In 1897, paleontologist Walter Granger was exploring in Wyoming when he found a cabin built with dinosaur bones gathered from the ground nearby. He followed the trail back to a hillside littered with fossils and realized the area was an extraordinary bone bed, later named Bone Cabin Quarry. That discovery opened one of the richest dinosaur dig sites in the American West, producing huge numbers of Jurassic fossils over the years that followed.
