Beijing, CHINA: Dinosaur hunter Xing Xu (L) briefs the media on the fossilized bones of a gigantic theropod dinosaur, Gigantorraptor Erlianensis, on display for the media in Beijing, 13 June 2007, after the remains of a gigantic, surprisingly bird-like dinosaur was uncovered in Inner Mongolia, China. The animal, which lived in the Late Cretaceous period (about 70-million years ago), is thought to have had a body mass of about 1,400-kilograms, which is surprising as most theories suggest that carnivorous dinosaurs got smaller as they got more bird-like. The dinosaur, which is described in this week's issue of the the magazine Nature, has been classed as a new species and genus. Animal on display is a miniature model. AFP PHOTO/ Frederic J.
