The contribution of Karoo fossils. The team found that the inner ear canals' geometry adapted to a relatively abrupt change in endolymph viscosity some 233 million years ago, indicating that the ...

"This distinctive inner ear anatomy reflects enhanced sensitivity and more rapid response to head motions," co-author John Flynn says in a press release.

To help pin down the metabolic mystery, the group of paleontologists tapped a surprising piece of anatomy: the inner ear—the shape of which is influenced by an animal’s body temperature.
