Abstract

The Castolon local fauna has been restudied in the light of newly discovered specimens from the Delaho Formation. These help to affix a more precise, later Arikareean age for the assemblage. Six new taxa, including new species of Heloderma, Brachyerix, Gregorymys, Michenia, and a new genus of sciurid and floridatragulid, are described. The oreodont Phenacocoelus leptoscelos (Stevens) is shown to be the remote ancestor of Barstovian and Clarendonian Ustatochoems.
