Using GIS to study palaeobiogeographic and macroevolutionary patterns in soft-bodied Cambrian arthropods
TL;DR: A newly developed occurrence database is used in conjunction with Geographic Information Systems analysis and PaleoGIS to quantitatively reconstruct geographic distribution patterns of primarily soft-bodied arthropod species, showing both statistically larger geographic ranges and greater stratigraphic longevities than co-occurring trilobites.

The Nature of Evolutionary Radiations: A Case Study Involving Devonian Trilobites
TL;DR: A view of evolutionary radiations driven fundamentally by external abiotic factors—geology and climate—that cause range expansion and opportunities for geographic isolation with resultant rapid speciation is presented.
54
Paleontological Patterns, Macroecological Dynamics and the Evolutionary Process
TL;DR: It is argued that Darwin recognized but downgraded or de-emphasized several of these important patterns, and what a renewed emphasis on these patterns can tell us about the evolutionary process is considered.
53
Documenting a significant relationship between macroevolutionary origination rates and Phanerozoic pCO2 levels
TL;DR: It is shown that the rates of diversification of the marine fauna and the levels of atmospheric CO2 have been closely correlated for the past 545 million years, suggesting that one or more environmental variables controlling CO2 levels have had a profound impact on evolution throughout the history of metazoan life.

Disparity and constraint in olenelloid trilobites and the Cambrian Radiation
TL;DR: In this species-rich clade, there is no evidence that morphological changes were becoming either increasingly constrained or less flexible in one of the dominant Early Cambrian metazoan clades as it passed through the Cambrian Radiation.
