Odd how the Navajo would have such a legend when the time span is so great and there was no possible overlap between this creature and humans. Unless we're wrong about the time span.
That was interesting, but based on their earlier discovery of the same fossil. In Roman times Augustus (I think it was) traveled out to see an accidental discovery (someone was digging a foundation or something) of what was apparently a large fossil of some sort (whale, dino, whatever) somewhere in Greece, or maybe near modern Greece in the Balkans, and acknowledged the spot as the final resting place of some legendary giant, or Hercules, or somethin’. Okay, yeah, that story kinda meandered...
