Mastodonsaurus

More than 2,000 of them are helping scientists uncover a huge skeleton.

It's what remains of a huge prehistoric amphibian called Mastodonsaurus.

Haha, remains.

Anyway, what's an amphibian? Is that like a giant

frog? Not exactly.

Mastodonsaurus looked more like a huge crocodile.

It had a wide flat head, a long mouth, and sharp teeth.
