THE FULL STORY

The first time you stand next to a T. rex skull in a museum, the size is shocking. It’s about 5 feet from snout to back - as tall as a 10-year-old kid, just for the head. The skull alone weighs around 200 pounds.

It’s not just big, it’s heavily reinforced. The bones are thick and braced with bony struts, designed to absorb the punishing forces from T. rex’s bone-crushing bite without splitting open. T. rex needed a skull strong enough to clamp down on prey with six tons of force - and still hold together afterwards.

The eye sockets are about the size of softballs, and they face mostly forward. That means T. rex had stereoscopic vision - both eyes working together to judge distance - much like an owl, or like us. It’s one reason scientists think T. rex was an active hunter, not just a scavenger.
