DOCUMENT
Full-Text
A broken boulder that may have been used as a stone tool (maul) was submitted for protein residue analysis. This tool was recovered from the National City Mastodon Site in National City, a southern suburb of San Diego, California. The rock was found among broken mastodon bones. If this boulder was used to process plant or animal remains, identifiable proteins may be present in the micro-crevices on its surface.
