We'll track down the largest beasts ever to tread on the earth, over 100 million years ago - the Stegosaurus, the Velociraptor, the Brontosaurus, and the Tyrannosaurus Rex. We'll start with a drive to Glenrock, Wyoming for a hands-on dig with one of the world's most famous paleontologists, Dr. Robert Bakker. After several days of discovering triceratops bones, fossil fish and more, we'll follow Dr. Bakker down to Medicine Bow.
