Triceratops Trio Found in Wyoming: Report

Triceratops trio found: Scientists say they have found three Triceratops fossils in Wyoming, including one of the most complete skeletons of the dinosaur to date.

“The largest, more mature individual appears to be the most complete,” paleontologist Peter Larson with the Black Hills Institute of Geological Research told CNN.. “One is just a bit smaller, and there’s another one that by live weight is probably only half the size.”

Triceratops dinosaurs lived around 68 million to 65.5 million years ago, were herbivores, and had three distinctive horns on its head.

However, the most complete Triceratops skeleton is only around 76 finished and is on display in Houston. “There’s only three other skeletons that will match the completeness of one of the specimens we’re excavating right now,” Larson said.

Paleontologists are digging near Newcastle, located around 200 miles south of Cheyenne.

Larson said that the three might be a male and female looking after their offspring. But it could also be two females looking after a young dinosaur.

“The dig indicates that there was some sort of parental pair and nowhere in the literature has that ever been noted before, and that’s unprecedented,” Larson told the Jackson Bolstad Journal.
