Araripesaurus castilhoi, Lower Cretaceous, the first pterosaur named from this region in northeastern Brazil, is based on only a single partial wing. Its wingspan can be estimated to be about 6.5-8 feet. The specimen is nearly fully grown, and is probably most similar to ornithocheirids like Anhaunguera. Like many other ornithocheiroids, it may have had twin crests near the tips of its jaws. Araripesaurus was likely an aerial fisher, soaring over the waves of the young Atlantic Ocean.
