Scientists at the Paracas National Reserve in Peru have discovered the fossil of a penguin that was five feet tall and weighed nearly twice as much as the Emperor penguin, the largest living penguin species.

The Inkayacu paracasenis, or Water King, sported a long black beak and brown and gray features — unique compared to the "tuxedo" appearance of modern penguins. The Water King lived in the Paracas region, on the Pacific coast south of Lima, 36 million years ago during the Eocene period.

The fossil, dubbed "Pedro" by scientists, is important in answering key questions about penguin evolution.
