Join paleontologist Jack Horner on a journey into the arid badlands of Montana where more T. rex skeletons have been uncovered than any other place on earth. Follow Horner – who found five T. rex dinosaurs here in a single summer – as he scrutinizes the T. rex's arms, large olfactory lobes, tiny eye sockets and unique teeth, to gain insight into whether T. rex was a ferocious predator or an opportunistic scavenger. For example, Horner surmises that the T. rex's stumpy arms wouldn't allow T. rex to scoop up prey, indicating he may have come along after the kill.Among Jack Horner's finds is the oldest T. rex ever found. At 68 million years, it's 3 million years older than any other specimen challenging the beliefs of when T. rex roamed the Earth. Also, see a 90% complete never before seen juvenile tyrannosaur called Daspletasaurus – an earlier large meat-eating cousin of T. rex. Visit dig sites, labs and museums, and witness brilliant computer animation that visualizes how these creatures lived and died. Plus, see new evidence that could allow scientists to reach ever further back in time.
