The author examines bone processing in autochthonous assemblages of coprolites and fossil bone, representing about 80,000 years of early Oligocene deposition and bone accumulation, from volcaniclastic floodplain sediments of the Orella Member of the Brule Formation (White River Group) in northern Sioux County, Nebraska. The samples were collected using brooms to sweep fossiliferous surface litter from small areas within University of Nebraska State Museum (UNSM) localities Sx-6 (0.08 km2) and Sx-7 (0.05 km2) during 1989-1991. The coprolites (n = 1250) contained teeth and bones of didelphid marsupials, lagomorphs, camels, oreodonts, leptomerycids, hypertragulids, and canids. Based on their si...
