Dimetrodon milleri

Sometimes people confuse Dimetrodons for dinosaurs, when actually Dimetrodons are in the class of Synapsida; a class more related to mammals than reptiles. Dimetrodons ranged from the Lower to Middle Permian; which also means they did not live alongside dinosaurs (another misconception).

Preach. The fact that they’re synapsids needs to be a bit more well known amongst dinosaur ‘enthusiasts’.

this looks like it was taken at the Harvard Museum of Natural History. :)
