Hey Dr.Polaris, why don't you think about making a suggestion and creating a RU-vid Videos that's all about the evolution of and the history of the Prehistoric Marine Reptiles called the Plesiosauria, (Plesiosaurs, Pliosaurs, And Polycotylus) in the next couple of weeks to think about that one coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
They say the first author is really, really, really hot Jokes aside, thanks for featuring our study, it is a fun experience going from watcher to video topic.
Glad you enjoyed the video! If at SVP hopefully we can chat, I'm hopefully starting grad work on some Triassic material in spring, applications don't open until August, but my likely advisor seemed excited about the idea.
I love how the understanding of dinosaur phylogeny is always evolving. I'm only in my twenties, and just in my lifetime, so much of the conception of dinosaurs has changed considerably, but they're still awesome.
I dont know if this will be ever proved but the more i see the phylogeny of dinosaurs going back so far into the Triassic i cannot stop having this feeling that maybe the whole superorder of Dinosauria is actually several branches of archosaurs that just happened to have very convergent features between each other and that's why they got grouped up after they got first discovered.
Literally impossible from a nomenclature standpoint and a taxonomic one. As it is currently stands dinosauria is defined as the last common ancestor between triceratops horridus, diplodocus Carnegie, and passer domesticus, and all its descendants to the exclusion of the pterosaurs. So unless you end with pterosaurs being related to one more branches of dinosaurs to the exclusion of others than dinosauria is a valid group. The various proto Dinosaur archosaur clades we see leading up to dinosaurs are all named after the 1950’s and hence do not have priority over dinosauria proper, so if anything happens that one or more these fall within the dinosaur clade tree they’ll just subsumed into dinosauria.
Does this seemingly mounting evidence in favor of Silesaurs being earliest Ornithischians also imply that the deepest split in Dinosauria is the conventional one with Saurischia after all? And not an alternative one like Ornithoscelida? I mean, even trees that have Ornithoscelida at least reconstruct Silesaurs as being completely outside so I guess that Ornithoscelida grouping falls apart if all the Ornithischians go in a clade with Silesaurs as well...
They are seemingly simply stem ornithischians, regardless of ornithoscelida or any of the other hypotheses. And there was a recent paper which suggested all understandings about the larger group splits are about equally likely statistically.
Why don’t you think of a suggestion making a RU-vid Videos all about Dakosaurus, the “Biter Lizard”, an Extinct Prehistoric Metriorhyncid (the Marine Crocodile) the “Godzilla” of the Jurassic and the Cretaceous Seas on the next Raptor Chatter coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
