Ancient giant penguin unearthed in Peru

The fossil of a giant penguin that lived 36 million years ago has been discovered in Peru.
...
The team told Science magazine that the animal's feathers were brown and grey, distinct from the black "tuxedo" look of modern penguins.

It was about 1.5m (5ft) tall and nearly twice as heavy as an Emperor Penguin, the largest living species.

The bird, named Inkayacu paracasensis, or Water King, waddled the Earth during the late Eocene period.
