Ardetosaurus

What it was like

Ardetosaurus was a long-necked, whip-tailed sauropod from the same family as Diplodocus. It is known from a partial skeleton with bones of the neck, back, tail, hips and one leg.

Its world

It lived in the Late Jurassic in what is now Wyoming. Its bones come from the Morrison Formation, where it lived alongside Diplodocus, Allosaurus and Stegosaurus.

How it was found

Van der Linden and colleagues named it in 2024. The type species is Ardetosaurus viator. The skeleton was dug up decades earlier and spent years in private hands.
