A compelling account of how the impact of a giant asteroid may have killed the Earth's dinosaurs.

After the age of the dinosaurs, strange and powerful mammals ruled the earth. . . .

Written for kids ages 8 to 12, "Digging Up Dinosaurs" is chock full of fun and fascinating information about fossils in Montana, Colorado, Utah, Wyoming, Idaho, North Dakota, and South Dakota. 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 days of dinosaurs!
