Abstract

Ten bryozoan species are described from the Tournaisian of Namur-Dinant Basin, Belgium. Five species are new: Leptotrypa hexagona sp. nov., Dyscritella ornata sp. nov., Saffordotaxis spini- gerus sp. nov., Paranicklesopora ornaisa sp. nov., and Spinofenestella nodosa sp. nov. One species Rectifenestella rudis (Ulrich, 1890) is characterised by wide geographical and stratigraphical distribution. Four species are described in open nomenclature: Fistulipora sp. 1, F. sp. 2, Nikiforovella sp., Trepostomata sp. indet. The bryozoan assemblage of Belgium shows palaeogeographical connections with Tournaisian assemblages from some regions of Eurasia and USA.
