Taxonomic list

• according to Hulbert 1988c, "Hippotherium cf. occidentale" and Hipparion cf. tehonense are present but were not found in situ
material of "Cormohipparion emsliei" reported by Hulbert 1988b apparently is from a younger horizon elsewhere in the mine
lists used from 1993 - 2000 included the following unreferenced taxa: Teleoceras sp., Aelurodon sp., Barbourofelis sp., Camelidae indet., and a "gelocid"; these apparently are not discussed in any publication, and the list may have been given in a c. 1989 personal communication from Hulbert that was lost around 1990
