The Osteology and Relationships of the Pliocene ground squirrel, Citellus dotti Hibbard, from the Ogallala Formation of Beaver County, Oklahoma
MetadataShow full item record
Enough material of the Pliocene ground squirrel, Citellus dotti Hibbard, from Beaver County, Oklahoma, is known to give some idea of the dental variation in this species. The generalized dentition is at the otospermophilid grade of development. Skeletal characters do not indicate a close relationship to any of the recent subgenera of Citellus. The skull has a moderately short and very broad rostrum; limbs are of a specialized fossorial type. The species is placed in a new subgenus, Buiscitellus.
