A superb very large dorsal exoskeleton in excellent relief. It is complete apart from the tips of the genal spines and the tip of the pygidium and shows the base of the thoracic axial spine and over 20 segments in the pygidial axis - features which clearly distinguish it from E. variolaris. From Dudley, West Midlands, UK.
