Parikimys carpenteri is a multituberculate which existed in Colorado at the end of the Cretaceous period. The species is named "in honor of the DMNS vertebrate paleontologist Ken Carpenter, whose initial field work in the sparse, non-marine Cretaceous exposures of Weld County inspired this project."While the species shares several morphological characteristics with Mesodma, there are a few characters that set it apart.
