Six species are new: Heterotrypa ringerikensis sp. nov., Trematopora maculata sp. nov., Amplexopora crassiparietum sp. nov., A. evae sp. nov., Orthopora worsleyi sp. nov., and Mediaporina kiaeri sp. nov. One species is described in open nomenclature: Eridotrypella sp. Trepostome bryozoans dominate this assemblage, both by diversity and abundance. The bryozoans occur in carbonates associated with evaporite minerals and sedimentary structures indicating very shallow depositional settings. ER -
