Eocene Amynodonts from Southern California

Abstract

Introduction.-Since the description' of a skull of Amynodontopsis bodei and of a lower jaw referred to this species from the uppermost Eocene, further dental parts have become available for study from localities in the Sespe. These furnish additional characters of value in recognizing the species represented in western Eocene deposits. Now also available is a fragment of skull with cheek-teeth from the Poway Eocene of San Diego County, California. This specimen possesses special significance because it permits a comparison with related forms in America and China. It is likewise of interest because it differs from the amynodonts of the Sespe and is clearly an earlier type. Amynodon reedi, n. sp. Type Specimen.-No. 2529, C. I. T. Vert. Pale. Coll., a fragment of the left side of the skull with P4-M3 inclusive, plate 1. Locality.-Poway conglomerate and cross-bedded sandstones exposed at C. I. T. Vert. Pale.
