Lythronax
Order: Saurischia · Suborder: Theropoda · Infraorder: Tyrannosauroidea · Family: Tyrannosauridae (family not firmly confirmed)
Lythronax was a tyrannosaurid predator from the Late Cretaceous of Utah and one of the oldest known members of the group that includes Tyrannosaurus. Despite its early age it already showed the wide skull and forward-facing eyes that gave later tyrannosaurs binocular-like vision useful for hunting. Its name means 'gore king', reflecting its role as a powerful carnivore. Lythronax lived on the ancient landmass of Laramidia and helps scientists understand how the formidable late tyrannosaurs evolved from earlier, often smaller, relatives.
