Paleontologists have discovered a new wildly snaggle-toothed skull in northeast China that belonged to previously unknown flying reptile. It was named Guidraco venator, which is Chinese and Latin for “ghost dragon hunter” by the carnivorous pterosaur had a wingspan of 13 to 16 feet, a jaw filled with pointy teeth, and a round sail on its head to stabilize its flight.   The lithe, feathered, predatory dinosaurs known as raptors were mainly confined to late Cretaceous North America and Eurasia, but a few lucky genera managed to cross into the southern hemisphere. To date, Austroraptor is the largest raptor ever to be discovered in South America, weighing about pounds and measuring over 15 feet from head to tail--still not .

The skeleton of the Asteroidea is composed of a vast number of small calcareous plates, or ossicula, united together by the coriaceous perisome, so as to form a species of chain-armour. Besides these, the integument is abundantly supplied with spines, tubercles, and "pedicellariae.".
