Excavation of the Sheaman Clovis site in eastern Wyoming by University of Wyoming in the late 1970s produced one radiocarbon age of uncertain relationship to the Clovis level and one age on bone of poor reliability. New excavations in 2000 recovered additional material for radiocarbon dating as well as a Clovis elongated flake multiple use tool at the base of a black, cumulic A horizon. This paper presents evidence of an age of ca. 11,200 ± 50 yr B.P. for the Clovis occupation, and an Allerød‐Younger Dryas age for the paleosol, along with a detailed description of the Clovis tool. © 2004 Wiley Periodicals, Inc.
