The creature belongs to a newly discovered species within the nodosaur family. In August, it was given a name: Borealopelta markmitchelli.

Zuul, shown here, had a tail like a sledgehammer, which it may have used as a weapon.


The nodosaur was about 18 feet long and weighed nearly 3,000 pounds. It had bony, bumpy plates of armor. Scientists think that millions of years ago, the pit where the fossil was found was under the sea. Minerals in the water preserved the remains.

“We’ve got all the armor,” Henderson says. “Even better, we’ve got the scales, which we can see between the rows of armor and on top of the armor. No one’s ever seen that before.”

A Movie Monster

Also in May, researchers from the Royal Ontario Museum (ROM), in Toronto, Canada, published a report about a new ankylosaur species. Its fossilized skeleton was found in Montana. The creature lived around 75 million years ago, was about 20 feet long, and weighed nearly 5,500 pounds.

Scientists named that dinosaur Zuul crurivastator after Zuul, a monster in the 1984 movie Ghostbusters. Both creatures have a short, rounded snout and horns above the eyes.

In a statement, the ROM called Zuul “one of the most complete and best-preserved ankylosaurs ever discovered.”
