Professional Interests

My primary interests are invertebrate fossils and the depositional environments that produced the rocks in which they are found. In particular, my specialty is trilobites of Cambrian and Ordovician age and their utility for correlation and paleogeographic reconstruction.

Current Projects

My long-term projects all include description of Upper Cambrian and Lower Ordovician faunas and rock units and refinement of the age-correlation possible between such widely separated field areas as the central Appalachians (PA/MD/VA), northern and central Rocky Mountains (MT/WY/CO), northern Mississippi Valley (MN/WI), southwestern U.S. (TX/OK/NM), the Great Basin (UT/NV) and Alaska. Specific topics include (1) the spatial and temporal distribution of microbial (bacterial reefs) and their specialized trilobite faunas, (2) the pattern of faunal turnover at extinction horizons in the Upper Cambrian and Lower Ordovician (both stage boundaries and biomere boundaries), and (3) recognition and interregional/intercontinental correlation of specific, geologically rapid submergence events that left their mark in the very thick limestone-dominated successions of North America.
