Taxonomic list

• clearly overlies the Shoreline localities

•Leite cites 858 small and 59 large mammal specimens, but then lists 109 identifiable large mammals (not counting the peccary and gomphothere); apparent total is 967

•Voorhies' small mammal list is apparently more up to date than Leite's

•"Anouroneomys minimus" is actually from Black Butte: see Bown 1980; also omitted by Voorhies 1990

•"cf. Osteoborus sp." is omitted by Wang et al. 1999
