Environment
Lithology: sandstone
Habitat comments: "unconsolidated sand"
Methods
Life forms: carnivores,rodents,other small mammals
Sampling methods: screenwash
Sample size: 17 specimens
Museum: SDSM
Sampling comments: "derived from nearly one-half ton" of screenwashed matrix
quarrying occurred over "three seasons" at some point from 1953 on, but the exact date is not given
not the same as the earlier SDSM Museum of Geology Mission collections from the same general locality reported by Macdonald (1960), which derived from a salvaging operation
a newly reported Aelurodon is from this collection and not the earlier one based on its catalog number
additional specimens from "a calcareously cemented lens" called Mission Ledge, above Mission Quarry, are listed
