Evidence from the fossil record reveals that the ear region             of the skull changed radically during the evolutionary transition               from reptiles to mammals.  Many of these changes concerned soft-                tissue structures (nerves, arteries, and veins), as evidenced by                various grooves, canals, and foramina in the fossils.  Our                      ability to interpret these bony features in fossil forms is                     severely limited by poor knowledge of soft-tissue structures in                 the ear region of modern mammals.  Detailed anatomical data from                modern mammals will be collected and used to:  (1) reconstruct                  soft-tissue structures in the ear regions of fossil forms and (2)               analyze the evolutionary relationships among the major groups of                mammals.
