About Niebla

What it was like

Niebla was an abelisaur, a two-legged hunter with a short, deep head and tiny arms. It is known from part of a skull, a shoulder blade and a few other bones.

Its world

It lived about 72 to 66 million years ago, at the end of the Late Cretaceous, in what is now Argentina. Its bones come from the Allen Formation, where it shared the land with the hunter Abelisaurus, the raptor Austroraptor and the titanosaurs Aeolosaurus and Neuquensaurus.

How it was found

Aranciaga Rolando and colleagues named Niebla in 2021, from a single find.
