This broken basal notched biface was found in Bell County, Texas. It was made with similar percussion flaking as the Sweetwater Biface and is every bit as thin. What makes this artifact interesting is the center hole broken out from large percussion flakes that dove inward. It's rare to see an isolated hole in the center of a biface like this example and not broken apart. The flaw in the stone below the hole probably caused the biface to break in half. It measures 3 1/2 inches long and 3 5/8 inches wide.
