The Itaboraian (Portuguese: Itaboraiense) age is a period within the Early Eocene geologic time (53.0–50.0 Ma) epoch of the Paleogene, used more specifically with South American land mammal ages (SALMA). It follows the Riochican and precedes the Casamayoran age.[1]

Etymology

[edit]

This age is named after the Itaboraí Formation in the Itaboraí Basin in Itaboraí, a Greater Rio municipality in the state of Rio de Janeiro in Brazil not very far away from Niterói.
