Understanding mechanisms for the end-Permian mass extinction and the protracted Early Triassic aftermath and recovery

Modern study of the end-Permian mass extinction in the marine realm has involved intensive documentation of the fos- sil content, sedimentology, and chemostratigraphy of individ- ual stratigraphic sections where the mass extinction interval is well preserved. These studies, coupled with innovative model- ing of environmental conditions, have produced specific hypotheses for the mechanisms that caused the mass extinction and associated environmental stress.

Phanerozoic trends in skeletal mineralogy driven by mass extinctions

Phanerozoic trends in the global diversity of marine invertebrates

How are global patterns of faunal turnover expressed at regional scales? Evidence from the Upper Mississippian (Chesterian), Illinois Basin, USA

Linking biotic patterns across spatiotemporal scales provides a greater understanding of the processes that drive ecological and evolutionary change. Here, we examine how global patterns of biotic turnover are expressed in the structure of regional biotic gradients from the Illinois Basin (USA) during the late Paleozoic ice age (LPIA)— an interval noted for low global rates of taxonomic turnover.
