无数的阿兹达克翼龙化石，在过去的二十年里，在德克萨斯州佩科斯山外的大弯国家公园的晚白垩世（马斯特里赫特期）岩石中发现了一些化石。在一个地方发现的200多块骨头中，有四块不完整的头骨和下颌骨，这提供了关于阿兹达尔科头骨结构的最完整信息。目前已知的资料表明，Azhdarchidae是巴西东北部早白垩世沉积物中Tapejaridae的姐妹群。
Numerous remains of the azhdarchid pterosaur Quetzalcoatlus sp., have been recovered over the last twenty years from the Late Cretaceous (Maastrichtian) rocks in Big Bend National Park in Trans-Pecos Texas. Among more than 200 bones found at one locality are four incomplete skulls and mandibles, which provide the most complete information about cranial structures in the Azhdarchidae. What is currently known indicates that the Azhdarchidae is the sister group of the Tapejaridae from Early Cretaceous deposits in northeastern Brazil.
