Species
The species
Cedaromys bestia was originally named
Paracimexomys bestia in 1991,
[J. G. Eaton and M. E. Nelson. 1991. Multituberculate mammals from the Lower Cretaceous Cedar Mountain Formation, San Rafael Swell, Utah. Contributions to Geology, University of Wyoming 29(1):1-12] but later reassigned to
Cedaromys by Eaton and Cifelli in 2001. Fossils have been found in Albian (late) - Cenomanian (early), (both Upper Cretaceous)-aged
Stratum of the Cedar Mountain Formation in
Utah (United States).
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.
