Meet the Tyrannosaurus Rex's "great-uncle", the King of Gore
A 2.5-tonne relative of Tyrannosaurus Rex with knife-like teeth and eyes made for hunting has been given the title 'King of Gore'.
The 24ft-long carnivore lived 80 million years ago, about a dozen million years earlier than T rex. Its outstanding features were a wide rear skull, short narrow snout and forward-looking eyes.
Scientists named the creature Lythronax argestes, which can be translated as "King of Gore of the South West", a reference to its fierce appearance and the location where it was found.
The predator, which like T rex stood on two legs, inhabited Laramidia, a land mass formed on the western coast of a shallow sea that once split north America in half.
Its remains were discovered in Grand Staircase-Escalante National Monument in Utah, a 1.9 million-acre rugged desert region.
The study of Lythronax is published in the online journal 'Public Library of Science ONE'.
