Arctodus simus yukonensis, the extinct northern North American short-f
aced bear, is represented by an immature left humerus lacking its unfu
sed proximal epiphysis, which was recovered from a point bar on the lk
pikpuk River, Alaska (69-degrees-41'N, 154-degrees-54'W). This is the
northernmost record of this bear. The specimen is dated at 27 190 +/-
280 BP (IsoTrace TO-2539) on C-14 analysis, which lies within the obse
rved age distribtution of Arctodus. The individual is larger than aver
age for the species based on the dimensions of the distal articulation
, despite its immaturity, and may have been male.
