Eocene Antarctica: a window into the earliest history of modern whales.
The Eocene–Oligocene Southern Ocean is thought to have played a major role in cetacean evolution. Yet, fossils from its heart – Antarctica – are rare, and come almost exclusively from the Eocene La Meseta and Submeseta formations of Marambio (Seymour) Island. Here, we provide a summary and update of...

The Eocene–Oligocene Southern Ocean is thought to have played a major role in cetacean evolution.

To date, Eocene specimens from Antarctica include basilosaurids, a group of archaic stem cetaceans that had already fully adapted to life in water; and the archaic toothed mysticete Llanocetus , the second oldest crown cetacean on record (ca. 34 Ma).
