A detailed investigation of Phosphatocopina
Fossils and Strata, Number 49: Morphology, Ontogeny, and Phylogeny of the Phosphatocopina (Crustacea) from the Upper Cambrian Orsten of Sweden presents a detailed look at Phosphatocopina through the rigorous lens of modern scientific study. Fully examined here in study form, this monograph details methods, materials, systematics, phylogenetic analysis and more to bolster discussion and back analyses of comparative morphology. Extensive figures and photos clarify qualitative data, while detailed explanation of analysis methods provide a firm foundation for conclusions and future research.
