A mounted Dimetrodon skeleton. Photos taken in 2005 at the Staatliches Museum für Naturkunde in Karlsruhe, Germany.

Dimetrodon is often mistaken for a dinosaur, but it pre-dates the earliest known dinosaurs by about 40 million years — and it’s actually more closely related to mammals.

Although its large sail is often explained as a heat-regulating structure, recent studies suggest it might have had a role in sexual selection.

    Looks like it’s all or mostly cast/sculpted, FWIW

    Apparently the tail was assumed to be pretty short until a decent amount of caudal vertebrae were described in 1927, so...

    This is D. limbatus, the same species: The tail does look strangely short but part of it could be perspective.
