Poposaurus really fascinates me. It seems like in some ways the croc-line and bird-line archosaurs were converging on the same body plans during the late Triassic and maybe if things had gone down just slightly differently we could be living in a world where the animals we know as Dinosaurs had been pseudosuchian in ancestry as opposed to avemetatarsalian.
It does seem like the Triassic extinction is what gave dinos their opportunity. I've always wondered if that meant croc-line archosaurs had a competetive advantage over early dinos, or they just evolved first and thus filled niches first. Either way, they likely would never have reached big dinosaur proportions, as they lacked skeleton-lightening adaptations like pneumatized bones that helped dinosaurs get so massive. I wonder if that means dinosaurs would have eventually out-competed them anyway, but in an attritional process rather than capitalizing on the end-Triassic extinction.
@@denderrant I think people overestimate competitive exclusion personally. Many groups once thought to be outcompeted died out for other reasons (pterosaurs, multituberculates) and groups once thought to be permabanned from certain niches turned out to have had a way in (gobiconodontid mammals were large carnivores in the Mesozoic).
We’ve had crocodilian cats, crocodilian Tyrannosaurs, and now crocodilian raptors. I’m starting to think that the term “copy cat” really should be changed now
Poposaurus sure is just another reason why I love prehistory and the evolution of crocodiles and their relatives,also yeah this video was pretty good and I love it
This is so amazing, i would never have guessed that a pseudosuchian convergently evolved the dinosauresque posture. It really seems like "crocs" tried everything during the history of earth uh? amazing creatures, thanks for covering these topics pal! your channel never cease to amaze me on how much we overlook in natural history and evolution.
Its so great hearing about a type of animal that is frequently overlooked in the nat history youtube sphere, and heaps of thanks for the amazing art to bring it to life for us! Love both your work!
Yeah I never heard of this before. It's a shame the makers of walking with dinosaurs and walking with beasts never made another series expanding into other species and periods.
It's interesting how archosaurs keep trying to evolve theropod bauplans, something that has never happened in the synapsid line. There must be some fundamental anatomical reasons for this. Interesting to think about, probably significant to larger questions- such as how evolution is in many ways a one-way ratchet, and you cannot recapture the phenotypic plasticity inherent in a lineage before it becomes diverse and specialized. I wonder if this is reified at the molecular level as well in terms of genome architecture- increased specialization results in new arrangements of gene networks that cannot be disturbed or reversed
I wonder if Hominoids are the Theropods of the mammal line, think about it. Bipedal, check. Apex carnivors, check. Grasping claws, I'll check in after another million years but knife hands are kinda similar... so check?
@@carlosalbuquerque22 African pangolins I'll give you, they do have a roughly theropod-like balancing of the body over the hips with the tail when walking. Ground sloths were not fully bipedal. Sthenurine kangaroos perhaps yes. Yet this evolution happened many times in archosaurs, essentially never in mammaliformes except in very anatomically idiosyncratic lineages. Perhaps the reason is in archosaurs the pelvis/thigh muscles are evolved to attach in the tail, whereas this is not the case in mammaliformes. In this sense the sauropterygians would be the odd lineage out, with a very reduced tail that resulted in a very non-saurian oar-like swim movement rather than the typical saurian side-to-side movement.
thank you so much for all of your pseudosuchian and extinct crocodylomorph coverage! they're so fascinating and tragically underrepresented in paleo media.
Great video. The Pseudosuchians are a fascinating wellspring of evolutionary adaptation, and too often people who know nothing of them other than "lol, croc is big lizard" overlook their amazing evolutionary history.
Wow! Quite a unique and important beastie! As you mentioned, the "convergent evolution" traits of this animal are absolutely amazing and present some truly spectacular evidence that the croc line and the dino line did indeed have some eerily familiar Grandparents. Thanks again dear Folks!
I am really enjoying this channel. I like that it covers the more mysterious and lesser known prehistoric animals. This is an area of science that I am not particularly knowledgeable on and always grateful to learn more. Thanks and cheers.
Your videos are non stop bangers. Honestly I've never cared too much about natural history. Couldn't even tell you what order all those "Assics" go in. But you make them super interesting
Very interesting specimen. Indeed, this is the first I have learned of it. Considering the fact, that therapod dinosaurs (or the ancestors thereof) had not yet evolved into their niche, meant it was pretty much wide open to any creature that wanted it. So it would only stand to reason that some convergent evolution was practically ensured to happen. Overall, I love the video.
I really enjoy how new discoveries have sharpened out knowledge of these ancient creatures. This presentation's educational and entertaining artwork is enhanced by the narrator's easy to listen to voice. Keep up the great work. Looking forward to the next presentation. Cheers, Dick from Vancouver.
Really interesting, again an insight into a world just as exciting and varied as anything that came after it and set there scene for the rest of time, yet receives so little coverage. Only thing perhaps worth mentioning when talking about the feet and footsteps for be that it’s appears to be plantigrade?
Well I can see one clear mistake here, at the end of the video (after 8:10) that Poposaurus clearly should be outfitted with a top hat and a cane. Contact your excellent artists and I am sure they would be overcome with the need to include those accessories. Otherwise, excellent work as always.
With the way that pseudosuchian looks, and for my childhood's sake...surely it's destiny that in a couple years time there'll be a discovery it hunted in packs?! 😂 Great video as always!
Great video!! Poposaurus and it's kin intrigue me to no end and tbh, really ich that need for a more retro style dinosaur-like organism of the early days of paleontology that i sometimes miss when studying dinosaurs currently, so thanks poposaurus being being so unique and un-stereotypical, that you become stereotypical! Lol
Just wondering, but is the trend of depicting Rauisuchians with inward-pointing fingers accurate or is it theropod "baggage"? All modern crocs have their front legs pronated as their default posture, so shouldn't Rauisuchians share this characteristic?
I am not sure how Poposaurus's arms were arranged. Another bipedal pseudosuchian, Postosuchus, had semi-pronated hands. However, Postosuchus may have been quadrupedal when its was younger. It should also be remembered that all crocodilians are quadrupeds whose locomotion has changed greatly from their more Postosuchus-like ancestors, so the arrangement of their limbs is not necessarily representative of the earlier pseudosuchians.
Great video, but regarding Poposaurus' long tail, perhaps it was used as a balance? Going by the images I can find online, it looks to be relatively front-heavy in comparison with similar-sized theropod dinosaurs, especially given that I'm not sure if it had the skeletal pneumaticity that dinosaurs had. Basically, the increased length of the tail might just be because it needed a bigger counterweight to maintain the same body posture than theropods did. I'd be curious to see how a biomechanical study of it would go.
The designs of the velociraptors from jurassic park does really resemble this creature . However there is a dinosaur that actually resembles these designs from the movie , i think that dinosaur is called herrerasaurus from the triassic period , it's almost identical to the raptors in appearance but it did not have the large claw on the feet and also there was no evidence that herrerasaurus had feathers as it wasn't related to dromeosaurids and wasn't a theropod .
Poposaurus seems a conjuction ring trough crocs and birds. In facts they have experimted the bipedism before theropods. It's very interesting that Dogon people of Mali believes in creatures called Nommo (figures as bipedal crocodiles) coming from Potolo (so they named Sirius B a twin star of Sirius) that bring to humans the civilization. Obviously it's just a link but it's funny to note the similarity whith these crocodilomorpha
a lot of people said that the Triassic was a weird time but for me the most fascinating place in earth's history has got to be South America during the first half of the Cenozoic era.
Im just a casual viewer with no anatomical knowledge on animals, but the long tail you mention it has and what it could have been used. Could it have also been used to keep balance during sprinting, much like a cheetah? Poposaurus didn't stand particularly tall for a therapod (or therapod-like creature) of that size, so maybe it preyed on small animal like our mammal ancestors hence why it didnt seem to stand upright much. HIgh speed chasing while your face is really low down would require strong balance and directional changes, much like a cheetah? Just a thought.
My first thought is that the tail structure could be useful for swimming... I'd be interested to see if any of its other features back up a partially aquatic lifestyle a la baryonyx and spinosaurus.
Quick theory. Since Paposaurus was a Saurian-Like Crocodilian. What if Paposaurus was the early ancestor of Baryonx, Irraitor, Suchomimus and Spinosaurus? This was the only Pseudosychian that evolved into an Archasaur Saurian?
I wonder how it's lower leg histology would look like, if it could springstep on its legs to compensate on their shortened length I would imagine it could use the pronounced vertebrae (the so-called hump) as a direction change counterweight that is close enough to its main mass. I'd imagine that it would be preferable, in order to conserve energy, than to have a longer and thicker tail.
Really interesting animal. I'm a bit confused about the feet; many images show it being plantigrade, others showing more digitigrade style. Do we not know how it walked?
I wonder if at all possible there was a potentiality that poposaurus was the result of a hybrid between sarchosucid and dinosaur thus resulting in its high metabolism and similarities between it and dinosaurs
Great video!by the way can be resurrect poposaurus by altering DNA of cocodriles moderns is there a chance of that happening or am I wrong?i like cloning,it's just an example

ladies and gentlemen, seems we have finally found a replacement to the feathered raptors to be used in non JP media
Interesting video. The JP Velociraptor was actually a Deinonychus.
It’s possible that the tail might’ve been detachable and the specimens discovered might’ve had theirs regrown thus the odd shape.
Raptors the best dinosaurus
The reverse suchumimus
That tail is used as a whip. The base is so thick it could be needed for fast snaps of the tail.
So basically all those old movies with the scaly dinosaur had some truth after all.
Can you please do a video on Yutyrannus next?
My first thought is that the tail structure could be useful for swimming... I'd be interested to see if any of its other features back up a partially aquatic lifestyle a la baryonyx and spinosaurus.
The tail really wouldn't help too much for swimming though, it's far too skinny, even when compared to sea snakes or Eels.
Quick theory. Since Paposaurus was a Saurian-Like Crocodilian. What if Paposaurus was the early ancestor of Baryonx, Irraitor, Suchomimus and Spinosaurus?

it looks like it could live on the real Skull Island from Kong 2005, not that other one...
Is it known if the long tail would have been flexible enough to be a weapon, akin to the whip tails of sauropods?
Think the tail could have been used as a lure.?for small cynodonts fish or the early dinosaurs or even slightly prehincyle
i wish perihistoric croc and dinosaur still live by now, i actualy like them as pet..
Now is it digitigrade or plantigrade?
Because you see BOTH in this video and it's confusing....
Convergent evolution happens in every generation, whatever works in that time period will happen
