Geography
Country: United States

State: South Carolina

County: Dorchester

Coordinate: 33° 14' N, 80° 26' W
Latlng basis: stated in text

Time interval: Late Pleistocene

Ma: 0.01894

Age basis: radiocarbon (uncalibrated)

Geography comments: "late Rancholabrean... in the Giant Cement Plant pit... 5 km north-northeast of Harleyville"
"Dating was done on apatite... fossil material... were dated at 18.940 +/- 760 y.b.p." (presumed to be uncalibrated because the error is symmetrically distributed)

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"
