This dino didn’t just leave bones behind—its face, skin, and even stomach contents were preserved!
In an astonishing paleontological breakthrough, scientists uncovered one of the most complete dinosaur fossils ever found: a 110-million-year-old ankylosaur with its face, skin, armor, and even stomach contents nearly intact.
The fossil, discovered in 2011 and painstakingly excavated over six years by technician Mark Mitchell at Canada’s Royal Tyrrell Museum, is so well-preserved that researchers could see the texture of its skin and the arrangement of its armor spikes. In honor of his work, the new species was named Borealopelta markmitchelli.
The fossil’s remarkable preservation has allowed scientists to publish groundbreaking studies on dinosaur behavior, appearance, and even diet. Researchers found that the creature likely used countershading camouflage—dark on top, light underneath—a surprising trait for such a heavily armored dinosaur. Other insights suggest that its spiky armor may have been more about attracting mates than fighting predators. And with its last meal still fossilized inside, Borealopelta gives a rare glimpse into what plant life these ancient creatures dined on. It's a discovery that not only shows the face of a dinosaur—but reveals a whole new side of their world.
