1

Koleken is known from a partial skeleton that includes skull bones, many back and tail vertebrae, a complete pelvis, and almost complete hind limbs.1

2

It lived about 72 to 66 million years ago during the Maastrichtian stage of the Late Cretaceous.5

3

Koleken was a furileusaurian abelisaurid, a group of South American carnivorous dinosaurs that lived in the latest Cretaceous.1

4

Its name comes from the Teushen language and means 'coming from clay and water', because its fossils were found in claystone rocks from an ancient estuary.1

5

Koleken was named in 2024 by a team of paleontologists including Diego Pol and others.5

6

It lived alongside another abelisaurid, Carnotaurus, but Koleken had a different skull shape and other unique features.1
