Environment
Substrate: ground surface
Lithology: claystone
Taphonomic context: fissure fill
Habitat comments: from "a series of localized, sediment-filled cavities formed in the underlying Harleyville Formation and Santee Limestone. Groundwater had preferentially dissolved away the upper portions of the Santee Limestone, so that many of the solution cavities contacted the overlying, clay-rich Harleyville Formation. This resulted in the occasional collapse of the Harleyville Formation, opening several of the cavities to the surface. The diameter of the solution cavities varied from a few centimeters to a maximum diameter of nearly 2.0 m. The solution cavities reached a maximum depth below the Harleyville Formation of about 4 m... The sediment is well-stratified and ranges in size from clay to small pebbles"
Methods
Life forms: carnivores, rodents, ungulates, other large mammals, other small mammals
Sampling methods: quarry, screenwash, surface
Sample size: 485 specimens
Net or trap nights: 0
Basal area status: not applicable
Sampling comments: "We collected fossil material from the surface of associated spoil piles as well as by screen sifting from the fossiliferous sand. Screens used were 20 gauge (1.0 mm) to quarter-inch (6.35 mm) mesh" and material was collected "in situ"
