WOODLAND PARK, Colo. -

A brand new species of dinosaur was unveiled in southern Colorado Wednesday.

It is the first of its kind discovered anywhere in the world.

Paleontologists at Triebold Paleontology, Inc. say it's most likely some type of Ceratopsian dinosaur because it has horns on its head.

The Rocky Mountain Dinosaur Resource Center is calling it "Ava" while paleontologists decide what to name this new species.

"This one is different in a lot of ways and it adds to the body of knowledge humans have about the history of the world," said Mike Triebold, owner of Triebold Paleontology.

Paleontologists from Woodland Park found Ava three years ago in Montana.

At first, they thought it was an Avaceratops, which is a dinosaur with horns on its head.

But they quickly realized there were many key differences.

"It doesn't have a horn on its nose and the shape of the head and body are different," Anthony Maltese said. "The shape of the horns and they way they face also make it unique."

Maltese is a curator at the Dinosaur Resource Center who helped uncover Ava.

"This is a huge deal for us because we haven't found a new species in several years," Maltese said.

Paleontologists said finding a new species is rare.

In 24 years of uncovering dinosaurs, the Resource Center has been home to 20 dinosaurs, but only three or four new species.

"It's really cool when you're the first person who figures out that this is the way it's uspposed to look and no one has seen this ever!" Maltese said.

The magnitude of the find wasn't lost on 15-year-old Lauren Keller.  She came to the museum specifically to see the new dinosaur, hoping one day to find her own as a paleontologist.

"It's a once in a lifetime opportunity and I'm blessed I got to see it," Keller said.  "It's not something many people can say they did and it's really exciting."

Ava took three years and hundreds of thousands of dollars to excavate and recreate.

But Maltese said that's actually a relatively short process compared to others.

"We're really lucky because it was a well preserved specimen.  We found 85% of the bones, which isn't a usual find," he said.

The rest were made with the help of a 3D printer.

"It takes a mirror image and puts it in the computer and we can print it out and use it to make molds without any human error," Maltese said.

Maltese and the rest of the group who worked on Ava said the time and effort was worth it.

"This dinosaur has been buried in the ground for 72 million years and for the first time, it is all put back together like how it would have looked if it had been alive," Triebold said. "And humans are getting to see that."

Ava was a four-year-old herbivore.

Ava is on display at the Rocky Mountain Dinosaur Resource Center until Oct. 9.
