Dino "mummy" finally on display in Drumheller.

The animal probably died as it lived — defying predators with its heavy armor and size — and after 110 million years, its face remains frozen in a ferocious reptilian glare.

How the animal, a land-dwelling, plant-eating nodosaur, died is not known, but somehow its body ended up at the bottom of an ancient sea. Minerals kept the remains remarkably intact, gradually turning the body into a fossil. And when it was unearthed in 2011, scientists quickly realized that it was the best-preserved specimen of its kind.

“It’s basically a dinosaur mummy — it really is exceptional,” said Don Brinkman, director of preservation and research at the Royal Tyrrell Museum in Drumheller, Alberta. The dinosaur, with fossilized skin and gut contents intact, came from the Millennium Mine six years ago in the oil sands of northern Alberta, once a seabed.
