From Ed Yong: All modern penguins wear a suit of black feathers,
but prehistoric members of the group didn’t go for the dinner
jacket look. A newly discovered penguin, known as Inkayacu, was
dressed in grey and reddish-brown hues. 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. Read about Inkayacu‘s magnificently preserved fossil
feathers and what they tell us about this prehistoric bird at
Not Exactly Rocket Science. Ed also has the artists’ renderings
of what this powerful penguin may have looked like. 80beats:
