Through a glass darkly: taxonomy, phylogeny, and biostratigraphy of the Olenellina

Abstract

The Olenellina is an exclusively Early Cambrian trilobite suborder that dominates the later Early Cambrian trilobite faunas of Laurentia and constitutes a lesser component of the trilobite faunas of Siberia, Baltica, Avalonia, and the western sector of Gondwana/peri-Gondwana (Morocco, Spain, and eastern (;ermany). The classification of the Olenellina presented here will appear in the revised edition on Trilobita of the Treatise on Invertebrate Paleontology.
