Overview

Hype:

Cleveland-Lloyd Dinosaur Quarry contains the densest concentration of Jurassic-aged dinosaur bones ever found. Over 12,000 bones (belonging to at least 74 individual dinosaurs) have been excavated at the quarry. Cleveland-Lloyd Dinosaur Quarry has helped paleontologists learn a great deal about the Jurassic period, yet the site presents at least as many mysteries as it helps to solve. Curiously, more than 75% of the bones come from carnivores, primarily Allosaurus fragilis. With more than 46 individual specimens of Allosaurus, scientists have been able to deduce much about how Allosaurus aged and compare individuals to better understand intraspecies diversity. Yet the sheer density of bones proposes many questions. How did the carcasses of so many animals end up in one place, and why are most of them meat-eaters? While many good hypotheses have been presented, they all still have major flaws - the mystery has yet to be solved.

I was in the area for work, so I decided to check out the quarry. The museum was small but well done.
