he Vultursaur, Vultursaurus, is a strange, nocturnal, flying non-avian paravian with bat-like wings from the chasms and jungles of Skull Island. It has a 20-25 inch wingspan. Vultursaurs, despite appearances, are not pterosaurs. In fact they are the sole surviving representatives of a remarkable second dynasty of airborne theropods that have developed bat-like wing membranes instead of feathered wings. Their wings (which are not single sheets of skin as on pterosaurs) are divided by extended fingers like bats. Broad and supple, their wings are able to be realigned with ease in flight. Their flapping is not as efficient as either a bird’s or bat’s but is more than sufficient to keep them aloft.
