Gilmoremys is an extinct genus of softshell turtle which lived during the late Cretaceous (Maastrichtian stage) of North Dakota, Montana and Wyoming, United States. It is known from five skulls, a mandible and an incomplete postcranial skeleton. The holotype USNM 6727 consists of a nearly complete carapace and an isolated hyoplastral fragment, was first assigned to the species Aspideretes lancensis. Many additional specimens were later discovered including cranial remains, and the material was assigned to its own genus, Gilmoremys. It was found from the Hell Creek Formation and from the Lance Formation (only the holotype). It was first named by Walter G. Joyce and Tyler R. Lyson in 2011 and the type species is Gilmoremys lancensis. The generic name honors Dr. Charles W. Gilmore.^[1]
