Prehistoric Penguin Discovered in New Zealand

A new species of penguin from the Eudyptes genus has been discovered in New Zealand!

Hailing from approximately 3 million years ago (the Pliocene), an exceptionally well preserved specimen of penguin fossils has been identified as belonging to Eudyptes. The newly named species, Eudyptes atatu, is evidence that the Eudyptes genus, characteristic for their feathery “crests”, evolved quite recently. The fossil remains were uncovered at the Tangahoe Formation of New Zealand’s North Island. This find implies that the prehistoric region of Zealandia was a Mecca of penguin diversity, from which many species of penguins evolved, diversified and began their spread across the southern hemisphere.

The Tangahoe Formation during the Pliocene would have been a desolate volcanic island landscape containing great plains of gravel, rock bluffs, riverbeds, tussock grasslands, and shores littered with barnacles. A significant amount of what is now the North Island would have been submerged during this time period.
