Azhdarcho is a genus of azhdarchid pterosaur from the late Cretaceous Period of the Bissekty Formation (middle Turonian stage, about 92 million years ago) of Uzbekistan, as well as the Zhirkindek Formation of Kazakhstan and possibly also the Ialovachsk Formation of Tajikistan. It is known from fragmentary remains including the distinctive, elongated neck vertebrae that characterizes members of the family Azhdarchidae, a family that includes many giant pterosaurs such as Quetzalcoatlus. The name Azhdarcho comes from the Persian word azhdar (), a dragon-like creature in Persian mythology. The type species is Azhdarcho lancicollis. The specific epithet lancicollis is derived from the Latin words lancea (meaning "lance" or "spear") and collum ("neck"). Most individuals were relatively small with an estimated wingspan of , but some remains indicate a larger wingspan of .

==History== thumb|Neck vertebrae (third from the bottom) compared to those of other Azhdarchids The fossil remains of Azhdarcho were recovered in the Kyzyl Kum desert (from the Taykarshinskaya unit of the Bissekty Formation) by Lev A. Nesov during expeditions to Central Asia in 1974–1981. The type specimen, given the catalog number ЦНИГРмузей 1/11915 (TsNIGRmuzey), consists of an anterior neck vertebra. Twelve paratypes were referred, including several other neck vertebrae, elements from the wing and leg, and pieces of the jaw. These specimens, along with other vertebrate fossils collected during the expeditions, were deposited at the F.N. Chernyshev Central Geologic Exploration Museum in St. Petersburg.
