Coloborhynchus araripensis

''Coloborhynchus araripensis'' is a pterosaur species from the Aptian-age Romualdo Member of the Lower Cretaceous Santana Formation, of Barra do Jardim, Araripe Plateau, Ceará Province, Brazil. ''C. araripensis'' was named after the Araripe Plateau.
==Description==
''C. araripensis'' was a large species originally based on BSP 1982 I 89, known as the "Munich specimen", fossil remains including a partial skull (missing the end of the jaws) and arms; the preserved skull section had no evidence of a crest. A more complete skull, catalogue number MN 4735–V, has been referred to the species and has shed light on the anatomy of the jaw tips, important in ornithocheirid classification. An additional referred specimen, known as the "St. Gallen specimen" (SAO 16494), consists of a nearly complete skull.
Using the referred specimens as a guide, ''C. araripensis'' has been described as similar in skull anatomy to species referred both to ''Anhanguera'' and ''Coloborhynchus'', and the species is placed in either of these genera by various researchers. Like other species referred to ''Coloborhynchus'', the snout tip was blunt and bore two forward-projecting teeth that emerged higher on the jaw than the rest of the tooth row. As in most other ornithocheirids, the species bore a large, rounded crest at the tip of the jaws. Like ''Coloborhynchus'' species and unlike the type species of ''Anhanguera'', the crest emerged from the very tip of the blunted jaws, rather than further back on the jaw. However, unlike the type species of ''Coloborhynchus'', ''C. araripensis'' lacked a dent or depression in the blunted jaw tip, and the teeth appear to have been smaller and more uniform in size.〔Veldmeijer, A.J., H.J.M. Meijer, and M. Signore (2006). "''Coloborhynchus'' from the Lower Cretaceous Santana Formation, Brazil (Pterosauria, Pterodactyloidea, Anhangueridae); an update." ''PalArch’s Journal of Vertebrate Palaeontology'', 3(2): 15-29.〕
