2-C DISCOIDAL
MAMMOTH BONE FLAKE Of particular interest is this round flake that was struck from a portion of the mammoth's long bone. The point of impact or bulb of percussion can clearly be seen at the top right of the hand held picture. It would take a single hard strike with a hammer stone to remove this type of flake. The lower picture shows a triple exposure of this artifact. A bulb of percussion can be see on the center edge picture and the picture to the left. |
