Boverisuchus: The Prehistoric Hooved Crocodile
Вставка
- Опубліковано 2 лип 2024
- Boverisuchus was terrestrial crocodilian who lived during the Eocene. Its ancestors left the water to became apex predators on land after the extinction of the non-avian dinosaurs. Boverisuchus notably evolved large, blunt claws to help it sprint quickly, for which it is nicknamed the "hoofed crocodile". It is also notable for potentially being capable of limited bipedalism.
Thank you to the themattalorian for narrating this video.

CHimerasuchus uploads are so underrated imo. He literally shares dozens of Apex Predators that are so unique on their own. Also crocodylimorphs for the win!
CHimerasuchus and Dr. Polaris both are really underrated
I agree. I really look forward to those wonderful and bizarre apex predators that nobody else details.
2:24 nice try but I know a skull crawler when I see one
Osteoderms completely covering the tail makes me think that they helped hold their tails up more rigidly like therapods. So instead of the spines interlocking like in therapods, the ridigity came from the osteoderms. That could have aided them in bipedal locomotion and generally made them more efficient runners.
11:45 "Mammal-centrism"
That's something I never thought I'd hear but it makes total sense.
It’s almost like the archosaurs were trying to make another Mesozoic period. But the mammals had a leg up on evolution this time.
Thank you for giving crocodillians the rock star treatment they deserve.
Shame that these terrestrial crocodiles are still widely unknown to the public. Being that some of the largest forms could and did (razanandrongobe) compete against theropods. That being said this is another great addition to the collection you have made so far. Keep it up my friend.
Don't forget Fasolasuchus
@@mhdfrb9971 Yeah and along with the other large pseudosuchian predators also.
It's amazing how close we were to encountering giant lion-like crocs in our modern time. Too bad they didn't last long enough for us to witness them alive.
Some of them did survive in Australia long enough to be encountered by ancient humans
Aww yeah
Finally, instead of “first”
A shame that land crocs don’t exist today
With some effort you could evolve a modern gator or croc back into a land croc. It all comes down to filling a role and perhaps putting some into a role which requires more efforts of land hunt would slowly begin the neccessary changes to adapt
I think the exact opposite, we're lucky there are no running crocodiles
Say that like it’s a bad thing 😅
The Cuban crocodile is probably the closest we have.
Thank god
Primeval, my beloved 😭 Gone too soon! …
Great video btw!
I like the narrator’s voice! Very interesting video 😄
This was really interesting. It's so freaking weird I think I will use it for a speculative evolution project. Thank you to the narrator as well.
I have heard of this guy its awsome
Annnnnd that's my day made, nice one chimera
The interesting thing is that Boverisuchus didn’t actually evolve due to a lack of large predatory mammals; mammals started filling megafaunal niches very shortly after the K-Pg mass extinction, and in a few million years there were mesonychids the size of lions hunting pantodonts the size of large ungulates in the Northern Hemisphere.
who is with me on a remake of When Crocs ate Dinosaurs that takes place form the Triassic to Pleistocene. starting with small reptiles living in the shadows of their fellow Pseudosuchians to forms like Crocodylus Anthropophagus and Quinkana.
Probably my favourite prehistoric crocodilian.
I feel bliss as I wake up, drink coffee, and learn about crocodilians
Imagine in the first episode of walking with beast, instead showing animals that don't even existed yet, they showed this
A hypothetical WWB remake would probably have Boverisuchus as the main big predator in the episode instead of Gastornis
Yess. Finally “the horse crock” full infor now released.!🎉🎉🎉🎉❤
Fun fact: Pristichampsus is a dubious genus
Very interesting, thank you so much for the uploads.
Greetings bibia.
The ancient Ian god Sobek came to mind seeing this. Crocodile head on human body.
Please a video on waptia fieldensis which resembles a dinosaur shrimp
I want terrestrial croc to evolve again, and what other crocodilian and crocodylomorphs that coexist or a contemporary of Boverisuchus?
Iberosuchus
In addition to those mentioned in the video, Boverisuchus vorax also coexisted with the alligatoriods Procaimanoidea and Brachyuranochampsa, the latter being a survivor of the Cretaceous Period like Borealosuchus. Boverisuchus magnifrons also lived alongside the alligatoriod Hassiacosuchus and a relative of the false gharial. As a side note, although alligatoriods have been largely confined to the Americas for tens of millions of years (although the Chinese alligator migrated to Asia a few million years ago), during the Eocene they were still present in Europe and Asia.
@@chimerasuchus I thought Asiatosuchus is also a Messel crocodile? Or am I wrong?
@@Evenape A species once assigned to the genus, "Asiatosuchus" grangeri", is found there. However it is no longer considered part of the Asiatosuchus genus, but hasn't been given its own yet.
Would the terrestrial crocs have more lip like flesh around their mouths unlike their water based hiers? Just think of it due to the new debate of other land based dinosaurs. And since the artwork is generally more like a modern croc appearance. Cheers
Croc teeth are on outside of their mouths so it would prob be the same?
Those without aquatic ancestors, like the sebecids, almost certainty had lips. For those like Boverisuchus whose ancestors had lost them, it depends on how easy it was to revolve them.
@Dan they are outside because they are in the water and have no need for lips to keep them wet to negate deterioration. That's why I questioned the territorial versions.
A few of the artworks do depict lips. I bet this is a subject of as much if not more debate amoung land croc researchers as therapod researchers.
@@chimerasuchus Hey man when will you make a video on purusaurus.
The Fabrizio de Rossi art of one standing on it's hind legs reminds me of a tegu running on their hind legs.
Thanks for those high quality videos.
Man this guy just keeps on uploading and I love it! Keep up the good work dude!
Great video and no stupid 30sec ad's to watch at the start 👍..... All the other channels that play any ads that don't have the 5sec skip button then I unsubscribe and don't watch the video.
Another great video 😎
Awesome, thanks. It would be foolish to reject the idea of an endothermic (given some of the plumbing is already there, lying in wait) croc descendant retaking it’s throne on land after the next great extinction…
I was actually thinking of this croc a few days ago!
cool video as always
I love this channel
Great video! A truly interesting animal.
Land crocs would be a serious problem today, especially at the sizes they used to get at.
Thanks a lot for creating & sharing this - highly appreciated. BTW I thought, in a cold environment, an animal that body mass having no fury integument may not even be able to hibernate, no matter how endothermic it may be, which may have been part of Boverisuchus' demise.
Although cooler temperatures were likely a factor, modern alligators are able to enter a hibernation-like state.
@@chimerasuchus Yes! I forgot that. Even under freezing conditions, with their snout sticking out of the ice to enable breathing.
Amazing video! Though I'm surprised you didn't mention Iberosuchus, a much larger relative of the Notosuchian that lived alongside Boverisuchus in Messel.
Love the terrestrial Crocs. You imagine a terrestrial Croc that is big as a Trex or allosaurus
The land croc Barinasuchus was actually within the size range of Allosaurus, although it didn't reach of the size of the largest individuals.
@@chimerasuchus you think there is a terrestrial Croc that hasn't been discovered yet that is as big as the biggest theropod
@@matthewsweeney1593 It is possible, but it would have to be a lot larger than even the most exceptional known land crocs.
@@chimerasuchus true that it'll be the most terrifying but interesting Croc. Have you ever heard of a crocodile cryptid call gbahali in Liberia Africa some say it's a postosuchus
I'm more fascinated by someone else remembering the tv show primeval
Are you going to think of a suggestion making a UA-cam Videos all about Geosaurus (A Marine Crocodile and/or A Sea Crocodile) on the Next Chimerasuchus Next Saturday coming up next?!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️
Meteor strikes
Mammals: wow that nightmare is over. It's a fresh new start!
Reptiles and birds: nope
0:27 CHOMP!
I forget how many heart valves crocodiles have, but, I think it's like 2? 2 and half? Three? ... something that would impact its stamina for running in addition to the ectotherm thing.
I think you are confusing heart chambers and valves, which are merely opening between the chambers. Although most ectothermic reptiles have only three chambers, crocodilians have four like birds and mammals. Additionally, they have a fifth heart valve, which is used to send extra blood to the stomach to aid digestion.
Bitey McBiteface
Basically crocodilians lol
interesting video
Thank you for always making videos filled with great insights.
I have only one request, subtitle...please. Realtime transration is not good for explain such a deep knowledge, but English subtitles can be translated into Japanese well.
I know this is a lot of work, so of course I will not force you to do this. I will continue to support you.
from JP
I already had subtitles made but for some reason they weren't published. Thank you for bringing this to my attention.
@@chimerasuchus You're welcome! Thank you very much!
Boverisuchus is a W creature fr,and so was those video. Can't wait for more like it
Also I wish yall have a great day
Crocodileans/crocodilomorpha and spinosaurids are some of my favorites
Believe it or not.!
The Cuba-crock may have been potential to become the “next Boverisuchus”
So. Please ! Someone please 🙏 export some of them to Australia .
For the algorithm king
The PBS eons video on this creature said its name so many times it got burned into my brain
Man i wish i was like him...
"Looks at boverisuchus"
Land croc! Land croc! Land croc! Yeah!
I'd love a video that just discusses other paleoart lore
Anyone else thought after the 0:12 image, & It had a goofy long back R leg.
Quick question that is completely unrelated to the video in any way:
Did Silesaurus and its relatives have air sacs? Because I heard somewhere that air sacs are ancestral to dinosaurs and their relatives. Honestly, I think you should just do an entire video on air sacs in dinosaurs.
So far there is no evidence that silesaurs had air sacs. However, the same is true for ornithischian dinosaurs, so this has no real bearing on whether or not silesaurs are basal ornithischians.
@@chimerasuchus Thanks for the information. Information about the evolution of air sacs is just really confusing at times. Some sources claim that air sacs were ancestral to dinosaurs and their closest relatives, while others claim that air sacs evolved convergently multiple times. It's an absolute mess.
Modern crocs kill by drowning their prey. A land living croc doesn't have that advantage.
Land crocs don't NEED that advantage to be successful
Noice
What was the largest terrestrial predator excluding dinosaur?
It was probably Faslosuchus, a Triassic pseudosuchian. The largest of the Jurassic was Razanandrongobe and the largest of the Cenozoic was Barinasuchus, both of which were also pseudosuchians. However, none of them are known from complete remains, and the last two are only known from skulls. Therefore their size estimates are based on their smaller relatives.
Were either species different in size?
He reminds me more of a Komodo Dragon even though he looks like a croc.
What speeds was Boverisuchus capable of?
He said 20mph in the video. Probably better to climb a tree than run.
@@patreekotime4578 that’s for modern crocs!
Could a land crocodile still death roll? That's such a deadly adaptation and it still kinda looks like it could do it
With its ziphodont teeth, Boverisuchus wouldn't really need to death roll anymore. Although I know of no research relating to whether or not Boverisuchus could still do it, the vertebrae of the later land croc Mekosuchus found it had probably lost that ability.
Speedy crocs battle; Boverisuchus, Kaprosuchus and Quinkana
Those skulls have visible lines of foramina where you would expect lips.
didn't say how fast it could run or when it died out
Does suchus mean crocodile?
Yes.
What habitat did it lived in?
Tropical forests.
I really did love all the monsters on Primeval that were just a dude.
Before i dive into the video:
Isn't the thumbnail clickbait?? Cuz boverisuchus is clearly not hooved.....
It is actually nicknamed the hooved crocodile. While its claws were not as specialized as the hooves of horses or deer, they do resemble more primitive hooves.
@@chimerasuchus ah ok, it's just that hooved animals stand on nails alone while other animals are either digitigrades or plantigrades, so I was confused as to why it was called hooved.
They went extinct when the T-rexes started driving cars into the climates.
Quick question: How did they exist on both continents of Eurasia and North America when the continents were too far apart and the land bridges can not explain it since there isn't evidence of reptilian or crocodilian Interchange from the Bering Land Bridge.
North America was connected to Europe and possibly Asia by the Thulean North Atlantic Bridge. Also, although cold temperatures were a barrier to most ectotherms in the later Pleistocene, the Chinese alligator is thought to have crossed the Bering land bridge just a few million years ago. In any event, such temperatures were not a problem during Boverisuchus's time, and it may not have even been an ectotherm.
Croakerdhellians
Hey chimerasuchus I would like to inform you that boverisuchus is a crocodyliform and not a crocodilian
Terror birds just weren't on the list
He didn't run out of prey. That animal never ran out of prey. It evolved into modern crocs and lizards. Climate change didn't kill them off. It caused them to grow in a different direction.
Lizards are not closely related to crocodilians, and the ancestors of all three groups of living crocodilians were already around before the end of the Cretaceous, long before Boverisuchus's extinction.
babies eggs don't forget adults could probably coupe with cold nights what does cold do to the sex of the hatchlings and no one likes mice in the nest mound AK
I KNOW THE CROCODILIANS WERE NO MATCH FOR ANDREWSARCHUS ! 😊😊😊
Please man the ai shit makes us all miserable.
What AI?

Prehistoric nonsense
All I know is Crocs are build/evolve to survive in someway and birds and crocs are related meaning Dinos are some what closer to crocs. Crocs are majestic.
"All I know is Crocs are build/evolve to survive in someway"
- all organisms are, that's what evolution and natural selection does
"and birds and crocs are related meaning Dinos are some what closer to crocs"
- what?! Is that saying dinosaurs are closer to crocs than to birds? They aren't. Birds and _other_ dinosaurs share a closer common ancestor than to crocodilians, indeed birds evolved from a dinosaur lineage, and _are_ dinosaurs
