This is a head portrait of Tyrannosaurus mcraeensis, a proposed earlier cousin of T. rex thought to have hunted in the American Southwest around 72-70 million years ago during the Late Cretaceous. For the most part, T. mcraeensis would have resembled its later and more famous relative, even reaching a similar size, but a shallower lower jaw suggests its bite might not have been quite as powerful as that of T. rex (although, make no mistake, it would have still ranked among the most powerful of any terrestrial carnivore known to science).
