Stegosaurus, Triceratops, Brontosaurus, Tyrannosaurus...these exotic prehistoric creatures continue to fascinate more than 200 million years after they last roamed the earth. Dinosaur skeletons have been reconstituted, reconstructed, and interpreted by scientists and artists since the first fossils were uncovered near Ca on City, Colorado, in 1877, sparking the Bone Wars. In 1907, the Carnegie Museum of Natural History mounted Dippy the Diplodocus, which sparked dinomania, igniting the imagination of popular culture and Hollywood. From the Morrison Formation to Montana's Hell Creek, and from Mongolia's Gobi Desert to Argentina's Patagonia, new discoveries and excavations have uncovered a lost kingdom that has inspired myriad homages.
