| Abstract: | The clade Tapejaridae is composed by pterosaurs commonly found in fossiliferous deposits in northeastern Brazil. It is constituted by two less inclusive clades: the smaller-bodied Tapejarinae and the larger Thalassodrominae. Here we describe the specimen MN 6566-V, from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. The specimen is overall well preserved tridimensionally, and consists of three posterior cervical vertebrae, incomplete right and left scapulocoracoids, and the proximal portion of a right humerus. Comparisons to specimens described in the literature enable its identification as a thalassodromine, whose postcranial material is still poorly known despite the large amount of pterosaurs known from this unit. |
