El Bosque (Pleistocene of Nicaragua)

Where: Nicaragua (13.3° N, 86.5° W: paleocoordinates 13.3° N, 86.5° W)

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

Environment/lithology: lacustrine; green claystone

• "green clay" thought to represent a "swamp or pond"; series of six dates gave unreliable results due to lack of collagen, contamination, and leaching; locality thought to be earlier than late Wisconsinan based on this and on geomorphology; see also Gruhn 1978

Collection methods: quarrying
