Dipodomys kansensis
Taxonomy
Dipodomys kansensis was named by Hibbard (1937) [also but incorrectly said to be 1939]. Its type specimen is KUMVP 3945, a mandible (lower left jaw, bearing incisor, p4, alveoli of m1, m2, and m3; angle, condyle and coronoid process missing), and it is a 3D body fossil. Its type locality is Edson, which is in a Hemphillian terrestrial horizon in Kansas.
It was recombined as Prodipodomys kansensis by Hibbard (1939), Jacobs (1977), Dalquest et al. (1992).
