A WALK IN THE AZDARCHID... by SharkeyTrike on DeviantArt Azhdarchidae is a family of pterosaurs known primarily from the late Cretaceous Period. Azhdarchids included some of the largest known flying animals of all time. Originally considered a sub-family of Pteranodontidae, Nesov (1984) named the azhdarchinae to include the pterosaurs Azhdarcho, Quetzalcoatlus, and "Titanopteryx" (now known as Arambourgiania).
