While in many animals, including most dinosaurs, the eye socket is just a circular hole in the skull housing the eyeball, this is very different in large carnivores.

This research, by scientists at the University of Birmingham, was published today (August 11, 2022) in Communications Biology.

Stephan Lautenschlager, University of Birmingham.

Stephan Lautenschlager, Senior Lecturer for Palaeobiology at the University of Birmingham and author of the new study, analyzed the shape of the eye sockets of ca.

500 different dinosaurs and related species.

Lautenschlager tested what purpose these unusual eye socket shapes could have by using computer simulations and stress analysis.

However, if these were replaced with other eye socket shapes stresses were significantly reduced.

Lautenschlager added: “In these species, just the upper part of the eye socket was actually occupied by the eyeball.
