Research summary
My research aims to understand the impact fossil data has on our understanding of the relationships of modern organisms, specifically arthropods. This involves the collection and description of exceptionally preserved material from around the world and coding them into an extensive phylogenetic analysis. Once a phylogenetic hypothesis has been obtained it can be used to understand patterns and processes in evolution. Recently I have been studying material from Ordovician sites in Wales, Morocco and the U.S.A. which will then be used as a tool to explore the phylogenetic signal of the “Great Ordovician Biodiversification event”.
