About Koleken
What it was like
Koleken was an abelisaur, a two-legged hunter with a short head and tiny arms. It was a close relative of Carnotaurus, but its skull had no horns.
Its skeleton is fairly complete and comes from a young animal. It helps show that several kinds of abelisaurs lived together at the end of the age of dinosaurs.
Its world
It lived about 72 to 66 million years ago, at the very end of the Late Cretaceous, in what is now Argentina. Its bones come from the La Colonia Formation, where it lived alongside Carnotaurus.
How it was found
Pol and colleagues named Koleken inakayali in 2024, from a single find.
