This bison bone rasp was recovered from the Bell village site in Comanche County. It was made by cutting grooves into a bison rib. Archeologists believe that artifacts like these could have been used as musical instruments by drawing a stick across the grooves. The Bell site is a Middle Ceramic period, Wilmore complex site occupied by people who gardened, fished, and hunted, primarily bison in south central Kansas and north central Oklahoma. The site was the focus of the 1984 Kansas Archeology Training Program field school.
