Tuxedoless Penguins

Recently, scientists discovered a gigantic penguin from millions of years ago. According to the NPR piece, this penguin is from the Eocene period and did not have the traditional penguin tuxedo markings that we know today. Scientists believe from little modules on the feathers that they can determine the color patterns on some parts of the penguin including the flipper.

"These giant penguins have quite elongate, prominent beaks. And, of course, their size is striking. Would you immediately recognize something that's twice the size of a living penguin and had a different beak morphology and was differently colored as a giant penguin on first seeing it? I think - I'm not sure we would've. " (NPR)

The story is pretty cool.
