John Flynn's research emphasizes mammalian paleontology and systematics, and paleomagnetism and geochronology. Current research uses DNA sequencing and anatomy of fossil and living taxa to analyze the higher-level evolutionary relationships of the Carnivora and rates of molecular, taxic and morphological evolution. Recent field work has yielded new fossil mammal faunas, providing new insights into the biogeography, temporal history and evolution of the highly endemic South American mammal fauna, and the age and patterns of change between early Cenozoic and North American mammal faunas. Bill Turnbull's current studies of mammalian systematics and evolution focus on late Tertiary and Pleistocene mammalian faunas of Australia, and the 50 million-year-old mammalian fauna of the Washakie Formation in Southwestern Wyoming, with current emphasis on uintatheres and marsupials. Other projects examine the functional anatomy of the masticatory musculature of the Eocene taeniodont Stylinodon, the multituberculates of the Early Cretaceous (Trinity Group) of North Texas, and problems in paleopathology and taphonomy.
