Comments
DkLw-VP, Waggle Springs: The horn core was examined by M.C. Wilson who found it to be the right horn core of a mature male bison. The horn core is long and robust, exhibiting prominent exotoses suggesting an age at death of 10 or more years. Too little of the skull is attached to determine the angle of deflection, an important character from a taxonomic standpoint. However, the vertical diameter at the base of the horn core (100 mm), the transverse diameter at the base (105 mm) and the circumference at the base (335 mm) are very close to the maxima for B. bison occidentalis and are more typical measurements for B.b. antiquus.
