【 摘 要 】

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