US construction workers find 66m-year-old triceratops skeleton

AFP . Washington | Update:

This handout photograph obtained August 31, 2017 courtesy of the City of Thornton in the western American state of Colorado shows the dinosaur skeleton and skull of a triceratops, which scientists from the Denver Museum of Nature & Science (DMNS) say has been lying in the location for 66 million years. AFPConstruction crews breaking ground on a new fire and police station north of Denver, Colorado have unearthed a 66-million-year-old triceratops skeleton, sparking a flurry of scientific interest in this iconic herbivore.

Diggers working on a site in Thornton-population 137,000 -- encountered an immovable object on August 25.

One of the workers thought it might be a fossil, so they called the Denver Museum of Nature and Science.

Curator Joseph Sertich arrived at the scene and identified the bones as belonging to a triceratops.

“This is a pretty small triceratops,” Sertich said in a Facebook Live broadcast from the work site on Wednesday.

This fossil is about half the size of triceratops unearthed in Montana and North and South Dakota.

“We don’t really know why,” Sertich said.

“Even though we have hundreds of triceratops from the American West, we only have three good skulls. And this might be one of the best skeletons to tell us why Denver triceratops are smaller than all of their cousins everywhere else.”

Paleontologists have found a horn, a shoulder blade, parts of the frill, tailbone and other skeletal remains.

Experts will be digging for the next couple of weeks with brushes and small tools to uncover as many of the bones as possible.

“All these bones are going to go back to the Denver Museum, we are going to put them right up in our window,” Sertich said.

Visitors to the museum could see them as early as this weekend, he said.

Another triceratops was found in 2003 about two miles (three kilometers) away.

“It was found in exactly the same way. A bulldozer operator plowed through it, took half of it away but the other half was perfect and we were able to salvage that and take it back to the museum,” Sertich said.
