The Ordovician-Silurian witnessed the 2nd greatest mass extinction ever on Earth. Crinoids were no exception, with early Silurian crinoids being very different from those that were in the Ordovician. My personal quest to understand this aspect of evolutionary history began in graduate school. With several starts and stops, I have now been able to study Early Silurian crinoids from Ohio, Kentucky, Quebec, and Estonia. We now know how and why it happened and how the biosphere recovered.
William I. Ausich received his B.S. degree at the University of Illinois, and A.M. and Ph.D. from Indiana University. In 1978 he joined the faculty at Wright State University and moved to Ohio State University in 1984. He retired in 2013 and is currently an Academy Professor in the School of Earth Sciences. Among other responsibilities, he served terms as Chair of the Department of Geological Sciences and Director of the Orton Geological Museum. He has written or co-edited nine books and more than 300 journal articles and guidebooks. His research has focused on the evolutionary paleoecology of Paleozoic marine communities with a special emphasis on crinoids.
