The Khodzhakul Formation is a Cenomanian aged geologic formation in Uzbekistan. Dinosaur remains are among the fossils that have been recovered from the formation.[1] As well as those of Mammals.[2] It is part of the same stratigraphic succession as the overlying Bissekty Formation.

Fossil content

One of the largest mammals of the Mesozoic, Oxlestes, occurred in this formation, and may have predated on dinosaur species.[3]
