Mayoan

The Mayoan (Spanish: Mayoense) age is a period of geologic time from 11.8 to 10 Ma, within the Middle to Late Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Laventan and precedes the Chasicoan age.^[1]

Etymology

The age is named after the Río Mayo Formation in the Golfo San Jorge Basin of Patagonia, Argentina.
