Upper Pasture Cave, Little Exuma (Pleistocene of Bahamas)

Where: Bahamas (23.4° N, 75.6° W: paleocoordinates 23.4° N, 75.6° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• The presence of extinct species, such as the gigantic hawk Titanohierax, combined with the heavy mineralization of the specimens from the Little Exuma deposits, probably indicates a Pleistocene age, but as with most Antillean cave deposits, there is little direct evidence for dating.

• bed-level stratigraphic resolution

Environment/lithology: cave; limestone

Size class: macrofossils

Collected by V. Knowles in 1937; reposited in the MCZ
