Inkayacu paracasensis is named after the Quechua words for “water king” and the Paracas National Park where it was discovered by Julia Clarke from the University of Texas. Clarke’s team are no strangers to giant fossil penguins. In 2007, they unveiled two extinct species: Perudyptes, about the size of the modern king penguin; and Icadyptes, which was larger than any living species and had an unusually long, spear-like beak. Like Icadyptes, Inkayacu also swam off the coast of ancient Peru, had a long beak, and was one of the largest penguins in history. It weighed around twice as much as the heaviest of today’s penguins – the emperor.

In many ways, Inkayacu is no more significant a find that Icadyptes was three years ago. It is neither the oldest nor the largest penguin fossil, it doesn’t hail from a new part of the world, and it provides few clues about the group’s evolution. However, it does have one stand-out feature that probably secured its unveiling in the pages of Science – its feathers.
