Geography
Country: United States
State: Tennessee
County: Overton
Coordinate: 36° 17' 25" N, 85° 22' 25" W
Latlng basis: stated in text
Time interval: Late Pleistocene
Geography comments: "on the Walter Robinson farm about 8 miles southwest of Livingston... altitude c. 1200 feet"
thought to include some material as old as "late Sangamon/early Wisconsin" age and to span "a rather long period of accumulation", but "The fauna as a whole indicates a temperate/boreal, probably open, woodland" instead of a mix of environments
