Taxonomic list

Mammalia
 Artiodactyla - Merycoidodontidae
"Desmatochoerus (Paradesmatochoerus) sanfordi" = Mesoreodon minor, "Hadroleptauchenia extrema" = Leptauchenia major, Desmatochoerus hatcheri
"Desmatochoerus (Paradesmatochoerus) sanfordi" = Mesoreodon minor Douglass 1903 oreodont
"Monroe Creek formation, 'upper part of the deposits,' 1 mi. W. of Quiver Hill, Washabaugh County"; because "H. extrema" also was referred to the "Monroe Creek" by these authors and both forms are placed in the Sharps B by Tedford et al. 1985, this must reflect a change in stratigraphic nomenclature
"Hadroleptauchenia extrema" = Leptauchenia major Leidy 1856 oreodont
"1 mile west of Quiver Hill, top of second white zone, 168 feet above first white zone"
Desmatochoerus hatcheri Douglass 1907 oreodont
from "Quiver Hill area, Washabaugh County"; D. hatcheri is said to belong to Sharps B by Tedford et al. 1985
