Taxonomic list comments:six fossiliferous levels, but no detectable faunal turnover: Pratt 1990 NISP 2445, based on Pratt 1990, but this excludes small mammals (NISP 82+) and includes 250 specimens that may be specifically indeterminate; total about 2527; Pratt and Morgan 1989 report 81 specimens of two species for which Black 1963a reported 5, hence his 105 specimens in three other species may now be represented by about 1700, for a rough total of 1783 small mammals and 4310 overall |
