A group of scientists have found a mammoth bone at a dig site in southern Iowa's rural Mahaska County.
The group was cleaning up mud and other debris when they made the discovery Saturday.
Researcher Holmes Semken tells the Oskaloosa Herald that the bone shows evidence of fractures.
The newspaper reports the scientists are preparing the dig site for a visit from a group out of the University of Kansas. They do geoarchaeological research for evidence of early humans.
