Prehistoric pronghorn hunting in southwest Wyoming

In the Wyoming Basin of southwest Wyoming, there are more pronghorn-dominat ed bone assemblages and possible communal kill sitez than anywhere else in North America. Ten faunal assemblages in the region are dominated by prongh orn bones (>60% of identified specimens) and sir assemblages possess at lea st sir individuals each. Two of these sites have at least 26 individuals ea ch, and one has at least 212 animals. Three additional sites retain possibl e structural remnants of pronghorn traps. Based on an evaluation of 93 radi ocarbon-dated regional faunal assemblages, it is clear that pronghorn were used commonly, but in low numbers, throughout prehistory. However there was a significant shift in pronghorn hurting about 700 years ago, including an increase in communal hunts and in pronghorn-dominated bone assemblages.
