Ancient reptiles flew in flocks

During the Late Cretaceous period 100 million to 66 million years ago, 47 adult and juvenile pterosaurs died in a desert lake in southern Brazil possibly desiccated by drought. Now, paleontologists from Brazil’s Federal University of Rio de Janeiro say that the skeletons of Caiuajara dobruskii, a newly identified species of pterosaur, provide the strongest evidence that the ancient reptiles traveled in flocks, National Geographic reports. The new species boasts bony ridges between its eyes and sail-like crests unlike any other pterosaurs, which the researchers describe online in PLOS ONE.
