Ficus Pit (Pleistocene to of Bahamas)

Where: San Salvador, Bahamas (23.9° N, 74.6° W: paleocoordinates 23.9° N, 74.6° W)

• coordinate estimated from map

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

• The depth from ground level to the sediment floor is 9.7 m (32 feet), the floor being roughly circular, with a diameter of about 7 m, the opening at the surface being smaller. The bottom of the pit is considerably overhung by what appears to be the remains of a higher floor, suggesting that an earlier sink formed that later collapsed into one beneath it

Environment/lithology: sinkhole; lime mudstone

• There was no apparent stratification except that a dark organic upper layer (-10-20 cm thick) overlay a yellowish, limey sediment of varying thickness. The considerable amount of roof-fall complicated digging and contributed to mixing of specimens of different ages when bones would fall into spaces between rocks.

Size classes: macrofossils, mesofossils

Preservation: bone collector

Reposited in the USNM

Collection methods: surface (in situ), sieve,

• The floor underneath an overhang on the north wall was the site of a recent Barn Owl (Tyto alba) roost, with prey remains from regurgitated pellets scattered about the surface and into the loose, organic surface sediment. We collected these remains and dug three trenches and two additional test pits in the sediments of the floor. Sediment was passed through one quarter inch mesh and window screen.
