A new species of pterosaur, Coloborhynchus spielbergi sp. nov. (Pterodactyloidea), from the Romualdo ember (Albian) of the Santana Formation is described. The type consists of the skull, mandible and many of the post-cranial bones. The specunen displays a high degree of co-ossification indicating that the animal was an adult and likely quite old when it died. The wingspan is reconstructed at nearly 6 m. Among the characteristic features are a large anteriorly positioned premaxillary sagittal crest and a smaller, also anteriorly positioned dentary sagittal crest, a flat anterior aspect of the skull from which two teeth project and a ventrally fused pelvis. Comments on Brazilian pterosaurs are made in cormection with the classificiation of the Leiden specimen.
