In this paper, Dr. Mason used the new Micro-CT facility in Zoology to create cross-sectional and three-dimensional images of the skulls and ear regions of small desert mammals.

The most extraordinary ears were found in a Namibian elephant shrew, in which the volume of the two middle ear cavities together (shaded red in the skull reconstruction) exceeded the volume of the brain. Enlarged middle ear cavities, found in many small desert mammals, are believed to augment low-frequency sound transmission, useful for communication across long distances in a desert environment.
