Taxonomic list

• mistakenly said by Barbour to be in Brown Co.; see Skinner and Johnson p. 292
not the same as Tetrabelodon Skull Quarry
not clear if additional taxa were found at this locality or elsewhere on the Snake River: Aepycamelus sp. ("Alticamelus") (second camelid) Hipparionini indet. ("Parahippus," "Hipparion," and "Neohipparion") Teleoceras sp. ("Teleoceros fossiger" (sic)) Merycodus necatus - seems doubtful as necatus is a lower Valentine species
