ደስ ዝብሉ ሓቅታት

Placochelys had a flat, turtle-like shell made of knobbly plates, but it was not a turtle. It was a type of reptile called a placodont.1

Its skull was compact and triangular, with a beak and powerful jaw muscles for crushing food.1

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
