The "Lightning Claw"is a large theropoddinosaur from the Cretaceous period of Australia. It has no scientific name as of now, but its nickname originates from the site of its discovery, Lightning Ridge, and the animal's massive hand claws. It is one of the largest carnivorous dinosaurs found in Australia, reaching lengths of around twenty feet. It is part of a family of large, carnivorous dinosaurs known as Megaraptora. Due to the fact that it is twelve million years older than the previous oldest megaraptorid known from Australia, it is helping to overturn the notion that Australia was an evolutionary backwater for dinosaurs and also suggests that the megaraptorids might have originated in Australia. It is possible that this animal is synonymous with Rapator, an Australian megaraptorid known only from a few bones.
