Ice-Age Carving of Mammoth or Mastodon Found in Florida

Researchers have identified a carving of what appears to be a mammoth or a mastodon in a bone fragment, estimated to be at least 13,000 years old.

The engraving, approximately 13,000 years old, is 3 inches long from the top of the head to the tip of the tail, and 1.75 inches tall from the top of the head to the bottom of the right foreleg. Chip Clark/Smithsonian
