Bakiribu

Bakiribu is an extinct genus of pterosaur known from the Early Cretaceous Romualdo Formation of Brazil, containing the single species Bakiribu waridza. It was initially described as a ctenochasmatid pterosaur based on remains interpreted as the fragmentary jaws of two individuals preserved together in a regurgitalite, suggesting the pair may have been consumed and regurgitated by a spinosaurid theropod dinosaur. Under this interpretation, Bakiribu shows a unique pattern of closely packed, comblike teeth in its upper and lower jaws that may have been used for filter feeding, similar to the closely related genus Pterodaustro, and would represent the first member of the broader clade Archaeopterodactyloidea described from the Romualdo Formation.
