A fossil packrat midden from 1280 m elevation in the limestone Livingston Hills south of Shafter, Presidio County, Texas, was radiocarbon dated at 15,695 ▒ 230 B.P. (A-1581 on Juniperus). The paleocommunity was a pinyon-juniper woodland with Pinus edulis and 26 associated species. Holacantha stewarti was an important desert species in the paleocommunity. A total of 139 species was recorded in the present xeric Chihuahuan Desert flora near the midden site. Late Pleistocene paleocommunities and the timing of biotic changes in the northern Chihuahuan Desert are discussed.
