A previously undiscovered species, Caiuajara dobruskii was a flying reptile with a large bony crest on its head and a wingspan measuring up to 8ft. The discovery is particularly rare and valuable because it is the first time that such an extensive "bone bed" has been found for a pterosaur species."The presence of three main levels of accumulation in a section of less than one metre suggests that this region was home to pterosaur populations for an extended period of time," said study leader Dr Alexander Kellner of Rio de Janeiro's Federal University.

"The causes of death remain unknown, although similarities with dinosaur drought-related mortality are striking. However, it is also possible that desert storms could have been responsible for the occasional demise of these pterosaurs."
