Huayquerian


The Huayquerian age is a period of geologic time within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification. It follows the Chasicoan and precedes the Montehermosan age.

Etymology

The age is named after the Huayquerías Formation in the western Cuyo Basin of northwestern Argentina that was later dated to the Montehermosan. The most complete Huayquerian fauna is found in the Cerro Azul Formation, in Buenos Aires Province also referred to as Epecuén Formation.
