Cedaromys ("Cedar mouse") is an extinct mammal which lived during the Upper Cretaceous, at the same time as many dinosaurs. It was a member of the also extinct order of Multituberculata. It's within the suborder of Cimolodonta, and a possible member of the Paracimexomys group.

Species

The species Cedaromys bestia was originally named Paracimexomys bestia in 1991,^[1] but later reassigned to Cedaromys by Eaton and Cifelli in 2001. Fossils have been found in Albian (late) - Cenomanian (early), (both Upper Cretaceous)-aged strata of the Cedar Mountain Formation in Utah (USA).

Fossils of the species Cedaromys parvus (Eaton & Cifelli, 2001) have been found in strata of the same age in the Cedar Mountain Formation. This species is also in the Oklahoma collection. Suggested bodyweight is around 90 g.
