The rock art of Dinosaur National Monument is not found in direct association with the fossilized remains that made it famous, but there is certainly a large quantity of it in that area. I cannot imagine that there not a connection. Rock art portrays the beliefs and events of a society, and in an area with both fossilized dinosaur remains and world class rock art the creators of the rock art must have been aware of the amazing bones.
As I said, this has been a sub-theme of my personal interest for a long time. Indeed, the photo of giant lizard petroglyphs in my page heading comes from Cub Creek in Dinosaur National Monument, and I have since associated them with a dinosaur fossilized track site nearby, but that is for future postings.
