My research is directed toward a long-term program on fossil corals, coral-like fossils, and environmental changes during the Great Ordovician Biodiversification Event, Late Ordovician mass extinction, and Early Silurian recovery. It deals with some of the most significant events in Earth history. Tremendous diversification and biotic change occurred during the Ordovician Period (~485–444 million years ago); corals became a major faunal component for the first time. The Late Ordovician mass extinction resulted in one of the largest decreases in biodiversity, and in a reorganization of coral faunas. This was followed by renewed diversification during the Early Silurian recovery (~444–433 million years ago). Analysis of the patterns and processes involved in these events is being integrated with broadly based studies on all aspects and applications of fossil corals and coral-like fossils.
