New dinosaur discovery solves evolutionary bird puzzle
Pretty interesting stuffA newly discovered fossil has shed light on why a group of dinosaurs looks like birds, say scientists. Haplocheirus sollers may not be as charismatic as T. rex or as agile as a pterodactyl but it's thought to solve a long standing puzzle. Researchers believe its short arms and large claw show how bird-like dinosaurs evolved independently of birds. The 3m-long skeleton, found on an expedition to China's Gobi desert, is described in the journal Science.
