Taxonomic list

• upper levels have yielded Mammuthus sp. and Equus cf. conversidens: Carranza 1992

•list based on Arellano and Azcon 1949, repeated by Miller and Carranza 1984

 Testudines - Kinosternoidea
Kinosternon sp.1 von Spix 1824 mud turtle
 Testudines - Pantestudinidae
Testudo sp.5 Linnaeus 1758 turtle
 Squamata - Colubridae
Lampropeltis intermedius1 Brattstrom 1955 colubrid snake
from CIT 505
 Rodentia - Sciuridae
Paenemarmota barbouri Hibbard and Schultz 1948 squirrel
seems OK because it is repeated by Miller and Carranza

"Equus simplicidens" = Equus (Dolichohippus) simplicidens2 Cope 1892 horse
"E. (Dolichohippus) sp." of Miller and Carranza 1984; probably also includes "Pliohippus cf. osborni," which was compared to Dinohippus mexicanus and Pliocene Equus; this is an old Stirton i.d. and I believe it is repeated incorrectly by Miller and Carranza 1984
