Bakiribu (lit.'comb') is an extinct genus of ctenochasmatid pterosaurs known from the Early Cretaceous (AptianAlbian age) Romualdo Formation of Brazil. The genus contains a single species, Bakiribu waridza, known from the fragment remains of two individuals preserved in a regurgitalite. This indicates the pair may have been consumed by a spinosaurid theropod dinosaur. It represents the first member of the broader clade Archaeopterodactyloidea described from the Romualdo Formation. Bakiribu has a unique pattern of closely-packed comblike teeth in the upper and lower jaws that may have been used for filter feeding, similar to the closely related Pterodaustro.
