Drought—not the perils of a muddy bog—may explain why millions of years ago hundreds of large, lumbering meat-eating cousins to Tyrannosaurus rex perished in what is now a dusty, rocky desert in southern Utah.

The site, named the Cleveland-Lloyd Dinosaur Quarry, is one of the world’s most prolific dinosaur fossil sources. It has yielded more than 70 partial skeletons, 12,000 individual bones, and single dinosaur eggs.
