With its lizard-like appearance and that distinctive sail on it back, Dimetrodon is practically the mascot of the Palaeozoic Era, a time before flowers, birds, mammals, and even crocodiles. But if you take a close look at this sail-backed animal, you might see a little bit of yourself.
Thanks to Franz Anthony and Studio 252mya for the Dimetrodon illustration. You can find more of Franz's work here: 252mya.com/gallery/franz-anthony

    Yes, but it's also clear that modern birds and dinosaurs are more closely related to each other than Dimetrodon is to modern day mammals, so much so that modern day birds are currently classified as dinosaurs, just as a lower classification of the overall group. This is especially clear when you see that prehistoric birds already existed at the time when other classifications of dinosaurs were still running around, and I'm not just talking about animals had dinosaurian teeth but also had feathers, by as early as the Jurassic you had bird species capable of flight and that showed distinctive features like beaks. You also had birds evolving to fit specific niches that made them more distinct than just arboreal feathered dinosaurs that learned how to glide or had the ability of powered flight. You had birds that lived in the forests, the coasts, and even sea birds that could not fly but swam through the water like horrifying monster penguins (hesperornis if you are wondering, a 6 foot tall sea bird with teeth that swam in the cretaceous oceans).

    There's also the theory that about half of Dimetrodon's "sail" was actually covered by a sort of hump - similar to a rhino's heavy back that is also supported by sail-like elongations on its vertebrae. This would provide more space for powerful muscles to run down its prey.

    Large hump of muscle, grizzly bears also have the same things and they are large predators. Though grizzly bears eat mostly plants, maybe dimetrodon was also happy to eat vegetable matter every no and then. It's not too unlikely, wolves eat berries and leopards will eat grapes and melons

  • @agilemind6241

    But how did they deal with the torsional forces that the sail (membrane or no) could cause on the spine? Twisting a single vertebra can't be good. Most muscle-based vertebra extensions are focused close to the shoulders (for quadupeds) not the centre of the back - as I believe dimetrodon's was, though maybe this could be explained by it's not-quite mammal & not-quite lizard gait.

    Ooh, I love the freaky Permian creatures. Mainly BECAUSE they were so weird--when you look at them, your brain tries to tell you (for example) "lizard" and "dog" at the same time, and eventually leaks out your ears. We humans don't do so well with almosts and in-betweens, we like to just (snaps fingers) put things we look at in a definitive little box. And it's so cool to think that these weird things were actually our direct ancestors. I'm also fascinated with creatures of this period because (a) you hear far less about them than other prehistoric creatures (so...what, I'm a paleobiology hipster? "Dinosaurs? Cenozoic mammals? Pff, I'm into synapsids these days. You've probably never heard of them.") but seriously, the fact that we DON'T hear about them so much makes them more interesting and (b) ...the fact that their story had such a tragic end. The Permian-Triassic extinction took away WAY more diversity than any of the other major disasters on Earth, and it was probably caused by something from within the planet itself, rather than a meteor from space...which makes it even scarier. Brrr. And I think we're all kind of suckers for a good Impending Doom story. And if you think about it, these guys are kind of _our_ "dinosaurs". Like, just as the bird-like reptiles (dinosaurs) aren't around anymore but their true bird descendants are, the "mammal-like reptiles" are completely gone but we have true mammals. Like that. Both in-between versions are now all dead (unless you count large scary flightless birds or platypuses), but were fascinating while they were here.

    Let's keep it simple. The Dimetrodon sail was..... a sail. 1. The sail would be used to help it cross wide rivers. Catching the wind and tacking its way across. 2. Female Dimetrodons would select her mate from the winners of sailing races that would take place every Thursday in local lake, with the females lounging on the beach, giggling and talking about the size of the male's sails. Yes, the Dimetrodon was definitely ahead of its time.

    I always enjoy a good bask in the morning sun, maybe it's a distant primal memory of the quick solar sail fin warm up - followed by running about biting meaty chonks out of all the other animals who were not early risers. Maybe that why why we still say stuff like "Don't skip breakfast, it's the most important meal of the day . . . " : )

    Infernoraptor Evidence is accumulating that a species of placoderm was actually the ancestor of all jawed fish that live today (and consequently of all tetrapods). So technically placoderms aren't extinct, because we are their descendants.

    That's the first i'd heard of that hypothesis. Interesting, but that's not to say an episode about them wouldn't be interesting. Plus, what you are saying is somewhat odd. If placoderms, which definitely had true bones, are the ancestors of all gnathostomes, does that mean chondrichthyans evolved from bony fish or did jaws evolve twice?

Is there a list of species from which we know humans directly descend, irrespective of how far in the past? I didn't have much luck simply googling this. Thanks!

    In short, yes, long windedly, yes but it's a very fragmented pathway. Because the fossil record can actually Never be 100% complete there's direct lineages we can never trace because the fossils just aren't there and going back further and further direct lineages are harder to define, more so we know that because we have these traits and these hyper ancient fossils also show it, these fossils are a distant ancestor of all mammals. Like we don't know what the first actual hominid is we only know what the earliest fossil hominid we've found is and I think I've seen videos that say that the earliest know hominids aren't even direct ancestors to us just cousins.
