I agree. Imagine finding something like a Pachycephalosaurus skeleton without a modern education.

If you're in a pre-civilized, just-barely-scraping-by survival mode, you'd probably conclude: (1) this thing was a monster, and if it lived here I'm not safe. (2) This thing must have been killed by something worse, and if it's around I'm really not safe.
