It's what'cha gonna call it.
Zuul first appeared in Dana Barrett's (Sigourney Weaver) refrigerator (yes, refrigerator) back in 1984.
The dinosaur's armoured body allows it to be categorized into the anklylosaurid species from the Late Cretaceous Period and the second part of its name "crurivastator" means "destroyer of shins".
"The skull of the new dinosaur has a short, rounded snout, gnarly forehead, and two sets of horns projecting backward from behind the eyes, just like Zuul", Evans said. The shape of the horns and the ornaments on the skull are what identified Zuul as a species new to science. Typically, complete ankylosaur fossils are hard to find, she said, but in this case, they found not just the creature's body but a complete skull and its entire tail as well - and all of the fossils were said to have been well preserved.
The dinosaur was approximately 20-feet long, the size of a modern day White Rhinoceros. This is the first ankylosaurin skeleton known with a complete skull and tail club, and it is the most complete ankylosaurid ever found in North America.
"I am Dan Aykroyd, aka Ray Stantz, Ghostbuster and you're looking at a closeup of the terror dog from the movie, Ghostbusters", said Aykroyd.
Researchers who discovered it have chosen to name it after the monster, calling it Zuul crurivastator.
"Not only is the skeleton nearly completely intact, but large parts of the bony armour in the skin are still in its natural position", co-author David Evans, curator of vertebrate paleontology at the Royal Ontario Museum, said. Zuul had large spikes at the base of the tail and a grouping of long-peaked spines that ran up the length of the Zuul's tail, with a large club right at the end.
The museum plans to display the entire dinosaur skeleton at an upcoming exhibit, but likely not for a few years as paleontologists are still studying it.
Moreover, Zuul's fossil has rare soft tissue skin impressions and keratinous sheaths on the tail spikes. Also, the tissue was so well preserved that researchers were still able to see spikes still attached to the dinosaur.
