Anchitherium clarencei
Taxonomy
Anchitherium clarencei was named by Simpson (1932). Its type specimen is FSGS V5074, a mandible, and it is a 3D body fossil. Its type locality is Midway, which is in a Hemingfordian terrestrial horizon in the Torreya Formation of Florida.
It was synonymized subjectively with Anchitherium navasotae by Forsten (1975); it was recombined as Kalobatippus clarencei by MacFadden (1998).
