Although there have probably been dinosaur discoveries dating back thousands of years -- there are, for instance, references to "dragon bones" found in ancient China -- the first documented dinosaur discovery took place in 1676 when a jawbone and teeth were unearthed in Oxford, England. In 1824, famed paleontologist William Buckland (1784-1856) finally named this first dinosaur Megalosaurus. Megalosaurus was a large meat-eater that stood up to 9 meters (30 feet) tall and weighed about 1 ton.
