THORNTON TRICERATOPS LIKELY MOST COMPLETE CRETACEOUS-PERIOD SKELETON FOUND IN DENVER METRO AREA

DENVER―Sept. 1―The Denver Museum of Nature & Science has uncovered a total of 12 Triceratops
bones at the construction site for the City of Thornton’s Public Safety Facility.

“Based on what we’ve uncovered up to this point, this find is likely the most complete Cretaceousperiod
skeleton ever found in this region,” said Joe Sertich, Denver Museum of Nature & Science curator
of dinosaurs. “This is what we as curators dream about—getting a call about a possible fossil and
confirming it’s not just a dinosaur fossil, but a record-breaking one!”

In addition to exposing several fossils, a rib bone weighing about 40 pounds was the first to be
completely extracted. Today, it will make its way to the Museum in a white plaster jacket.

The excavation team—made of volunteers from the Museum, the Colorado Office of Archaeology,
Saunders Construction, Inc., and the City of Thornton—will continue to excavate the Triceratops
focusing on the skull and frill bones.

On Monday, Aug. 28, the City of Thornton and the Museum confirmed that the horn and shoulder blade
of a Triceratops fossil was partially unearthed at the construction site of Thornton’s newest city building.
While the excavation team works, construction on Thornton’s new Public Safety Facility continues.
