Notes On Bison In Val Verde County,Texas: Additions To Dillehay

Abstract

Bison remains from deeply stratified deposits at the Castle Canyon Site, an area of southwestern Texas where bison remains are outstandingly rare, date about 1500 B.C.-A.D. 1000. The last bison known in the area died about 1885. It is suggested that environmental conditions in the area may not have changed, and that presence-absence periods might rather reflect changing conditions on the Central or Northern Plains. These data do not alter Dillehay’s conclusions, but present information not available to him.
