Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.
