Meet T. rex’s oldest relative: the ‘Gore King’

A new relative of the Tyrannosaurus rex has been unearthed in southern Utah, marking the discovery of the oldest known member of its group of dinosaurs yet. The newly discovered dinosaur measured about 24 feet long, weighed around 2.5 metric tons, and had a large head filled with sharp teeth. To evoke just what a powerful predator it was, researchers have given it a fittingly grand name: Lythronax argestes, which translates to gore king of the Southwest.
