Taxonomic list

• elevation 3300' (Hibbard 1957b) or 3290' (Hibbard and Zakrzewski 1967 and later references)
stratigraphically above most of the other Hagerman localities and definitely low in a normal zone, with Gauss/Gilbert chron boundary at roughly 3190': Neville et al. 1979; this would be 3.55 Ma based on Cande and Kent 1992, which is concordant with KA dates
