Abstract [en]

During the Ordovician, deep-water graptolitic mudstone and shale formed in what is now the classical succession at Fågelsång, southern Sweden. Previously, only one gastropod species was described from the succession, but during this study diverse tergomyan and gastropod assemblages have been recognized both from outcrop and drill-core collections. The material spans the Sularp Shale through the Lindegård Mudstone (Nemagraptus gracilis − Dicellograptus complanatus Zones; Sandbian − Katian, Viru − Harju regional stages). Altogether 14 species are described; two tergomyan, five bellerophontoid gastropods, and six anisostrophically coiled gastropods. Three taxa (Tritonophon, Tetranota and Holopea) are found in the Lindegård mudstone. The first record of Tritonophon in the Ordovician of Baltoscandia occurs in the Fågelsång and nearby Röstånga area. The remaining taxa are from the Sularp, Skagen, and Mossen formations. Specimens may have been transported into the area from shallower settings, while species of Peelerophon, Cyrtodiscus, Joleaudella, and Sinuites, are interpreted as having been part of the local benthos. With the exception of Bucania and Deaechospira, no other taxa are common to the hitherto described gastropod fauna of the coeval Dalby Limestone in other parts of Sweden. The Fågelsång assemblages have more in common with the slightly older or coeval fauna of the Elnes to Arnestad formations in the Oslo Region (e.g. Joleaudella, Sinuites, Mestoronema, Pararaphistoma). The Sandbian taxa show similarities with peri-Gondwanan faunas (e.g. Peelerophon, Cyrtodiscus). Both Peelerophon and Cyrtodiscus are for the first time recorded from Baltoscandia. The hitherto endemic Baltoscandian taxon Deaechospira may also be recognized in Bohemia and Morocco.
