T. Rex Was Harder to Kill Than You Think... Here Is Why

T. Rex survived injuries that should have killed almost any other animal. Broken ribs. Punctured skulls. Severe infections. A fractured neck that healed while the animal was still alive. Fossils from famous Tyrannosaurus rex specimens like Sue, Stan, and Jane reveal something disturbing: T. rex was not hard to hurt — it was incredibly hard to put down. In this documentary, we examine the fossil evidence behind some of the worst injuries ever found on T. rex skeletons and ask how these animals survived damage from predators carrying the same bone-crushing weapons they did. Sue, one of the most complete T. rex skeletons ever discovered, lived with healed fractures, disease, arthritis, and mysterious holes in the jaw that scientists are still debating today. Stan survived puncture wounds to the skull and a fractured neck vertebra that later fused back together. Jane, a younger tyrannosaur, carried healed facial bite marks consistent with attacks from another tyrannosaur around her own size. And when researchers examined hundreds of tyrannosaur skull and jaw bones, they found hundreds of healed bite injuries — evidence that violent face-biting may have been a normal part of growing up for these predators. T. rex also possessed one of the strongest bites ever estimated for a land animal, capable of crushing bone with thousands of pounds of force. Which raises a stranger question: How could an animal survive being attacked by another T. rex? This is the fossil evidence behind one of the toughest predators to ever walk the Earth.
