Pterosaurs are rare components of Texas Cretaceous faunas. The best known is Quetzalcoatlus northropi, from the Javelina Formation (Maastrichtian) of Big Bend National Park, with a wingspan of some 11-12 m (Lawson, 1975; Langston, 1986; Busbey and Lehmann, 1989). Texas pterosaur specimens of less spectacular proportions include a pteranodontid partial humerus (USNM 13804) from the Eagle Ford Formation (late Cenomanian-late Turonian) of Austin (Gilmore, 1935; Bennett, 1989) and a first wing phalanx of a pterodactyloid from the Buda Formation (Cenomanian) of Hays County (Langston, 1974; Lawson, 1975). Pterosaur bones were also recorded at localities near Forestburg, Montague County (Zangerl and Denison, 1950), in the Antlers Formation (Winkler et al., 1990), although these specimens are undiagnostic hollow bone fragments.
