On the Pterosaur Remains from the Ŕio Belgrano Formation (Barremian), Patagonian Andes of Argentina
Pterosaur remains from the Río Belgrano Formation, Santa Cruz Province, Argentina, were found close to the Estancia Río Roble, along with several ammonoids that indicate a Barremian age for those strata. The specimens (MACN-SC 3617) consist of one ulna and one element tentatively identified as a por...
