Fossil bones from Sawmill Sink
Fossil bones from Sawmill Sink, a 100-foot-deep flooded sinkhole on Great Abaco Island that contains the fossil bones of more than 60 bird species including Caracara creightoni, osprey, American kestrel and likely Cooper’s hawk. The dark, oxygen-free depths of the sink hole provided ideal preservation conditions for the bones.
This research was supported by the National Science Foundation (grants BCS 1118369 and BCS 1461496).
