Lower Cambrian echinoderm plates from Cowley, Shropshire, England

  • S. K. Donovan (a1) and C. R. C. Paul (a1)


Echinoderm plates from the Protolenus Limestone are recognised as belonging to three groups; plates with folded surfaces, plates with bevelled edges and a third group. They are not comparable with other Lower Cambrian echinoderms and may be derived from a genus or genera of eocrinoid which is not known from complete specimens.
