The first pterosaur tracks from Gondwana

Abstract Pterosaur tracks from the Candeleros Member of the Rio Limay Formation (Albian–Cenomanian) at Lake Ezequiel Ramos Mexia, Neuquen Province, Argentina, are the first pterosaurian tracks reported from South America and from the Southern Hemisphere. Although the individual footprints are not well preserved, some trackway segments and manus-pes sets are preserved, suggesting that the tracks can be assigned to cf. Pteraichnus ichnosp. indet. The palaeoenvironmental setting of the track beds is a lake shoreline, where dinosaur tracks also occur. The discovery is consistent with reports of well known pterosaur-bearing Lagerstatten in the Lower Cretaceous of South America.
