Coelurosauravidae
One of the three main groups of flying vertebrates found in the Different World, Coelurosauravids are a medium-sized family of small to large reptilians, physically resembling lizards, specifically Draco lizards. Mostly carnivorous, feeding on insects or carrion with some active hunters of large animals, with a few herbivorous species, Coelurosauravids fly with the use of spines connected with skin membranes with powerful muscles at the base to allow for powered flight.
