A new penguin cranium from Antarctica and its implications for body size diversity during the Eocene

Although penguins have a very abundant fossil record in Antarctica, very few cranial elements have been found so far, and in all the cases the specimens are incomplete. We describe a new cranium of a medium-sized penguin from the late Eocene Submeseta Formation in Marambio/ Seymour Island, Antarctic...
