Chasicoan

The Chasicoan (Spanish: Chasiquense or Spanish: Chasicoense) age is a period of geologic time from 10–9 Ma within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Mayoan and precedes the Huayquerian age.

Isotopic analysis of the fauna at Arroyo Chasicó, the type locality of the Chasicoan Stage/Age, indicates a paleoenvironment characterized by woodland and wooded C3 grassland, with some taxa showing mixed C3–C4 diets.
