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: https://252mya.com/gallery/franz-anthony
