Abstract:	Two avian footprints discovered in the Grotto Beach Formation (Pleistocene) of San Salvador Island (Bahamas) are the first known vertebrate trace fossils on this well-studied island. The trace fossils, preserved as beddingplane impressions in an oolitic-bioclastic grainstone, match the size and form of tracks made by modern gulls. The tracks are in beach facies located below a paleosol dated from Marine Isotope Substage 5e (~120,000kya). These tracks add to a record of Pleistocene bird tracks reported from Eleuthera Island and bode well for the recognition of more vertebrate trace fossils on San Salvador and other Bahamian islands.
