NEW YORK (AP) -- Scientists have discovered a killer dinosaur that roamed in what is now Utah some 100 million years ago. Experts say the discovery provides insight into the top predators in North America before T. rex showed up.

The two-legged beast was more than 30 feet long and weighed more than 4 tons. It helps fill a gap in the fossil record of North American big predators before the arrival of the group including T. rex. It wasn't related to that famous beast.

Researchers from the Field Museum in Chicago and the North Carolina Museum of Natural Sciences in Raleigh announced the finding Friday in the journal Nature Communications. They named the beast "Siats meekerorum," after a legend of Utah's Ute tribe and a family that has donated to the Field Museum.
