If for some reason you find yourself in Laramie Wyoming. Go to the dinosaur museum on the UW campus. It's not very big but it is worth the trip. Near the back there is a "rock room" behind black curtains. Go in, there is a switch on the left wall that switches on blacklight's so you can see the minerals fluoresce.

Leroy Kameron Durrant, an undergraduate student at the University of Wyoming (UW), reexamined “Reed’s Allosaurus,” a historically significant dinosaur specimen found near Laramie almost 150 years ago. The result was a fascinating insight into a thoroughly plastered prehistoric beast. “There’s plaster and paint over most of the bones, and one bone had three or four metal wires drilled through it,” Durrant told Cowboy State Daily. “But seeing broken bones isn’t fun, so that’s what they did to get it ready for display in the museum.”
