A geoarchaeological evaluation of a reported late Pleistocene human burial from Brazoria County, Texas

The skeleton of a human adult female was excavated from alluvial sediments along the Gulf Coastal Plain of Texas. She was buried face down in an extended position with her hands crossed beneath the waist. Initial radiocarbon ages indicated that this skeleton dated to the late Pleistocene. Geoarchaeological and archaeological excavations at the site, coupled with new radiocarbon ages, amino acid compositional data, and an analysis of the previously reported radiocarbon ages obtained from the skeleton instead suggest a middle Holocene age for this burial.
