Biology:Laventan
From HandWiki
The Laventan (Spanish: Laventense) age is a period of geologic time (13.8 to 11.8 Ma) within the Miocene epoch of the Neogene, used more specifically with South American Land Mammal Ages. It follows the Colloncuran and precedes the Mayoan age.[1][2]
Etymology
The age is named after the Miocene Lagerstätte La Venta, where a rich biodiversity from the Middle Miocene has been recovered from the Honda Group.[2]
