Horner takes kids along on the dig, explaining step by step how fossils are formed, the best places to find them, what it takes to get them out of the ground, and what the fossils tell us about the dinosaurs that roamed the Rocky Mountain states and the Dakotas. We even get to look back in time at what the region looked like during the Mesozoic Era and what dinosaurs ruled in what are now Montana, Colorado, Utah, Wyoming, Idaho, North Dakota, and South Dakota.
