Advances in the biostratigraphy of the Agrio Formation (lower Cretaceous) of the Neuquen Basin, Argentina: Ammonites, palynomorphs, and calcareous nannofossils

Mostrar todas las versiones(2)

Detailed stratigraphic logging and systematic studies on late Valanginian-early Barremian ammonites from the Agrio Formation of the Neuquen Basin of west-central Argentina, have provided a detailed local ammonite zonation. Here we combine the ammonite data with an initial study of calcareous nannofo...
