Taxonomic list
• this is most or all of the "Grand View" fauna of Wilson 1933 and apparently was relocated by Hibbard; the main Jackass Butte site of Shotwell 1970 is on the SW side
specimen of "Plesippus idahoensis" of Schultz 1936 could be from this locality if it is the same as CIT 119; CIT 118, directly across the Snake River, also yields this form: Schultz 1936
Borophagus diversidens Wang et al. 1999: Jackass Butte, IMNH loc. 77006
large mammals are from 50' west and "within five feet stratigraphically" of small mammals
