I’m thinking larger looking lizards look more aggressive so I think the sail is to make them look larger just like a frilled neck lizard expand to scare away predators especially if attacked from above

You should do a video on albanerpetontidae at some point. They're easily some of the coolest lisamphibians, and they only went extinct pretty recently. Yaksha Perettii is a cool one with quite a bit of research done on it, might be a nice place to start 😉

I have been fossil hunting all around western Pennsylvania and eastern Ohio. I have donated a set of tracks from Batrachichnus. Also the Carnegie museum has it documented that Edaphosaurus was found in the Pittsburgh Red bed from the end of the Glenshaw formation in Turtle Creek Pennsylvania my home town. I find mainly plants from the Monongahela formation on the top of the hills to the Pittsburgh Red bed of the Glenshaw formation. I have found everything from bivalves, crinoids, horsetails, ferns, Lepidodendrons, and a ton of other stuff around the area. 😅 if you want to donate something to the museum you’ll need legal documents from the land owner and then the fossil will have to be as approved by the museum. It can take months

I'd like to think the sails eventually became an easily exploitable weakness over time, which may explain why there are no terrestrial animals that have sails.. The only known extant animals with such a feature are, of course, the sailfish family & Man-o'-War jellyfish family.. Edit: do correct me if I'm wrong about which existing animal groups have sails on their backs

Are these linked to Stegosaurus ? Maybe the sails morphed into bone plates ?
@jameshall130011 ай бұрын
They aren't closely related. Synapsids are a separate group of animals.
@chimerasuchus11 ай бұрын
Stegosaurs were dinosaurs, not synapsids. Their plates evolved from osteoderms rather than neural spines. That said, stegasaur plates and edaphosaurid sails have been proposed to have had similar functions.

guys quick question i remember seeing the answer here in the comments but i forgot wat video it was. so basically wat animal group ruled? before the dinosaurs i know there was a big extinction that allowed them to flourish. and who took up the niche of the dinosaur shortly after. i know it wasnt mammals yet it came later.
@chimerasuchus10 ай бұрын
During the Permian Period (roughly 300-250 million years ago) the dominant large land animals were synapsids, the distant relatives of mammals. Most were rendered extinct during the mass extinction at the end of the Permian, and they were replaced by the archosauromorphs, the group of reptiles dinosaurs and crocodilians belong to, early during the Triassic Period. While archosauromorphs were "dominant", there were still a few large synapsids, and the crocodilian branch of Archosauromorph, Pseudosuchia, was actually more abundant and diverse than the dinosaurs. That only changed due to another mass extinction at the end of the Triassic, which left the dinosaurs as the only remaining large to medium sized terrestrial animals. So the rise of the dinosaurs was actually the result of two mass extinctions. After the non-avian dinosaurs perished, there wasn't really a dominant group of animals. Some birds and ectothermic reptiles grew bigger, but large animals weren't common until mammals finally took up the mantle.

@WaddyMuters11 ай бұрын
Kind of irresponsible to not give the most well established reason for the back sail. In fact most experts today believe that the sail was used as an escape mechanism. Two Ianthasaurs embracing could form a perfect pair of wings to take flight an escape danger. That’s also also who pairbonding in mammals evolved. Dimetridon obviously evolved the sailback through evolutionary pressure to give case.

Nice video as always. I must add that calling it a Pelycosaur or a "Mammal Like Reptile" is now an outdated practice. Primitive Synapsids or STEM Mammal would be more accurate. That said, If you can, can you please do a Rutiodon video please? Love your content as always
@chimerasuchus11 ай бұрын
After having made videos about the topic for so long, I have found that using paraphyletic grades as common words (as "fish" is used) can be quiet helpful when trying to communicate these topics. In this case, the term "pelycosaur" was used to not just distinguish these early synapsids from mammals but from the rest of the therapsids which dominated the later half of the Permian Period.
