Paleocene genera

Kosmodraco is a genus of large bodied choristodere from the Paleocene of North America. Originally described as a species of the closely related Simoedosaurus, it was found to represent a distinct genus in 2022. Multiple fossil skulls show a relatively short and robust snout and a skull that is considerably wider behind the eyes. Two species are currently recognized, K. dakotensis and K. magnicornis.
