"New Mexico Discovery: Unearthing T. Rex's Bigger, Older Cousin"

Paleontologists have discovered a newly identified subspecies of tyrannosaur, Tyrannosaurus mcraeensis, in New Mexico, which is believed to be the closest known relative of the T.Rex. This finding reshapes scientists' understanding of how T. Rex might have first arrived in North America, suggesting that tyrannosaurs lived in the southern United States at least 72 million years ago. The newly discovered dinosaur, roughly the size of a T. rex, predates it by about five to seven million years, indicating the presence of larger, more advanced species in the southern United States. The findings, based on a partial skull collected years ago, have been published in the Scientific Reports journal.
