A sampling-adjusted macroevolutionary history for Ordovician-Early Silurian crinoids

Ecosystem-wide body-size trends in Cambrian-Devonian marine invertebrate lineages

Speciation and extinction in the fossil record of North American mammals

A null biogeographic model for quantifying the role of migration in shaping patterns of global taxonomic richness and differentiation diversity, with implications for Ordovician biogeography

How green was Cooksonia? The importance of size in understanding the early evolution of physiology in the vascular plant lineage

Because of the fragmentary preservation of the earliest Cooksonia-like terrestrial plant macrofossils, younger Devonian fossils with complete anatomical preservation and documented gametophytes often have received greater attention concerning the early evolution of vascular plants and the alternation of generations.

Body size, energetics, and the Ordovician restructuring of marine ecosystems

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.
