The Search for Late Pleistocene pre-Clovis Archeology in Texas: Problems and Potentials
MetadataShow full metadata
Geoarcheological research in the North Sulphur River valley demonstrates the presence of an alluvial sequence that spans 17,000 years and provides the first radiocarbon dates for the Lower Sulphur River Formation. Stone artifacts and a single bone were discovered on the eroded surface of the Lower Sulphur River Formation and might represent a pre-Clovis occupation. Before such a claim can be made, in situ artifacts must be documented in these Late Pleistocene sediments. If pre-Clovis occupations exist anywhere in Texas, systematic geoarcheological investigations must target and identify Late Pleistocene deposits older than 11,050 B.P., then careful archeological searches must focus on these sediments.
