==Discovery== Alamodactylus is known solely from its holotype, SMU 76476, a partial left wing first described by Myers (2010). This specimen is crushed and consists of a left humerus, the distal end of the fourth wing metacarpal and the proximal end of the first wing phalanx of fourth digit. Other elements of the holotype first reported by Andres and Myers (2013) include a left proximal syncarpal, manual phalanx, and some fragments including four tapering processes that may represent skull bones, an articular surface that appears to be the mandible articulation of the right quadrate as well as thin bones that do not taper and may be ossified tendons. Alamodactylus was first named by Brian Andres and Timothy S. Myers in 2013 and the type species is Alamodactylus byrdi. The generic name is derived from Alamo – symbol of Texas independence and dactylos, meaning "finger" in Ancient Greek which is a traditional suffix for pterosaur genera in reference to their elongate wing digits. The specific name, byrdi, honors Gary Byrd for discovering the holotype. The holotype was collected from the Atco Formation of Austin Group, north of Dallas in Collin County, dating to the lower Coniacian stage of the middle Late Cretaceous period, about 89.8–88 million years ago.
