Before the dinosaurs, Earth was home to strange, reptile-looking creatures called synapsids that roamed the land on four legs.

Though some look reminiscent of crocodiles and turtles, they’re actually the early ancestors of today’s mammals.

And a newly discovered synapsid species unearthed in France may have lived like a mammal we see today.
