A Dinosaur So Well Preserved It Looks Like a Statue [View all]

In March 2011, a construction worker named Shawn Funk visited an impressive dinosaur collection at the Royal Tyrrell Museum in Alberta. As he walked through halls full of ancient bones, he had no idea that a week later, he’d add to their ranks by finding one of the most spectacular dinosaur fossils of all time. It’s an animal so well preserved that its skeleton can’t be seen for the skin and soft tissues that still cover it.

When we look at dinosaurs in museums, it takes imagination to plaster flesh and skin on top of the bones. But for the dinosaur that Funk unearthed—a 110-million-year-old creature named Borealopelta—imagination isn’t necessary. It looks like a sculpture. And based on pigments that still lurk within the skin, scientists think they know what colors the animal had. “If someone wants to come face to face with a dinosaur, and see what it actually looked like, this is the one for that,” says Caleb Brown from the Royal Tyrrell Museum, who has studied the animal.

Borealopelta was one of the ankylosaurs—a group of heavy-set, low-slung, tank-like dinosaurs. It lacked the shin-thwacking tail clubs that some of its relatives wielded, but its back was covered in heavy, armored scales, and a pair of 20-inch-long spikes jutted from its shoulders. It weighed 1.5 tons and was 20 feet from foot to tail. And it probably couldn’t swim very well.

Somehow, this particular individual ended up at sea. Perhaps it got careless on a shoreline. Perhaps it drowned in a flood and was washed out to sea. Either way, gases started building up in its body, causing it to float belly-up. As those gases released, the dead dinosaur sank, and hit the ocean floor hard enough to leave a small crater. Before sharks had a chance to nibble it, or worms had a chance to bury into its bones, it was quickly smothered by fine sediment and sealed off from the outside world. There it remained for millions of years, until March 11, 2011, when an excavator bit into it.
