Hexagonal Pattern of Dinosaur Skin

A rare mummified dinosaur has been discovered in North Dakota. Notice the beautiful hexagonal pattern of scales. This mummy is thought to be 67 million years old.

From National Geographic:

A newly found "dino mummy" has exquisitely preserved bones, skin, and possibly muscle and internal organs, scientists have announced.

The duck-billed dinosaur, named Dakota, is already changing theories of how the extinct creatures looked and moved—and may contain preserved ancient proteins that could better reveal the dino family tree.
