Dinosaurs Were Airheads CT Scans
Paleontologists have long known that dinosaurs had tiny brains, but they had no idea the beasts were such airheads.
A new study by Ohio University researchers Lawrence Witmer and Ryan Ridgely found that dinosaurs had more air cavities in their heads than expected. By using CT scans, the scientists were able to develop 3-D images of the dinosaur skulls that show a clearer picture of the physiology of the airways.
“I’ve been looking at sinuses for a long time, and indeed people would kid me about studying nothing—looking at the empty spaces in the skull. But what’s emerged is that these air spaces have certain properties and functions,” said Witmer, Chang Professor of Paleontology in Ohio University’s College of Osteopathic Medicine.
