Some 90 million years ago, two-footed meat-eating dinosaurs began undergoing big changes. They were adapting to conditions in what is now the western United States. Best known among this line would be the fearsome Tyrannosaurus rex. But some of its ancestors also would have cut a mean swath through the countryside. Consider Lythronax argestes (LYE-thro-nax Ar-GESS-tees). A newfound addition to the family, it’s the earliest. And its Greek name says it all: Gore King of the Southwest.
