These bones tell of Native American hunting long ago showing stone points imbedded in animals killed. Shown is a Lakota-type arrowhead on the inside of a young buffalo, meaning an arrow traveled through from the other side. Next is a buffalo skull with a point still in the bone, but was broken off. Its size indicates it was a spear point, which would be thrown with an atlatl. The bottom row shows a bear skull and a deer's vertebrae with small arrowheads imbedded.
