Collection methods and comments
| Collection excludes: | some genera |
| Reason for describing collection: | general faunal/floral analysis |
| Taxonomic list comments: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 | |
