Hatzegopteryx thambema

With an estimated wingspan of 12 m, Hatzegopteryx was a very large azhdarchid pterosaur from the late Cretaceous of Romania. It is known from fragmentary remains which include skull fragments. The skull is characterized by its large size (initially estimated to be nearly 3 m in length) and its robusteness.
