The Pterosaur Flock of the Overworld

The Pterosaur Flock of the Overworld: As Phantoms landed back onto Earth after millions of years, a species split from their original ancestors and became Earth adapted. Despite loosing lots of mass, they gained more attributes. They fly together in large massive flocks. Very much like their cousins, they eat zombies away into skeletons, but instead do it with more mobs. They are very dangerous to encounter when they are hungery.
