Chasicoan

The Chasicoan (Chasiquense or 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.

Etymology
The Chasicoan is named after the Arroyo Chasicó Formation of the Colorado Basin in northeastern Argentina.
