New giant predatory dinosaur discovered in the Cedar Mountain Formation in Utah

November 22 2013

Researchers at The Field Museum, the North Carolina Museum of Natural Sciences (NCMNS), and North Carolina State University (NCSU) have discovered a new, giant predatory dinosaur that walked the Earth approximately 100 million years ago, in the Cedar Mountain Formation in Utah.

The new dinosaur is the first of its kind to be discovered in North America. The study appears in the Nov. 22, 2013 issue of Nature Communications.

The new predator, which was over 30 feet long and weighed more than four tons, was doubtless the top predator in its ecosystem.

“This dinosaur was a colossal predator second only to the great T. rex and perhaps Acrocanthosarus in the North American fossil record,” says Lindsay Zanno, lead author on the paper and Director of Paleontology at NCMNS/NCSU.
