Abstract

Three bryozoan species are described from the uppermost part of the Velbert Formation (uppermost Famennian, Strunian) from the classical section Ratingen-Cromford (northwestern flank of Velbert Anticline, western Rhenish Massif, Germany). The described fauna includes one new genus Ratingella gen. n., one new species Crustopora fistulosa sp. n., and one species in open nomenclature, Nikiforovella sp. The hitherto known bryozoans from the Strunian of the Velbert Anticline constitute the most important bryozoan fauna from the Famennian 'Condroz Shelf', bordering on the southwestern coast of Laurussia between southwestern England and Pomerania (northern Poland). Coinciding, it is the most diverse European bryozoan fauna from that time slice. Facies differences along the northwestern flank of the Velbert Anticline between a clear-water ramp segment in the southwest and a marl ramp segment in the northeast are responsible for a completely different faunal association. Encrusting taxa diminish towards the north, while erect growing, branched taxa predominate and the general diversity increases. The studied fauna points to connections with the Asiatic part of Russia, Kazakhstan, and China and implies a general Palaeotethyan character for latest Famennian bryozoans in Eurasia.
