Supervisors: Professor Jan Zalasiewicz

Project Overview

James Wilkinson
The sedimentary rocks in the area of Ludlow and surrounding Welsh borderlands contain Graptolite fossils of Silurian age,  which have contributed strongly to global biostratigraphy from this period of Geological time. Despite their importance to this geological interval however, these specimens have not been studied in detail since Ethel Wood's (1900) paper “The Lower Ludlow Formation and its graptolite-fauna”.

Research Questions

  • Systematic analysis of curated graptolite specimens held by BGS and other bodies.
  • Carry out a taxonomic reassessment of component species.
  • Evaluate palaeoclimatic and palaeoceanographic restraints resulting in the restrictions to biodiversity and eventual extinction.
