San Antonio. They also at that time had Scotty the T-Rex on display. It was really cool to see these Goliath’s in person.
Great video, from someone who has done amateur research about Deinosuchus for over 10 years. You said that Deinosuchus may have started out as one species and then got split in two species because of the W.I.S. coming through. However, the W.I.S. was around far earlier than the first known Deinosuchus specimens. What are you suggesting, then?
Deinosuchus is a crocodilian of the extinct family Deinosuchidae, an extinct family of stem-alligatoroids, meaning there closest living relatives were alligators (family Alligatoridae) and caimans (family Caimanidae), other members of the extinct family Deinosuchidae include Protoalligator, Leidyosuchus, Tadzhikosuchus, Listrognathosuchus, and Diplocynodon, Deinosuchidae is basal to the clade Globidonta, which includes two other stem families of alligatoroids being Ceratosuchidae (includes Ceratosuchus, Navajosuchus, Strangerochampsa, and Brachychampsa) and Orientalosuchidae (includes Dongnanosuchus, Eoalligator, Jiangxisuchus, Krabisuchus, and Orientalosuchus) and the crown alligatoroids being the families Alligatoridae (Alligators) and Caimanidae (Caimans).
Butch the Tyrannosaurus rex went for five days without water at 100 degrees in the shade until he saw a beautiful pond, he bent down and took a drank from it. Suddenly, three deinosuchus lunged out of the water, one of them bit Butch on the face, giving him a scar. Butch was not ready for dying that day, so he bit one deino in half, tail whipped the other and drowned the last one in his own blood (meaning he ate it), getting one of its teeth stuck to his gums as a souvenir. From: The Good Dinosaur.
@@rodrigopinto6676 nah. It might've been bigger as suggested by David Schwimmer and Thomas Holmes. You can't deny that it probably rivalred T. rex in size.
crocodillians are so tough to place because the hatchlings and adults can look so different. like when you look at an american gator hatchling it looks more like something like a spectacled caiman.
im no expert on what or if oxygen levels are related to growth but in my humble speculative opinion i think it was able to grow that large just like most dino's with the fact that around the time when deinosuchus was alive, the oxygen levels in the air back then were way higher than what it is now, today i believe it was like 21% oxygen if im not mistaken, but back then it was more like around 38 to 43% or something, so crocodillians today cant grow as large as deinosuchus maybe because of this Again i'm no expert in this, i've just heard theories and whatnot over the years
The purusaurus was another crocodalian placed back to the Miocene period wich was 3million years ago. And known as the biggest crocodilians to have ever lived. This did not live with dinos. Purusaurus was massive croc having a bite force powerful than a trex. Purusaurus went extinct due to short of food. Purusaurus had such a round head not like sphere. Purusaurus could probably live up to 60-80y old. They can reach up to almost 40ft they can only reach up to 37-39ft
Deinosuchus hatcheri is largest crocodilian ever they can grow 14'3 meter and weight 14 ton they largest crocodilian ever Their fossils are only the backbone of the head to tail that is measured 14 meter
Why does the Royal Tyrrell Museum have their comments section completely shut off?? There's some really good discussions on some of these type of awesome videos. Doesn't matter .....come visit Drumheller Alberta anyway ,it's an amazing small town and the museum absolutely kicks ass. Plus the local coal mining history is awesome.
Deinosuchus had a bite of about 20,000 PSI and a T-Rex had a bite of over 13,000 PSI, so Deinosuchus' bite wasn't twice as strong. The most powerful bite in the animal kingdom (including extinct animal) belonged to the Megalodon, it had a bite force of about 40,000 PSI
It can still be argued that puru is larger as the largest estimated size as deino is 40 and puru can be larger than that. So the deino is most likely not the strongest nor the king.
What about its reproductive habits? It didn't talk about how Deinosuchus raised its young. Even if it did most likely do it the same way modern crocodilians.
That would be a hell of a battle to see between a Deinosuchus and a T- rex , I guess it would have to happen on dry land to be fair because in the water Croc would have too much of a advantage, The T Rex would have speed , agility on its side and the Croc would have a low center of gravity forcing the T Rex to limit what kind of attacks it could do and the T Rex would also have to worry about a tail swipe from the Croc that would knock it off its feet and make Vulnerable to the Croc coming in, Bite force and damage would be about equal, Unless the croc had a tougher hide than a T Rex that would resist the Teeth of the T Rex, The T Rex would have a advantage of what kind of bites it could deliver such as to the neck, legs or midsection of the Croc, while the croc would be limited to attacking the legs or tail of the T Rex since it is so low to the ground, Then again once the croc locked on to one of the legs of the T rex and did a death roll the T Rex would be crippled and helpless against further attacks
It would probably got down similar to how lions and crocs interact on land. They just harass the croc until it swims back into the water. Crocs don’t want a land battle and deinosuchus would have been the same. Crocs even flee from humans when on land since the water is their natural element.
fun fact even tho most estimates put them around 12 meters or 40 feet ,there have been also some speciments reaching 15 meters and because we know so little and have little amount of skeletons they could be even larger then that
When I first watched this I thought with such a large size it would only rule the waters only coming out to mate and for females to lay eggs but then I hear it came on land and walked around with ease despite its weight, my heart dropped.
What would happen if you took a large older croc and started giving blood transfusions from much younger crocs who are in that growth spurt? Would they start growing again?
You think you can also make another UA-cam Videos about more Crocodilian Species such as Dakosaurus or either Toyotamaphimeia machikanensis coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
Certainty. Toyotamaphimeia is acutally planned to be the next video about an semi-aquatic crocodylomorph, that several other videos are planned to come out before then.
Impressive but more attention should be placed on Purrusaurus. It was practically the same size but lived until 8mya, essentially making it the top global apex predator.
megalodon actually had the strongest bite force in the animal kingdom, its bite force was estimated to be about 40,000 and Deinosuchus was estimated to be 20,000

Great show! I'm glad there's a vast gulf of time between that monster and me. It's unsettling to feel snack sized, and a bit offensive to know I wouldn't make a very filling meal LoL.

9:42 Well no.The skeleton of the biggest sarco is 50 year old the deino that Fadeno calculated is more than 90 so if sarcos could reached that age its very likely that some individuals were at least the size of Scotty 10.6 tons estimate
Correct, this UA-camr it’s a t.rex=hater.
Really enjoyed this one ! Thank you 😊!
I'm loving this crocodile/alligator theme you've got going lately
I wish ranks and clads would be forced to be the same. 2 species to each genus for example the genus Alligator. These could always be revised as clearer relationships were made. Having three or more species in a genus or the same for genera to a family just adds to the confusion.
Loved this video on the king of crocodilians! ✊
Deinosuchus was smaller than Tyrannosaurus rex.

I think we are underestimating the size of Deinosuchus. There were probably some crazy outliers back then. With no humans to stick there noses in, I’m sure some got gigantic HUGE. 40 feet doesn’t seem like that much of stretch for an outlier deino imo.
Great video! Interesting to think about Deinosuchus beginning as normal-sized hatchlings, but their environment and prey were such that both could support a predator that essentially never stopped growing rapidly. By the way, 16:30 the western interior seaway was not continental drift/rifting, but rather due to the crust there 'sagging'- through some combination of the Western Cordillera crustal thickening weighing it down, compression due to the subduction of the Pacific plate under North America, etc. Not an expert on it tho
Sarcosuchus is not a crocodile, it may look like one but it’s actually a close cousin of crocodiles.
Yep
Crocodilians are the most amazing animals that walk or walked this Earth. Love to see them butcher their prey.
The picture with the deinosuchus skull next to a small ceratopsian I saw in person a couple weeks ago in San Antonio. They also at that time had Scotty the T-Rex on display. It was really cool to see these Goliath’s in person.
Great video, from someone who has done amateur research about Deinosuchus for over 10 years.
You said that Deinosuchus may have started out as one species and then got split in two species because of the W.I.S. coming through. However, the W.I.S. was around far earlier than the first known Deinosuchus specimens. What are you suggesting, then?
A vídeo on purusaurus would be great too
Awesome, another well done video.
I like.
Greetings bibia.
Deinosuchus is a crocodilian of the extinct family Deinosuchidae, an extinct family of stem-alligatoroids, meaning there closest living relatives were alligators (family Alligatoridae) and caimans (family Caimanidae), other members of the extinct family Deinosuchidae include Protoalligator, Leidyosuchus, Tadzhikosuchus, Listrognathosuchus, and Diplocynodon, Deinosuchidae is basal to the clade Globidonta, which includes two other stem families of alligatoroids being Ceratosuchidae (includes Ceratosuchus, Navajosuchus, Strangerochampsa, and Brachychampsa) and Orientalosuchidae (includes Dongnanosuchus, Eoalligator, Jiangxisuchus, Krabisuchus, and Orientalosuchus) and the crown alligatoroids being the families Alligatoridae (Alligators) and Caimanidae (Caimans).
"the extinct family Deinosuchidae, an extinct family of..." why'd you feel the need to mention it twice?

"Only a crocodile full"
**Pulls out comically large crocodile**
Butch the Tyrannosaurus rex went for five days without water at 100 degrees in the shade until he saw a beautiful pond, he bent down and took a drank from it. Suddenly, three deinosuchus lunged out of the water, one of them bit Butch on the face, giving him a scar. Butch was not ready for dying that day, so he bit one deino in half, tail whipped the other and drowned the last one in his own blood (meaning he ate it), getting one of its teeth stuck to his gums as a souvenir.

Do you think T. rex made a low growl like crocodile does under water?
Possibly 13 meters?! That's almost 43 feet!
No only 11-11,5 meters long.
Up to 45 feet or over 14 meters!

A few months ago I was in Hill City, SD. They have an old school gym turned museum that had skulls from both a deinosuchus and a sarchosuchus.
The only creatures that tyrannosaurids would fear, are massive swamp monsters like crocodiles.

Great piece of Croc!!!
crocodillians are so tough to place because the hatchlings and adults can look so different. like when you look at an american gator hatchling it looks more like something like a spectacled caiman.
im no expert on what or if oxygen levels are related to growth but in my humble speculative opinion i think it was able to grow that large just like most dino's with the fact that around the time when deinosuchus was alive, the oxygen levels in the air back then were way higher than what it is now, today i believe it was like 21% oxygen if im not mistaken, but back then it was more like around 38 to 43% or something, so crocodillians today cant grow as large as deinosuchus maybe because of this
Again i'm no expert in this, i've just heard theories and whatnot over the years
Oxygen levels at that point were nowhere near 30+%: at most they were slightly higher than today, if not lower.
I'm not an expert however cold blooded retiles and relatives higher temperatures allow larger size.
@@bkjeong4302not true at all what where did you get that from

The purusaurus was another crocodalian placed back to the Miocene period wich was 3million years ago.
And known as the biggest crocodilians to have ever lived.
This did not live with dinos.
Purusaurus was massive croc having a bite force powerful than a trex.
Purusaurus went extinct due to short of food.
Purusaurus had such a round head not like sphere.
Purusaurus could probably live up to 60-80y old.
They can reach up to almost 40ft they can only reach up to 37-39ft
8million years in the late Miocene period.
Deinosuchus hatcheri is largest crocodilian ever they can grow 14'3 meter and weight 14 ton they largest crocodilian ever Their fossils are only the backbone of the head to tail that is measured 14 meter
Why does the Royal Tyrrell Museum have their comments section completely shut off??
There's some really good discussions on some of these type of awesome videos.
Doesn't matter .....come visit Drumheller Alberta anyway ,it's an amazing small town and the museum absolutely kicks ass.
Plus the local coal mining history is awesome.
cool my favorite crocodilian Deinosuchus
Great video!
Deinosuchus had a bite of about 20,000 PSI and a T-Rex had a bite of over 13,000 PSI, so Deinosuchus' bite wasn't twice as strong. The most powerful bite in the animal kingdom (including extinct animal) belonged to the Megalodon, it had a bite force of about 40,000 PSI
It can still be argued that puru is larger as the largest estimated size as deino is 40 and puru can be larger than that. So the deino is most likely not the strongest nor the king.
Hearing that a caiman was once the size of a deinosuchus just makes them getting bullied by otters and jaguars all the more sadder
What about its reproductive habits? It didn't talk about how Deinosuchus raised its young. Even if it did most likely do it the same way modern crocodilians.
Great drawings man
I really love it ! Thanks ❤
That would be a hell of a battle to see between a Deinosuchus and a T- rex , I guess it would have to happen on dry land to be fair because in the water Croc would have too much of a advantage, The T Rex would have speed , agility on its side and the Croc would have a low center of gravity forcing the T Rex to limit what kind of attacks it could do and the T Rex would also have to worry about a tail swipe from the Croc that would knock it off its feet and make Vulnerable to the Croc coming in, Bite force and damage would be about equal, Unless the croc had a tougher hide than a T Rex that would resist the Teeth of the T Rex, The T Rex would have a advantage of what kind of bites it could deliver such as to the neck, legs or midsection of the Croc, while the croc would be limited to attacking the legs or tail of the T Rex since it is so low to the ground, Then again once the croc locked on to one of the legs of the T rex and did a death roll the T Rex would be crippled and helpless against further attacks
Most researchers agree that D.suchus had a stronger bite than even the tremendous bite forces of T-Rex.
It would probably got down similar to how lions and crocs interact on land. They just harass the croc until it swims back into the water. Crocs don’t want a land battle and deinosuchus would have been the same. Crocs even flee from humans when on land since the water is their natural element.
fun fact even tho most estimates put them around 12 meters or 40 feet ,there have been also some speciments reaching 15 meters and because we know so little and have little amount of skeletons they could be even larger then that
When I first watched this I thought with such a large size it would only rule the waters only coming out to mate and for females to lay eggs but then I hear it came on land and walked around with ease despite its weight, my heart dropped.
What would happen if you took a large older croc and started giving blood transfusions from much younger crocs who are in that growth spurt? Would they start growing again?
If we take the growth regulating fen from tigers and put it in Nile croc or salt croc who’s know how big that would get
D. riograndensis had to contend with several genera of Tyrannosaurs in Laramidia.
Peoples: Spinosaurus is the king of the rivers
Deinosuchus: Huh
