A new relative of the Tyrannosaurus rex has been unearthed in southern Utah, marking the discovery of the oldest known member of its group of dinosaurs yet. The 80-million-year-old dinosaur looked a lot like T. Rex The discovery is being reported today in PLOS One by researchers led from the Natural History Museum of Utah. With the back of the Lythronax’s skull being on the wider side as well, the researchers note that it actually resembles the T. rex — which lived 10 to 12 million year later — more than any other dinosaur that lived alongside it.
