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.
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 ==
The Sanandresian subage concludes the Marplatan, and coincides with the Ctenomys chapalmalensis (Paractenomys chapadmalensis) biozone. == References ==
