Anchitheriine Horses from the Merychippus Zone of the North Coalinga District, California

Abstract

Excavations by the California Institute of Technology in the Merychippus zone of the North Coalinga district, California, have added considerably to our knowledge of the Equidae from this horizon. In addition to a large amount of material representing the genus Merychippus, the teeth of three genera of anchitheriine horses have been found. These teeth are of value in that they furnish additional information regarding the taxonomic position and geographic distribution of several of the middle Tertiary genera known from the Pacific Coast and Great Basin provinces.
