In 2016, students from the Natural History Museum at Kansas University found a relatively small dinosaur pelvis in the Hell Creek formation in Montana. It was the end of their dig season and they didn’t have the time to unearth the rest of the remains. But the fossil was worth the wait; when they returned last summer, they found part of a jaw, teeth and skull segment of what appears to be a 66.5-million-year-old juvenile T. rex, reports Laura Geggel at LiveScience.
