    Current Projects

    Since retiring from NAU Geology in 2009, most of my efforts have been towards creating paleogeographic maps. Most of these maps are within five series 1: global, 2: North America, 3: Europe, 4: Southwest North America, and 5: Western Interior Seaway (Jurassic and Cretaceous). These maps are continuously updated and new maps are added to each series. I have continued to publish scholarly works and a list of my publications can be accessed on this web page. For more information about these paleogeographic maps please visit my web page
