''Anhanguera robustus'' is a large pterosaur species known from fossil remains dating to the late Cretaceous Period of South America. ==Description== ''A. robustus'' is based on several specimens, including the holotype (BSP 1987 I 47), consisting of a complete lower jaw, and additional referred specimens representing more of the skull and upper jaw. As in other ornithocheirids, both the upper and lower jaw bore thin, rounded, projecting crests. The lower jaw crest of ''A. robustus'' had relatively steep front and back edges, was short front to back but tall from top to bottom. Like other species of ''Coloborhynchus'', the jaw was flared and expanded toward the end, and the tip was blunt and triangular in cross section, with teeth angled outward and downward. The upper jaw crest had a distinctively concave front edge.〔Veldmeijer, A.J., H.J.M. Meijer, and M. Signore (2006).
