Azhdarchidae

(Nessov 1984)

Azhdarchidae is a family of pterosaurs known primarily from the Late Cretaceous. Azhdarchids include the largest flying animals discovered, but smaller cat-size members have also been found. Originally considered a sub-family of Pteranodontidae, Nesov (1984) named the Azhdarchinae to include the pterosaurs Azhdarcho, Quetzalcoatlus, and Titanopteryx. They were among the last known surviving members of the pterosaurs, and were a rather successful group with a worldwide distribution. Previously it was thought that by the end of the Cretaceous, most pterosaur families except for the Azhdarchidae disappeared from the fossil record, but recent studies indicate a wealth of other pterosaurian fauna based on several pteranodontian fossils from the latest Cretaceous period.
