Earth:Colhuehuapian

Short description: Period of geologic time (21.0–17.5 Ma)

The Colhuehuapian age is a period of geologic time (21.0–17.5 Ma) within the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Deseadan and precedes the Santacrucian age.

Etymology

The age is named after the Colhué Huapí Member of the Sarmiento Formation in the Golfo San Jorge Basin, Patagonia, Argentina .
