The combination of characteristics including a large skull, prominent supraorbital ridge above the dorsal aspect of the orbit, anteroposteriorly compressed cervical vertebrae, and robust, proportionally short hindlimbs with a tibia shorter than femur ...
Koleken was found in outcrops of the La Colonia Formation, which dates to the Maastrichtian (Cretaceous)–Paleocene (Paleogene) boundary. [3] This formation is best known for fossils of the abelisaurid theropod Carnotaurus and the saltasauroid titanosaur Titanomachya, [1] [4] as well as fossils of other reptiles including the turtle Patagoniaemys, the snake Alamitophis and the plesiosaurs ...
