How did those enormous dinosaur skeletons get inside the museum? Long ago, dinosaurs ruled the Earth. Then, suddenly, they died out. For thousands of years, no one knew these giant creatures had ever existed. Then people began finding fossils -- bones and teeth and footprints that had turned to stone. Today, teams of experts work together to dig dinosaur fossils out of the ground, bone by fragile bone. Then they put the skeletons together again inside museums, to look just like the dinosaurs of millions of years ago.

Dinosaurs from one to ten use construction equipment to dig, shovel, roll, and scrape as they build a fun surprise.

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!

This is the story of Earl Douglass and his discovery of the first almost complete skeleton of an Apatosaurus, one of the largest dinosaurs ever to roam Earth.

With a lively rhyming text and vibrant paper collage illustrations, author-artist Bob Barner shakes the dust off the dinosaur bones found in museums and reminds us that they once belonged to living, breathing creatures. Filled with fun dinosaur facts (a T. Rex skull can weigh up to 750 pounds!) and an informational "Dinometer," Dinosaur Bones is sure to make young dinosaur enthusiasts roar with delight.

In the Badlands of Montana, many stories are waiting to be told – about Triceratops and Ankylosaurus and ancient crocodiles. There, scientists search for the bones of animals that lived millions of years ago. In Dinosaur Dig, Kathryn Lasky and Christopher G. Knight, the award-winning writer-and-photographer team, describe the dirty, sweaty, and exciting job they and five other families perform as they search for fossils in the Badlands. Dinosaur Dig is a feast of keen observation, magnificent photography, and information about Earth’s ancient past. Like any good story, it captures expectations and disappointments, close calls, and finally success as the diggers uncover and race to preserve the bones of a creature that died 67 million years ago.
