Nature: Oldest American Artifact Unearthed
Nature Magazine journalist Rex Dalton interviewed SMU archaeologist David J. Meltzer as an expert source to weigh in on the claim by University of Oregon archaeologists who say they've found the oldest known artifact in the Americas.
Dalton's Nov. 5 article, "Oldest American Artifact Unearthed," quotes a number of expert sources on the discovery of a scraper-like tool in an Oregon cave. The discovery team dates the tool to 14,230 years ago.
