Doswellia: The Enigmatic Reptile From Late Triassic North America

[@posticusmaximus1739]

"The fauna of the Triassic was much more varied" that's an understatement lol.

[@kban77]

I thought there are more kinds of species in cenozoic than triassic? Maybe he meant different. Not varied?

[@georget4141]

@@kban77*more varied than the jurassic and cretaceous

[@tobiaschaparro2372]

Idk, you have to consider the passage of time. Some 150 million years later in the late cretaceous Dinosauria is made up of groups perhaps more distantly related than archosaurs in the Triassic.

[@bruh949]

The fact even giant arthropods still existed at this time such as Theiatitan a near 1 metre long and half metre wingspan killer Grasshopper that acted like a Praying Mantis (the last of the mighty family the Titanoptera). So cool to see how Arthropods continued after their peak on land and air and sea in the Carboniferous, to dominating in the air till the arrival of Pterosaurs where they would surrender the skies, like one day Pterosaurs would to birds.

[@owli-wankenobi3727]

So, it's almost an otter croc. That's awesome! There always seems to be another strange non-dinosaur archosauromorph that I didn't know about... this is why the Triassic is my favorite period of the Mesozoic. lol

[@Alberad08]

Thanks a lot for introducing me to Doswellia! What a great and informative as well as entertaining documentation - really liked it.

[@posticusmaximus1739]

Yass!!! I've been waiting for this obscure obscure archosauromorph!

[@beneficent2557]

The Triassic was my favorite period

[@Stegosaurus.Stenops]

I've been waiting for the day CHimera posted.

[@MegaRumia217]

It looks like a fusion of monitor lizard and a gharial.

[@nyeti7759]

I was going to say, some of those reconstructions make it look very water-monitor-like.

[@michaeldougherty6036]

Makes me think of Joanna from Rescuers Down Under.

[@anthonyhiggins6342]

Love this video. Keep focusing on these little known/lesser known animals, please.

[@bibia666]

CHimerasuchus 👍 🙏Thanks for the uploads! Very interesting as usual 😃 Greetings bibia 👋

[@thedimple773]

Oooh another one so soon. Blessed!

[@caseypalmateer4515]

You produce some of the best videos on you tube. Thank you for your work man.

[@vibuma]

Great video,love hearing about obscure extinct animals,specially when we have an almost complete fossil to get info from.

[@bruh949]

The Triassic was truly crazy… The fact even giant arthropods still existed at this time such as Theiatitan a near 1 metre long and half metre wingspan killer Grasshopper that acted like a Praying Mantis (the last of the mighty family the Titanoptera). So cool to see how Arthropods continued after their peak on land and air and sea in the Carboniferous, to dominating in the air till the arrival of Pterosaurs where they would surrender the skies, like one day Pterosaurs would to birds.

[@AncientWildTV]

thats fascinating fr. But I wonder what led to the decline of giant arthropods in the face of evolving predators like Pterosaurs and later birds?

[@Darth-Nihilus1]

I was looking at the sedimentary rock map of Pennsylvania and I live in Pennsylvanian aged sedimentary rocks from the Glenshaw and Casselman formation with Monogehala on top of the hills. Appalachian basin is awesome for fossil hunting because we have everything from Precambrian to Jurassic

[@Gfan2015-o5g]

Hey mate. Love your channel. I know you mainly do videos on pseudosuchians and Triassic reptiles, but would it be possible for you to do a video on Dryptosaurus? It's a super underrated dinosaur related to Tyrannosaurus that has a very interesting history within paleontology. For some reason, I feel like it would not be out of place in your catalogue since you mainly discuss obscure taxa.

[@rileyernst9086]

Another cool video about another cool archosauroforme!

[@alekrex5905]

I think Doswellia should be an animal that swam in search of aquatic invertebrates, for example, bivalves, molluscs and even insects that buried themselves at the bottom of a river, for example.

[@beneficent2557]

Archosaurian Metabolism is something I wish we had a better understanding of in recreating behaviors.

[@gaufrid1956]

It does seem to be very much like a monitor lizard, and of course there are water monitors. The armour is interesting. I guess if you are semi aquatic in the Triassic you need some protection, because a lot of very dangerous predators were in and around the water.

[@ecurewitz]

Thank you very much

[@joeshmoe8345]

Great, loved it

[@alexandermorrison1010]

By overall body shape this animal reminds me of Prolacerta. A very monitor lizard shaped beast. Low slung and rather elongate.

[@HassanMohamed-rm1cb]

I’ve got some great ideas and some great suggestions for you to make KZbin Videos Shows about some more Prehistoric Extinct Crocodilian Species, such as Lazarussuchus, Plesiosuchus, and Metriorynchus adding that to the episodes on the next Saturday on the next Chimerasuchus coming up next!!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️

[@rileymanders2167]

so good

[@mlggodzilla1567]

Another great video 😎

[@katboi7140]

This thing look like it'd make a good pet I want one

[@dannybrown5744]

😅😅

[@posticusmaximus1739]

Now that we've had an obscure Triassic proterosuchid, I'd like to nominate the opposite side of that spectrum: Archosaurus Rossicus, the Permian proterosuchid and oldest known Archosauriform. It's name gave rise to Archosauria although it's no longer considered a true Archosaur. Last year a ground breaking study concluded it was a high derived form, thus meaning Archosauriforms evolved millions of years earlier. This implies Archosauromorphs evolved even earlier, possibly during the Guadalupian epoch. The seeds of the age of Reptiles were planted in the Permian.

[@AncientWildTV]

Given the implications of this study, how do you think the environmental conditions of the Permian might have influenced the early evolution of these reptiles?

[@posticusmaximus1739]

@AncientWildTV I think it pushed them toward being endothermic. Being during the Karoo ice age plus the flucuating climates caused these animals to gradually increase their metabolism

[@AncientWildTV]

@@posticusmaximus1739 I also think their physiology, like improved respiratory efficiency or changes in insulation, enabling them to retain heat more effectively.

[@robertomontini5479]

do you make a video on the whole history of anapsids from Carbonfoero to today? Please please 🐢

[@posticusmaximus1739]

I'd like to know more about the parareptiles, including the holdovers that survives the great dying into the Triassic

[@beneficent2557]

Orbital Fenestrae for the win

[@1998topornik]

This creature seems like analog to water monitor lizards.

[@android65mar]

Looks like a platypus tail!

[@maozilla9149]

nice

[@HannahHäbler]

Sadly I have a hard time listening to the sound of your voice I love the information in your videos and work you put in them I mostly listen by KZbin premium while doing different things or before I go to sleep with closed eyes. (Sorry for mistakes I’m foreign)

[@georget4141]

visually it seems almost more like a nile monitor than a crocodilian

[@HardCoreSciFi]

Feeding on crustaceans sounds like the most plausible hypothesis. I wonder, maybe crustaceans (and/or crustacean analogues) were somewhat different during Triassic, which required narrower snout to hunt them.

[@One_Lepage]

Интересно, интересно...

[@nathancomixproductions466]

When you said "the Newark supergroup", I thought "When Dinosaurs Roamed America".

[@mistersir3020]

The Triassic was radical

[@aldogallegos-k6d]

A1 👍👍👍

[@ashb8036]

Maybe the built things in the mud like beavers with the flat tail

[@미제드론]

Is this a first pseudosuchia??

[@chimerasuchus]

No, it is just outside of Archosauria.

[@beneficent2557]

Crocodiliform Mustelid?

[@Zach-ku6eu]

Sound recorded in an old soup can?? 🙉
