Unusual cystoporate? bryozoan from the Upper Ordovician of Siljan District, Dalarna, central Sweden.

Suecipora ebbestadi gen. n. sp. n. (Bryozoa) is described from the Upper Ordovician of Siljan District, Dalarna, central Sweden. This taxon is characterized by long peristome-like tubes with keel-shaped projections, as well as apparent angular kenozooecia. These morphologies are regarded being homologous to the post-Palaeozoic cyclostomes. Colonies of Suecipora are mainly multilayered developed by budding of new sheets from peristome-like tubes. The morphology of Suecipora suggests its adaptation to an environment with soft substrate and strong sediment influx. It is supposed that the colonies of this bryozoan were partially elutriated and experienced fresh water diagenesis. [ABSTRACT FROM AUTHOR]
