The Lower and Middle Ordovician Faunas of the Great Basin
Field-Based Trilobite Systematic Projects
Beyond the Ordovician Great Basin project, my lab in engaged in many other studies of Cambrian, Ordovician, Silurian, and Devonian faunas based on new field collections. A majority of these projects feature silicified fossils.
Cambrian–Ordovician Mass Extinctions
Trilobite Evolutionary Faunas
Diversity and Habitat Occupancy
Silicified faunas are excellent for studying biostratinomic processes because trilobite silicification is almost always pervasive: while there are some complications, mostly what you get out is all of the preserved trilobite sclerites that went into the sediment, avoiding the sometimes extreme pitfalls of mechanical sampling biases.
