About Actiosaurus

What it was like

Actiosaurus is known from a few limb bones. It was once thought to be an early dinosaur, but later studies suggest the bones belong to a marine reptile instead, so it may not be a dinosaur at all.

Its world

It lived at the end of the Triassic in what is now France.

How it was found

Sauvage named Actiosaurus in 1883. The type species is Actiosaurus gaudryi.
