Stratigraphy
Formation:Puerto Belgrano
Stratigraphic resolution:group of beds
Stratigraphy comments: The stratotype of this zone overlies the stratotype of the Zone of Trigodon gaudryi (from the unconformity separating units I and II of Fidalgo and Tonni, 1982) and ranges to the base of the postchapadmalalan (Kraglievich, 1946) Puerto Belgrano Formation of Zavala (1993;

The Zone of Neocavia depressidens should be considered the lower part of the Chapadmalalan.
