David M. Martill & Eberhard Frey, A new pterosaur Lagerstätte in N. E. Brazil (Crato Formation; Aptian, Lower Cretaceous) : preliminary observations. Oryctos 1, 79-85.
Although pterosaurs are rare in the Nova Olinda Member of the Crato Formation (Aptian, Lower Cretaceous, Araripe Basin, N.E. Brazil), their remains have been recovered in increasing numbers over the last five years from the numerous stone pits between Nova Olinda and Santana do Cariri. Several distinct forms are known including tapejarids, a possible ornithocheirid and a possible azdharchid. Some specimens exhibit soft tissue preservation and structures previously unknown in related pterosaurs from other sites have been revealed. Preservational styles are variable in that some specimens are articulated, but examples also occur as partially articulated remains; associated, but disarticulated elements and as isolated bones.
