Did I mention I teach figure drawing? Would I loose followers or offend anyone if I posted figure drawings here? Or should I just stick with dinos? We’ll see, I guess.

Mid afternoon: the sun hangs low in the sky, its light bleeding through the canopy of an Early Permian (272 MYA) forest. Amidst the trunks of primitive conifers, a small group of Edaphosaurs snuffle slowly through a underbrush of ferns, using small peg-like teeth they snip off an ample bounty fronds, absently grinding them using the broad, rough plates affixed to the backs of their bizarre but powerful jaws. Amongst the foliage the patterning on their large sails help to break up their outline, providing a modicum of protection from would-be predators; sadly that protection isn't enough and they are oblivious as another sail back cuts through the ferns behind them. Their cousin, Dimetrodon limbatus has come round for what can only be a very unpleasant family reunion. E. pogonias was an extinct synapsid, like it's relative Dimetrodon it possessed a large sail on its back, but unlike its cousin it was a herbivore. At 11.5 ft and 660 lbs Edaphosaurus was one of the bigger animals in it's environment.

This fossil is that of the Dimetrodon, which lived about 270-300 million years ago during the Permian period :) You may have seen them in those smol toy dinosaur sets, but fun fact: the most common misconception about this big boi (do yall think 11-ish feet is big??) is that it's a dinosaur. It's actually not; Dimetrodon died out millions of years before the first dinosaurs roamed the Earth. The interesting thing, though, is that the Dimetrodon is more closely related to mammals, like us, rather than any modern reptiles (they're not a direct ancestor of mammals tho). Thus, we can classify them as the fancy "non-mammalian synapsids" or simply "mammal-like reptiles".

The bigass spiny thing on the Dimetrodon’s back is called a “sail”, the role of which is debated but largely considered to have been used for thermoregulation AKA used to capture heat from the sun w that sPIcy amount of surface area ~ooOh~. Other less popular ideas argue that its purpose was for stability of the spine, courtship display, or some form of intimidation.

small-custard assessment: I give the Dimetrodon a 7/10.

A good boi. Da bestest. (On the other hand, is this Dimetrodon, or Edaphosaurus?) #Paleontology #Science #SciComm #NotaDinosaur #Fossil #Fossils #Geology #Biology #Zoology https://www.instagram.com/p/CGwdMMbASg2/?igshid=18i2crzt0gzjo
