National Geographic Special: Dinosaur Hunters

More than 80 million years ago, the Oviraptor, a strange bird-like dinosaur, walked the sandy banks of an oasis in what is now the Gobi in Mongolia. A creature that measured some 8 feet in length, its razor-shard claws were deadly weapons of protection for guarding its offspring from constant danger. Now join a daring expedition of scientists as they uncover a treasure trove of fossils, shattering long-held myths about this dinosaur's behavior.
