The petroglyphs were placed there many millennia after the tracks were made, seems our ancient ancestors were a curious bunch too.
It's quite a marvel to imagine that these ancient people might have had some understanding of the significance of these fossil records, even if they likely didn't comprehend the exact origins of the tracks. After all, humans and dinosaurs existed millions of years apart. The term "dinosaur" itself only came into use relatively recently, a significant chunk of time after the dinosaurs' reign had ended.
..And they may well have learned to respect the dinosaurs through personal contact.. LOL
So far as the term "dinosaurs", I doubt it was being used when dinasaurs were actually walking about in abundance.
Paluxey river has some imput also.
