Friasian

The Friasian age is a period of geologic time (16.3–15.5 Ma) within the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification of South America. It follows the Santacrucian and precedes the Colloncuran age.^[1]

Etymology[]

The age is named after the Río Frías Formation in the Aysén Basin, Patagonia, Chile.
