Marplatan

The Marplatan age ('Uquian') is a period of geologic time in both the Pliocene and Pleistocene epochs, used specifically within the South American Land Mammal Ages.

Chronology
The Marplatan age follows the Chapadmalalan and precedes the Ensenadan age. The source localities for all three subages (Barranca de los Lobos Formation, Vorohué Formation, San Andrés Formation) come from near Mar del Plata, Buenos Aires Province, Argentina. == Barrancalobian ==
Barrancalobian
The Barrancalobian is the first subage of the Marplatan, and is characterized by the Platygonus scagliai biozone. A possible cosmic impact occurred at the start of the Marplatan (3.3Ma) in Argentina. == Vorohuen ==
Vorohuen
The Vorohuen subage contains the Akodon (Akodon) lorenzinii biozone. == Sanandresian ==
Sanandresian
The Sanandresian subage concludes the Marplatan, and coincides with the Ctenomys chapalmalensis (Paractenomys chapadmalensis) biozone. == References ==
