Pendejo Cave early occupation evidence

Record summary

Pendejo Cave was reported as containing human-related evidence in deposits assigned to the late Pleistocene, including modified materials and traces interpreted as possible human activity. Some claims implied an occupation older than the conventional Clovis horizon, while other researchers questioned the identification of marks and the security of associations. The site matters for comparing cave taphonomy, radiocarbon dating, and criteria for recognizing human use when artifacts are sparse. Important uncertainties concern contamination, redeposition, and whether alleged modifications are cultural or natural.
