Scientists: tyrannosaurs sacrificed their eyes for powerful jaws

Computer reconstructions of the skull of dinosaurs by researchers at the University of Birmingham showed that large predatory animals, such as those with strong jaws, have unusually shaped and long eye sockets. Communications Biology published the article.

Computer modelling of the skulls from about 500 dinosaur species, including tyrannosaurs, showed that the eye sockets were too round to cause high mechanical stress in the bones. The strong jaws of these dinosaurs maintained the skull stability. Therefore, the eyes sockets were slightly longer. The eyeball occupied the orbit in this instance. This caused a decrease in the size and proportion of the eyes to the skull. The Tyrannosaurus Rex’s eyes would have been 30 cm wide and almost 20 kilograms heavier than the 13 cm and 2kg that was estimated.

However, this problem is only relevant to predatory owners with larger skulls than a meter. Most herbivorous species, as well as young carnivores, have a round socket in their eyes.
