New dinosaur species named after 'Ghostbusters' monster Researchers named the dinosaur "Zuul crurivastator" for its skull similarities.

 -- A newly unveiled dinosaur species was named for its striking resemblance to the supernatural monster Zuul from the 1984 hit film "Ghostbusters." Who you gonna call? Dan Aykroyd, of course.

Aykroyd, one of the film's stars, stopped by the Royal Ontario Museum to meet the beast face-to-face.

Researchers debuted Zuul crurivastator, an armored dinosaur described as one of the most complete ankylosaur fossilized skeletal remains ever, unearthed from the Judith River Formation in Montana.

The scientists said they first uncovered the perfectly preserved 6.7-foot-long spiked tail of the estimated 20-foot-long prehistoric beast, which they believe helped it defend itself from predators. The massive club-like tail inspired its name crurivastator, which literally translates to "Destroyer of Shins."

But it was the dinosaur's broad rounded snout and spiky headed skeleton that sparked its comparison with Zuul, the demonic character from the original "Ghostbusters."

The nearly pristine dinosaur was preserved in a body of water and believed to have roamed the Earth approximately 75 million years ago.
