The Middle Cambrian Paradoxides paradoxissimus Superzone on Öland, Sweden

摘要: Trilobites from the Middle Cambrian Paradoxides paradoxissimus Superzone on Oland are reviewed, including species found in glacial erratic boulders Germany and Denmark. The fauna recorded contains 20 10 agnostids. succession, up to 70 m thick, comprises Aleklinta Member of Borgholm Formation (previously known as Paradoxissimus sandstone or siltstone) a thin overlying conglomerate, here informally referred Morbylilla forming base Alum Shale Formation. Granulata Conglomerate, limestone layer previously correlated with Exsulans Limestone, forms Member. It has yielded several characteristic Triplagnostus gibbus Zone, e.g. Ctenocephalus exsulans, Bailiella tenuicincta, Solenopleura parva, Parasolenopleura aculeata T. gibbus. gibbus, Ellipsocephalus lejostracus P. aculeata, all indicative Zone.
