Unlike modern sea turtles, Placochelys still had visible toes on its paddle-shaped limbs, and it had a short tail.1
Placochelys lived about 221 to 205 million years ago, during the Late Triassic Period.1
It had only two pairs of teeth on the roof of its mouth: a large pair at the back and a small pair near the front.1
