A miacid from the Sespe Upper Eocene, California

Abstract

In addition to three distinct types of hyaenodonts now known from the Sespe Upper Eocene(1) (Locality 150 Calif. Inst. Tech. Vert. Pale.), there remains to be recorded another creodont, namely, a representative of the family Miacidae. At Locality 150 skull and jaw materials of this form occur nearly as abundantly as do those of the Hyaenodontide. Special interest attaches to this miacid in view of its relationship to Pleurocyon, a genus described by Peterson(2) from the Upper Uinta (Uinta C).
