Think the Tyrannosaurus rex was tough? Meet its great-uncle, whose name means "king of gore."
Paleontologists unveiled a new species of tyrannosaur, Lythronax argestes, on Wednesday at the Natural History Museum of Utah.
The 80-million-year-old sharp-toothed skeleton was unearthed in Grand Staircase-Escalante National Monument. The 24-foot-long dinosaur walked on two legs like the T. rex in a swampy, subtropical coastal setting. It weighed some 2.5 tons and had a large head with a relatively narrow, short snout that widened at the back of the skull, giving its forward-facing eyes a great view for spotting prey.
A team of scientists from the Natural History Museum and the Grand Staircase National Monument discovered parts of the skull, hips, leg and tail during an excavation in March and May of 2009.
