Spiral Fractures and Bone Pseudotools at Paleontological Sites
Spiral ('green bone') breakage has been suggested as an indicator of human activity by some workers. Our examination of broken ungulate long bones from six paleontological localities in western Nebraska, however, shows that such fractures commonly occurred in the Miocene and Pliocene, long before the advent of man in North America. Pseudotools also occur frequently in these sites. We postulate that spiral breakage, including the production of pse…
Taphonomy and Population Dynamics of an Early Pliocene Vertebrate Fauna, Knox County, Nebraska
The principal purpose of this study is to determine from geological and biological evidence how a concentration of fossil bones originated. The Verdigre quarry of earliest Pliocene age in the Valentine Formation, northeastern Nebraska forms the basis for the investigation. Some 40 genera of mammals, 7 of reptiles, 2 of amphibians, and 6 of fishes are represented in a collection of over 20,000 identifiable specimens recovered from a small excavati…
