Merced college student, 23, unearths a 65-million-year-old triceratop­s skull

Harrison Duran, a biology student at UC Merced, had just been rejected from a summer internship when he received an invitation from a professor to go fossil hunting in a remote area of North Dakota.

Duran, 23, accepted the offer. Just four days into the two-week trip, he was helping uncover parts of a skull belonging to a tricer- atops, most likely about 65 million years old.

In an interview Friday, Duran sounded a note of regret that he did not land the internship, at the La Brea Tar Pits and Museum in Los Angeles. Still, he said, he was happy with how things ultimately worked out.

“I think I found a more significan­t treasure in the Badlands,” he said.

On June 4, the pair spied what they first thought was petrified wood but later turned out to be a bone fragment — specifical­ly, a roughly 3-foot horn that would have been attached to the dinosaur’s left brow. The discovery was made in the Hell Creek Formation, a series of rock formations that cover parts of Montana and the Dakotas dating to the end of the Cretaceous Period, about 66 million years ago.

According to Michael Kjelland, the professor who invited Duran on the dig, the area has produced bones from three triceratop­s, an unusually high concentrat­ion.

Kjelland, who teaches biology at Mayville State University in North Dakota, said it was too early to glean the significan­ce of the bones, which might not be part of a complete skeleton. He has seen several triceratop­s skulls in the course of his studies, he said, including one belonging to an almost fully intact fossil called Gundy that was discovered in the region in 1992.

Duran said he had a childhood passion for dinosaurs that simply never dwindled.

“I’ve always found it fascinatin­g that there are lost worlds to be discovered,” he said, adding that learning about the period before humans arrived was “very important for understand­ing life on Earth.”

Duran met Kjelland a few years ago at a biotechnol­ogy conference, and the two have since teamed on several projects, including starting a nonprofit called Fossil Excavators.

One of the organizati­on’s objectives, Kjelland said, is to provide opportunit­ies for students like Duran.

“It’s not just digging fossils,” he said. “It’s being out in nature” and learning what the past can teach us about how to prevent extinction and the worst effects of global warming.

Before the dig, Kjelland warned Duran that they might have to eat rattlesnak­es and live off the land to survive in the Badlands, a region known for its extreme temperatur­es, scorpions and swarming insects.

“You have to have patience, too, because these are multipiece, 3D jigsaw puzzles, and it’s quite a process to get them excavated and out,” he said. Duran was undeterred. It took about 10 days to extract the fragile skull and “engineerin­g that rivaled SpaceX,” he joked. They used pickaxes to dig out the ground around it and elongated screwdrive­rs to pry the dirt and the mud apart from the bones.

To stabilize the bones for transporta­tion, they used a glue specifical­ly formulated to seep into the crevices and an accelerati­ng agent to harden it. Once the skull, which, excluding its fan-shape frill, is about 5 feet long, was out of the ground, they wrapped it in strips of foil and burlap dipped it in plaster to make a cast. They built a makeshift crate out of twoby-fours and taped memory foam to a protruding cheekbone to reduce vibrations in transit. They used an excavator to hoist the skull, which they estimated weighed 750 to 1,000 pounds, onto a local cattle rancher’s truck.

Duran and the fossil excavators made a video of the expedition.

They named the skull Alice, after the landowner who had allowed them to dig on her property.

Alice’s skull is currently resting in a plaster jacket in Kjelland’s lab on the outskirts of Valley City, North Dakota.

“I’m not totally sure yet where she’s going,” Kjelland said Friday. “I want it to be somewhere where a lot of folks can visit her and see her and maybe do some research on her.”

For his part, Duran said he hoped to take some of the molds back to the Merced campus.

This summer, he is taking a course in organic chemistry in order to graduate in the fall. He is not sure yet what career he wants to pursue, but it will most likely be in biotechnol­ogy or paleontolo­gy, he said.

And he plans to keep digging in North Dakota.

“There are plenty of secrets that remain in the Badlands,” he said.
