This channel makes educational videos on paleontology, with a focus on Pseudosuchia (the group of reptiles crocodilians are a part of) and reptiles from the Triassic Period, the first (and easily most bizarre) period of the Mesozoic Era. It also regularly makes videos about dinosaurs and early synapsids and occasionally other related topics. In general, this channel tries to give the spotlight to obscure creatures rarely given attention elsewhere.
Tiarajudens: Saber-Toothed Permian Proto-Mammal
Tiarajudens was a distant relative of mammals notable for its long, saber-teeth. Rather than hunt with them, as was done by saber-toothed cats such as the famous Smilodon, Tiarajudens is thought to have used its saber-teeth as display devices and to fight rivals of the same species. Indeed, unlike other prehistoric saber-toothed creatures, Tiarajudens was a herbivore. It lived in Brazil during the middle of the Permian Period, tens of millions of years before the rise of the dinosaurs, and when proto-mammals like it were the dominant terrestrial fauna.

Ibirania: The Exceptionally Small Sauropod Dinosaur From Late Cretaceous Brazil
zhlédnutí 28KPřed 7 měsíci
Ibirania was an exceptionally small sauropod dinosaur, with an estimated length of only 5.7 meters. Whereas most sauropods of comparable size lived on isolated islands, Ibirania lived on mainland South America. Its discovery has shown that Sauropoda was much more evolutionarily dynamic than previously thought. Thank you to the themattalorian for narrating this video. Sources: www.researchgate.n...
Typothorax: The Largest Of The Armored Aetosaurs

Typothorax was a heavily armored, wide-bodied reptile that lived before the reign of the dinosaurs. It is the largest known member of Aetosauria, a clade of predominantly herbivorous, terrestrial reptiles distantly related to crocodilians. Although Typothorax was the second aetosaur discovered, it has only been within the last decade that fossils complete enough for a full reconstruction have b...
Pseudosuchia: An Overview Of The Prehistoric Relatives Of Crocodilians

Pseudosuchia is the clade consisting of crocodilians and all the extinct reptiles more closely related to them than to any living species. Beneath this formal definition lays a once dynamic and diverse group reptiles that were far more than simply minor variations of today's crocodilians. Pseudosuchia is one of the two branches of the clade Archosauria, the ruling reptiles. This is the same cla...
Sarcosuchus: The Prehistoric Super Croc

Sarcosuchus was a massive relative of crocodilians which lived in what is now North Africa and South America during the Early Cretaceous Period. This "Super Croc" was so large that it was not only capable of hunting dinosaurs, but was also the largest known predator in its environment. However, young Sarchosuchus had long, thin jaws specialized for catching fish, allowing them to avoid competin...

Shunosaurus was a small sauropod dinosaur from Middle and Late Jurassic China. It is notable for possessing a small club at the end of its tail, which like the clubs of the ankylosaurids, was used to ward off attacking theropods. Numerous Shunosaurus skeletons have been found, many of them complete, so despite being one of the strangest sauropods, it is also one of the best understood. Thank yo...

Carnufex carolinensis, whose name means “Carolina Butcher”, was once the top predator in what is now North Carolina 231 million years ago during the Triassic Period. Carnufex was been critical in understanding the shift in crocodilian evolution from early psudesuchians like the rauisuchians to the smaller, more derived sphenosuchians, which would give rise to the later crocodylomorphs (includin...

Your mom gave me some pseudosuchia…

Awesome!!!!
I would keep it as a pet
a lot of pure lies presented as fact in this video but overall i think its a good vid. well done lad!
There's a pretty cool scene in PBS The Dinosaurs! Episode 3 (1992), where Herrerasaurus eats a Thrinaxodon, kill a Rhynchosaur and get chased off by Saurosuchus.
Love these videos they are so Interesting
the machimosaurus rex was found in 2016, tunisia💀💀💀💀
Sounds like a Phil Collins song.
Of course the Cuban crocodiles work together ✊❤✊
That’s what I called my ex mother-in-law’s but now I know better
That moment when the dinosaurs in Jurassic Park look closer to these mother truckers than actual dinosaurs 💀
thanks for sharing, rlly enjoy watching your videos
I wonder what Daemon Targaryen would think of this dinosaur.
Hey, I hope you are fine and will make soon new videos
What is the genetically closest modern animal of Smilosuchus?
Either crocodilians (ironic given how many of their superficial similarities are the result of convergent evolution) or a tie between them a birds.
Absolutely NOT the closest living extant relatives. They are the birds. Stop spreading misinformation.
Cladistically, birds are dinosaurs, so they are not just mere relatives of the group.
This video should have had the Crocopocalypse image by Darren Naish included at some point.
Apex predators are cool
I'm not convinced that Sarcosuchus couldn't death roll. I remember seeing a video of a rhinoceros running full tilt before tripping so hard it flipped head over heel and did a full somersault. Something that biometric models say should have killed it, but it just immediately got back up and trotted off like nothing happened. Animals regularly exceed the limits that biometric models place on them.
So the crocodiles alive today evolved from terrestrial beasts like this? I know alligators have remained basically unchanged (but used to be beyond huge) since the Cretaceous but were there also Crocs as we know them, or did their eventual form take shape much more recently?
Crocodilians are the descendants of terrestrial species, but they are far removed from Barinasuchus. True crocodilians (those descended from the last common ancestors of the living species) are only known from the Late Cretaceous onward, but their aquatic, crocodile-like ancestors date to the Jurassic Period. Barinasuchus is descended from a more basal branch that split off before the crocodile-branch of Crocodylomorpha became aquatic. Their last common ancestor was a small carnivore, but further back in the family tree were other large carnivores like Carnufex and Prestosuchus.
thanks, very informative. I'm just now trying to understand paleontology, consulting and trying to learn my Eon-Period chart for the first time. I'm prefacing with that because I'm still not quite clear. I'm sure that's a great answer but I didn't mean originally or crocodilians as a whole, I was just wondering if MODERN crocodiles are newer (as opposed to the alligator form which is extremely ancient, seen with deinosuchus) All living crocs came from long-legged freaks like Barinasuchus? I assume they couldn't compete with the mammalian predators on land so they abandoned it completely.
@@chimerasuchusSo crocodiles are a crocodilian that's had a "busier" evolution than alligators/caimans? Basically answers my question if so.. this form came about more recently in comparison, a totally different, more terrestrial branch became the aquatic man-eaters we know and love?
Crocodiles also date to the Late Cretaceous, although their fossils are less common than those of alligatoroids (the branch alligators and caimans belong to). Their common ancestor was also semi-aquatic, although some extinct branches (like the planocraniids) returned to a terrestrial existence, in addition to sebecids like Barinasuchus, whose ancestors were never aquatic in the first place. They actually did very well competing against mammals, with each lineage only dying out during times of global or regional extinction events. Unlike mammals, most land crocs were large or medium sized predators, so there were fewer small predators to replace them when this happened.
0:52 - Did you mean to say, “twice as long, as wide?” because you said it the other way around. Which is just, no.
I love how many autists there are out there to make cool videos like this, but you guys should really all use a different voiceover so it’s easier to listen to and your knowledge gets to more people
Honestly my favorite species of crocodile like animals of all time but I will say I love the depiction from primeval the best because that thing is massive it is terrifying and it's everything I would want if I had a Pokemon made from scratch based on a prehistoric animal especially that 6 m long description because being just about 20 ft long I could ride that thing into battle like a horse but so much cooler
The cross-species morphology comparisons are really well-fleshed out and logically sequenced. I personally feel vindicated as a obligate omnivorous biped! (Though descended from the synapsid lineage.)
Jurassic World didn't "imply" that the dinos featured were contemporaries.. 🤔 The JP series isn't some paleo-doc lmao It takes place in modern times to which dinosaurs from all throughout the Mesozoic were brought back‼️👏🤣
The prologue took place during the Late Cretaceous, not the modern day.
Lmao how is lotosaurus named if it hasn't been described yet? 🤔
I remember reading a LOT of super croc material as a kid, putting it up there as a super famous giant prehistoric cousin of our modern day creatures, ala megalodon. However, ever since my elementary school library, I never heard about super croc since. Maybe i made it sound much more important in my head 🫢
What is the genetically closest modern animal of Pterosaur?
@@shockdrake Funnily enough, birds.
Oh man, I understand how Simosuchus couldn't survive the extinction since they are land species of Crocs related but Iharkutosuchus !? Sad that they also couldn't managed to survived through the water like how the other crocs managed to, when Iharkutosuchus were also an aquatic type :((
Many people dream on petting a fascinating & harmless reptiles. Not only Simosuchus but Iharkutosuchus as well which is another herbivore crocs like Simo but more aquatic like Platypus. They would be more popular than the like of Iguana & even Platypus. They would have been the huge deal in pet trades
dinosaurs are Shuvosaur look-Alikes
maaaan they sure look strange many of those prehistoric things 😂😂. to me its no less than amazing that we even get to know that much about them from so fare back in time. while thinking.... i wonder how humans would look like in 200 to 250 MILLIONS years. super great clip tho.
So many errors in his video smh.
I'm more of a Deinosuchus or Sarcosuchus
Down. To the facts great job man !!!
Still waiting for the Jurassic and Cretaceous 🥲
Imagine living 35 years to reach adulthood, mustve been a struggle
I love the V/O!!
Loving the diagrams showing which bones we have found and how we extrapolate out to reconstruct the whole. Very helpful.
Has it really been six months since your last upload? This is concerning. I've learned more from you than any other paleo-related channel. I rewatch this material endlessly and still pick up new information. I hope you come back soon.
I am making more, it is just taking a while.
These guys are so awesome on Ark, you’re doing something and then boom, you’re in its mouth and getting chewed 😍😍😍 aside from that Kaprosuchus is a both awesome and an extremely terrifying thing, if it did actually run around like it’s portrayed, then I am extremely glad that it is extinct, this thing would definitely terrorise modern Africa if it were still alive.
A clear, succinct summary of what this channel is mainly about, and what attracted me to it. I'm glad I found this channel, and it inspired me to revisit an old idea I had of doing something similar for prehistoric arthropods (the planet's real "dominant" animal group).
Crocodiles is my favourite and likeable reptilian apex predator wild animal in the world that i don't want to mess with it,because I'm a fan wildlife animal lover but just totally afraid of wildlife terrify mother nature and that's why I'm interested about wildlife animal because of the variety with the difference characteristic behaviour.Crocodile been existed from many years since the era of the dinosaur in cretacious period and triassic period and jurassic periods,some people said that the crocodile is a dinosaur species and many of them said is not because the crocodile not a related dinosaur species.They were just prehistoric crocodile ancestor species,yeah sort like that I've been researching in the encyclopedia book or Google website internet online.
Its so mind-blowing that those tiny little reptiles that were probably a lot like shrews, weasels or foxes amongst all thess gargantuan animals evolved into the staggeringly ancient and successful crocodilians we still see today. Nature is wild
Honestly giant crocidile the size of a bus is more terrifying than a t rex. You know that thing ran fast asf too.
