Fossils will be collected from middle Miocene deposits in the                   Mojave Desert of southern California.  This work is undertaken to               develop a secure biostratigraphic framework for Hemingfordian                   mammal assemblages, which when combined with the existing                       Barstovian mammal assemblages will permit reliable identification               of the boundary between Hemingfordian and Barstovian land mammal                ages.  Preliminary study has indicated the Mojave Desert is the                 best area to develop a dependable Hemingfordian/Barstovian                      boundary.  The Cenozoic history of mammals is punctuated with                   brief but significant intervals of intercontinental dispersal by                land mammals.  Middle Miocene is one of these intervals, with the               Hemingfordian/Barstovian boundary possibly the high point in                    appearance of immigrants.  Secure chronologic resolution of that                boundary is necessary to test hypotheses about the timing of                    global climatic-eustatic sea level events as a trigger mechanism                for intercontinental dispersal of land mammals.  This project will              provide primary data for testing these hypotheses and should                    clarify the interaction of dynamic global processes in the                      evolution of terrestrial biota.
