TABLE 3. NISP and relative abundances (% NISP) for fossil mammal species from the Morgan’s Cave test pit and Barrow Island owl pellet (BWI OP) material. “-” indicates species not recorded in a spit. “X” indicates species that are present on Barrow Island (Abbott and Burbidge, 1995) but are not present in the owl pellet material.
