Mustersan

The Mustersan age is a period of geologic time (48.0–42.0 Ma) within the Eocene epoch of the Paleogene, used more specifically within the South American land mammal age (SALMA) classification. It follows the Casamayoran and precedes the Divisaderan age.[1][2]

Etymology

This age is named after Lake Musters in the Golfo San Jorge Basin.
