In a discovery almost 10 years in the making, paleontologists with the Royal Tyrrell Museum have now unveiled a new, never before seen dinosaur.

First found by a southeastern Alberta resident back in 2005, Regaliceratops peterhewsi, has been given the nickname ‘Hellboy’ in regard to the hellish conditions surrounding excavation and the hardness of the rock surrounding the find.

David Eggen, Alberta’s Minister of Culture and Tourism says the find is significant because it expands our knowledge and understanding of horned dinosaurs.

Regaliceratops grew to roughly the size of a large SUV, weighing about 1.5 tonnes. It had a large nose horn with smaller secondary horns above its eyes.

The most distinguishable characteristic was its large, jagged-edge, shield-like frill, the largest ever recorded among dinosaurs of its type.

Peter Hews, a geologist from Calgary, first spotted the fossil in 2005 when he spotted a piece of bone protruding from a cliff overlooking the Oldman River.

Royal Tyrrell Museum scientists Dr. Caleb Brown and Dr. Donald Henderson completed the research on the specimen, considered to be one of the most impressive finds since Triceratops.

“While the palaeontological community is constantly finding new dinosaurs, they are often represented by only small fragments of a skeleton, which can make it hard to imagine what they looked like. With “Hellboy,” there is a huge, nearly complete skull of a very distinct new animal, and visitors to the Museum will be the first to see it on display,” said Dr. Brown in a release.

It wasn't easy to get the dinosaur out of the ground either. The find was deep inside a steep riverside cliff over a bull trout  spawning ground.

Bull trout are a protected species in Alberta, so Brown and his team needed to take extra care not to knock dirt or sediment into the water.

To make matters worse, the fossil, once extracted, was encased in solid rock that needed about a year and a half of work to uncover.

The skull will be on display as part of the Royal Tyrrell’s Fossils in Focus exhibition.

The new area will also show off some of the museums most significant finds in its history.

It opens on June 4.
