The middle Cambrian Ptychagnostus punctuosus and Goniagnostus nathorsti zones in Vastergotland, Sweden

• New trilobite discoveries from eight localities in Vastergotland, south-central Sweden, demonstrate that the middle Cambrian Ptychagnostus punctuosus and Goniagnostus nathorsti zones are present in most Lower Palaeozoic outcrop areas of Vastergotland, though as a thin and impersistent conglomeratic limestone, up to approximately 15 cm thick. These zones have not previously been recognised in Vastergotland, except for a thin bed of limestone on Hunneberg.
