This biface was recovered from the Wullschleger site in Marshall County and donated to the Kansas Historical Society in 1961. A biface like this one could have been used as a chopping tool or, with more work, turned into a specific tool. The style is similar to a type of biface archeologists call Munkers Creek bifaces. The Munkers Creek phase describes a stone tool technology restricted primarily to the Flint Hills from 4000 to 3800 BCE.
