Cretaceous palynomorphs from the Springhill Formation at Estancia El Salitral, southern Patagonia

The Springhill Formation at Estancia El Salitral, Santa Cruz province, yields a distinctive palynological assemblage of miospores and subordinate dinoflagellates. The occurrence of Muderongia staurota Sarjeant emend. Monteil together with several species such as Circulodinium distinctum Deflandre an...
