Ebyewuunyisa

Lythronax is the oldest known tyrannosaurid dinosaur, living about 80 million years ago.2

Its skull was wide at the back, which gave it forward-facing eyes like T. rex, but it lived millions of years earlier.1 2

The only known specimen was discovered in 2009 in the Grand Staircase-Escalante National Monument in Utah.1

Lythronax lived on a landmass called Laramidia, which was isolated by a huge inland sea.1 2

Its name means 'gore king', referring to its bloody lifestyle as a predator.1 2

Lythronax had 11 teeth in its upper jaw, fewer than some later tyrannosaurs.2
