Archaeologists just concluded their 2023 field school season at Rimrock Draw Rock Shelter, Eastern Oregon, continuing to push back North America’s timeline through recovery of stone tools and megafauna dating back to 18,000 years ago. Discoveries, in lower layers, include platelets of camel teeth fragments (camels originally evolved in North America and eventually migrated to the Old World). The teeth found at the site were from Camclops, which was native to North America until it became extinct about 11,000 years ago at the end of the last Ice Age.

Below the teeth an orange chalcedony stone tool was found with extinct Bison antiquuis blood found on it during lab analyses using residue analysis (a bison twice as large as todays bison/buffalo!). This tool represents the oldest stone artifact in North America at the present, dating to be 18,000-years-old.
