A Vultursaurus is a small flying theropod that lives in Skull Island.
Wingspan: 20-25 inches
Although it is very similar to a pterosaur, the Vultursaur is actually a theropod dinosaur- this is an example of parallel evolution. The wing are identical to a bat's, consisting of skin spanned between strongly elongated 'wing finger', with two normal wings located at the front. This design is also similar to pterosaur wings, although these have only one wing finger.
The Vultursaur also has a short tail and powerful, bird hind legs with an opposable toe. Its fearsome looking head sports large eyes and eardrums, as well as needle-toothed jaws ending in a small beak. As indicated by its large eyes and eardrums, the Vultursaur is nocturnal, living in Skull Island's dark ravines where it roosts during the day. At night, it emerges to hunt insects in great numbers.
Vultursaurs are not great fliers, but fly well enough to catch their prey. They are heavily preyed upon by other ravine-dwelling species - a single Deplector can eat several dozen a night.
