Geography
Country: United States
State: Pennsylvania
County: York
Coordinate: 40° 1' 0" N, 76° 43' 30" W
Coordinate basis: stated in text
Time interval: Pleistocene - Holocene
Ma: 0.003722
Age basis: radiocarbon (uncalibrated)
Geography comments: "altitude 350 feet... one-quarter mile east of Emigsville, Manchester Township
there is a "carbon14 date" of "3,722 +/- 200 years (Before Present)" and the fauna is interpreted as spanning the "Late Glacial", "Hypsithermal", and "Recent" based on faunal interpretations (presumed to be uncalibrated because the error is symmetrically distributed)
there are several cold-climate rodent species, but the only substantial evidence of a Pleistocene age is the presence of Rangifer tarandus

Environment
Lithology: breccia
Taphonomic context: cave
Habitat comments: "The breccia occurred as a ledge... Varying from 0.13 meter to 1.2 meters thick... composed of a matrix of angular, irregular blocks of unweathered dolomite (80 per cent)... rounded, well-weathered limonitic sandstone pebbles" and "brown, sandy, unconsolidated loam, all bound together with travertine"
Methods
Life forms: bats,carnivores,rodents,ungulates,other small mammals
Sampling methods: quarry,screenwash
Sample size: 159 specimens
Years: 1963
Sampling comments: "Approximately 1.5 square meters were removed by wedging and dynamiting... many of the loam inclusions... were washed to recover such minute items as insectivore teeth"
millipedes, snails, salamanders, frogs, a turtle, and snakes are listed but not inventoried
