    The Furongian Alum Shale at Nygård, Hunneberg, Sweden, has been sampled for trilobites. The section is ≥12.20 m thick and comprises a relatively thick Olenus superzone, overlain by more condensed Parabolina, Leptoplastus, Protopeltura and Peltura superzones. The section is truncated low in the Peltura superzone, presumably due to late Furongian uplift.
