Thalattosuchians: The Marine Crocodilians

[@jaredmn8580]

One of the most underrated prehistoric animals.

[@EinarEle]

This channel should do a complete timeline of marine reptiles and comparison of body-shape and adaptations. That is, Ichthyosaurs, plesiosaurs, varinids and the various croc-forms. Possibly with a guess at future occupiers of the niche.

[@Alberad08]

Informative, detailed and also entertaining overlook on the topic - really enjoyed watching this! Thanks a lot!

[@chimerasuchus]

This was a great video about such an overlooked group of marine reptiles! There was one minor mistake. The art shown at 0:48 depicts the Triassic phytosaur Mystriosuchus, not a thalattosuchian. I guess it got mixed up with the ecologically similar Mystriosaurus?

Keep doing these videos man, you’re a gem

[@dudotolivier6363]

Will you made anothers videos about Proboscidean again, in a coming future ? Because we have one about the Mastodont, one on the the Amebelodontid, one of the Stegodontid (featuring also the Anacidae, called theTetralophodont gomphoteres archaic group) and one about the Mammoth. But there still others interesting groups of Proboscidean to explore, like the Gomphoteres, the different Elephantid groups and lineage like Palaeoloxodon, Primelephas and the Stegotetrabelodontinae with Stegotetrabelodon. The Early Proboscidean deserved also a good treatement, like the Moeritherium, the Numidotheriidae, the Barytheriidae, and the Deinotheriidae with the famous Deinotherium. It would be very awesome to have that again because that were really good videos !

[@dr.polaris6423]

Yes I’ll very be returning to Proboscideans in the future.

[@altanativeftw2625]

@@dr.polaris6423 You might already have these in what I imagine is a long queue for you, but the dasyurids (quolls), thylacinids (thylacines), phascolarctids (koalas), and macropods (kangaroos) would be interesting to see covered in your comprehensive clade overview videos. And I second Dudot Olivier's suggestion of covering basal proboscideans too.

[@dudotolivier6363]

@@dr.polaris6423 Amazing new ! 😁 Of course, it's would have been somewhat preferable to made the Proboscidean sub-series like the one of the Crocs, from the very early, basal/archaic to the extants, modern families of the groups, because it will be a little confuse for some, but overall that is just a minor nitpick. For some who aren't familiar with these animals, Proboscidean are mostly split into two major groups : - the Early Proboscidean, wich include the Moeritherium, his relatives, the , the, and the Deinotheriidae. -and the Elephantoidea, which include all the true elephants. Elephantoidae also is separated in two categories : -The archaic elephants, with the Mastodonts, the Gomphotheres, the Amebelodontid and the Stegodontid. -and the Modern Elephants with the Elephantid family, the only family of the order Proboscidea to survived to this day. It's the common and best view about how to see this order of animals. Maybe overall, in the big lines and short, but at least enough understandable for everyone. I hope we will not to wait too long for the return of this sub-series !

Pseudosuchians

[@obiwahndagobah9543]

He ment Pseudosuchians. It is fascinating how English speakers just omitt Konsonants in speaking, just because they are directly behind each other. Like Pteranodon and Psychology. I'm not aware of any other major European language doing that.

[@grahamstrouse1165]

@@obiwahndagobah9543Not really accurate. The OP wasn’t familiar with this particular lineage is all. It’s a fairly unusual consonant combination.

[@obiwahndagobah9543]

@@grahamstrouse1165 I'm sorry if I was not precise. I ment Dr. Polaris representing English (native) speakers in general, not the OP. I'm sorry if the OP did in fact misunderstand it. It was the exact thing I wanted to mention, that by omitting certain letters, people unfamiliar with these terms don't know how it is supposed to be written or what it could mean.

[@rafexrafexowski4754]

​@@obiwahndagobah9543 Actually this happened in most languages in Europe, it's just that English is the only one that still writes the unpronounced consonants.

[@Gayacegunslinger]

Very interesting video! I was aware of some more aquatic-adapted crocodilians, but I never knew they adapted so strongly to the ocean-going life as the Metriorhynchoids did! This is off-topic, but what do you think of the possibility of ammonites surviving into the very early Paleogene? From what I've seen, if they did make it past the K-PG mass extinction, they would've died out completely within 500,000 years.

[@tozarkt9805]

Please do a video about extinct and little-known members of the genus Panthera. I just heard about the European jaguar today.

Brilliant video, Dr. Polaris! I love the marine crocodilians in general, and I especially love Lemmysuchus! So glad that Lemmy had a glorious monster named after him! I can think of few greater honors that might be bestowed upon a person than to have a paleo-crocodilian named after oneself! --N

To think if some marine gharials tat loved recently had been managed to hold on and specialise on relative cetacean free waters they might have evolved to become neo metriorhynchids even alongside dyrosaurids like two genera converging and living alongside looking very similar to one another

No doubt ancestral to crocodiles, perhaps before sea creatures eventually came up onto land and evolved legs.

No, they are not ancestral.

Geosaurus was probably one of the worst named extinct animals. It was a marine reptile but it's name means earth reptile.

[@brianedwards7142]

You said archosaurs moved out of ocean niches. Are turtles no longer considered archosaurs? I'm getting old and sometimes don't know what's old science and what's current.

[@jgrandson5651]

The wiki says that recent genome studies point at testudines being the sister group of archosauria. That would make them archosauriomorpha, but not archosaurs

[@Dr.IanPlect]

In any case 'moved out of ocean niches' doesn't necessarily mean entirely.

[@robertjackson1813]

I'm not on board with thinking any of these crocodiles could give live birth. Just because these crocodylomorphs were Oceanic doesn't mean that they have to be life-bearing . Today gharials have to rely on sandbars to lay their nest; they are very much more aquatic than other crocodilians today it is a very risky nesting strategy and that would explain how there are no ocean-going crocodilians today and gharials are in such bad shape.

[@mattimorottaja8445]
