"Newly Identified Tyrannosaurus Species Unearthed in New Mexico"

A newly discovered giant dinosaur species, Tyrannosaurus mcraeensis, may be the closest known relative of Tyrannosaurus rex, and could represent the moment the genus experimented with a huge body. The distinction of this new species was confirmed through examinations of its fossilized skull, which was found in New Mexico and lived around five million years before T. rex. The discovery suggests that T. rex may have evolved in Western North America, and the findings also shed light on the evolution of giant body sizes in tyrannosaurids.
