Koleken was a meat-eating dinosaur that lived in Patagonia near the end of the Age of Dinosaurs. It was a cousin of the famous Carnotaurus and had a unique skull that set it apart from other abelisaurids.1

izinto ezimnandi

Iinyani ezimnandi

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

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

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

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

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

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

Kwiingcali zeedayinaso

Igama lenzululwazi: Koleken
Inikwe igama ngu:: Pol et al. 20245
Iqela: Iidayinaso ezitya inyama
Usapho / iclade: Abelisauridae5
Ukuhlelwa: Theropoda > Ceratosauria > Abelisauridae5
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)5
Izakhiwo zamatye: La Colonia5
Amazwe: i-Argentina5
Iirekhodi zeefosili: 1 kwi-Paleobiology Database5
Ukufunyanwa: Koleken was discovered in the La Colonia Formation of Patagonia, Argentina, and was scientifically named by Pol and colleagues in 2024.1
Kusaxoxwa ngayo: Scientists are still debating exactly how Koleken is related to other abelisaurids and how fast its group evolved.1
