Paul Martin recently moved from his office at the Desert Laboratory. He remains active and can be reached by e-mail. He occupied an office on the Hill for more than 50 years. Material was placed at the following sites:

Paul S. Martin is Emeritus Professor of Geosciences at the Desert Laboratory of the University of Arizona in Tucson. He is a major contributor to the model of prehistoric overkill as the overriding explanation for prehistoric extinctions of large animals in radiocarbon time (last 50,000 years). With H. E. Wright, Jr., Martin edited Pleistocene Extinctions: the Search for a Cause, Yale University Press, 1967; Quaternary Extinctions: a Prehistoric Revolution, University of Arizona Press, l984, 1989; and is an editor of Packrat Middens, University of Arizona Press, 1990 and of Gentry's Río Mayo Plants, University of Arizona Press, 1998. He is completing a trade book on animal extinctions in near time for the University of California Press.
For more than forty years Paul S. Martin has investigated Pleistocene biotic changes in arid regions. He has studied the biogeography of eastern Mexico, the Pleistocene fossil pollen record of Arizona, and the potential for fossil packrat middens to reveal climatic changes. His interest in the extinction chronology of late Pleistocene large animals has taken him to fossil sites in the four corners of the world. His experiences led to the development of extinction models based on human activity as the main cause of extinctions in near time, the last 50,000 years. An Emeritus Professor of Geosciences, he has taught and conducted research at the University of Arizona's Desert Laboratory on Tumamoc Hill in Tucson since 1957.
