ROM scientists name new dinosaur species after Ghostbusters villain – Technology & Science

Scientists from the Royal Ontario Museum have recently discovered the fossil of a 75-million-year-old species of armoured dinosaur, or ankylosaur, which was unusually well-preserved — and oddly familiar to movie buffs.

Meet Zuul crurivastator — destroyer of shins — whose discovery is being discussed in the Royal Society Open Science journal.

The name was inspired by the Ghostbusters villain Zuul, says Victoria Arbour, paleontologist and postdoctoral fellow at the ROM and University of Toronto.

“Me and my co-author David Evans were batting around ideas for what to name it, and I just half-jokingly said, ‘It looks like Zuul from Ghostbusters,'” she said. “Once we put that out there we couldn’t not name it that.”

But there’s much more to this discovery than a catchy name.

The plant-eating species has a short, rounded snout and prominent horns behind the eyes. A large knob of bone at the end of its stiffened tail could have been used to strike predators in the legs (hence the name destroyer of shins) or for battling others for territory or mates, the scientists said.

The tail is three metres long and covered in rows of large bony spikes, adding to its menace.

“I wanted to name something an ankle breaker because of these tail clubs,” Arbour said. “But I wanted a specimen with a nicely preserved tail, and they don’t get better than this particular specimen.”

Finding a full dinosaur skeleton is a rare feat, she said, and is especially uncommon for this group of dinosaur.

“They were slightly more rare animals in their ecosystems compared to other dinosaurs we know from the same areas, such as the duck-billed dinosaur.”

Nearly complete skeleton

It’s also rare to find an ankylosaur skeleton well-preserved, because the armour is part of the skin, Arbour said, which would tend to get washed away from the skeleton.

With this discovery, scientists have the full skull, tail, body, armour and even some preserved soft tissue, she said.

“This is a really useful specimen, we can visualize what it looked like while it was alive, and it will also help with isolated bones [of other animals] and give us an idea of what we’re looking at,” Arbour said.

Paleontologists often find bone fragments from the armour of other ankylosaurs, she said, but without the full picture it’s hard to determine what the bones are. This specimen will help in identification.

“It’s kind of like a Rosetta stone in some ways.”

The fossil was found in the Judith River Formation in Montana, just 25 kilometres south of the Alberta border, Arbour said. It was uncovered when a crew of private…
