Santacrucian
South American land mammal age (SALMA)
The Santacrucian age is a period of geologic time (17.5 – 16.3 Ma) within the Early Miocene epoch of the Neogene, used more specifically with SALMA classification in South America. It follows the Colhuehuapian and precedes the Friasian age.[1]
Etymology
The age is named after the Santa Cruz Formation in the Austral/Magallanes Basin of southern Patagonia, Argentina and Chile.
