Controversial engraved piece of deer bone from Jacob's cavern. The design has been interpreted as a Mastodon. The sharp and bold lines do not find examples from other Paleo-Indian or Archaic sites in Missouri. My opinion (Professor Michael Fuller) is that the bone is old but the design was engraved, recently.
