Five cobbles displaying use-wear and impact marks were also recovered from the site in Bed E. The research team found cobbles and broken mastodon bones lying together at the site.

The research team claims that the cobbles found at the site were used as hammerstones and anvils. The research team also claims that the mastodon bones show signs
