Computer model shows how keyhole-shaped sockets distribute forces compared to round sockets

Not just small arms: Tyrannosaurus rex also had super-small eyes to accommodate its big bite

powerful jaw Tyrannosaurus Rex They held together with such force that they would split the bones of dinosaur prey.But for such a powerful bite, the king Dinosaur had to do one Evolution Tradeoff: It has to accommodate smaller eyes.

In particular, carnivores with skulls longer than 3.2 feet (1 m) tend to have slender, keyhole-shaped eye sockets or sockets as adults, while young carnivores and herbivores of all ages have rounded eye sockets.
