- Comments
- MlVl-13, Old Crow River Locality HH69-21: The dated bison bone exhibits cut-marks made by stone tool (Morlan, 1980: Pl. 7.3, 1986: Fig. 3), and the date provides important geochronological control for Disconformity A. Dr. Pat Shipman provided confirmation of the cut-mark interpretation by performing a scanning electron microscope analysis (see The Mammoth Trumpet, Vol. 1, no. 1, 1984).
