A funny thing about this find is that the bone was in a core from beneath the parking lot of the Denver Museum of Nature and Science which is heavily dinosaur focused. It’s either a crazy coincidence or there are abundant dinosaurs under Denver.
There are a lot in the area. There is dinosaur ridge out on i-70 that features all sorts of dino tracks and fossils. There was also another fossil discovery during while building a shopping center not too long ago: https://www.colorado.edu/coloradan/2017/10/10/dinosaur-found...
Many major US cities have museums like this. It wasn’t built there because of the dinosaur archaeology as far as I know. This core was found during unrelated digging in the parking lot of the museum, so I think it is a coincidence.
> This phenomenon is not uncommon in the metropolitan Denver area where such discoveries have catalyzed public curiosity in subsurface geology for nearly 150 years
That sounds like it’s the latter. But actually, it’s both!
