Short note on three species of Ordovician Orchocladina (Demospongea, Porifera) Naturalis
Rhebergen, F..
The type and only specimen of Fibrocoelia tubantiensis Van Kempen, that was housed in the palaeontological collection of the Geological Institute of the University of Amsterdam, has been reposited in the Netherlands Centre for Biodiversity – Naturalis, Leiden, the Netherlands. Syltrochos pyramidoidalis Von Hacht, placed in an uncertain order and family by Finks & Rigby, is revised on the basis of new material. This has revealed that the skeleton is composed of spheroclones, so that the species has to be assigned to the Astylospongiidae von Zittel. The species name Carpospongia langei Von Hacht is invalid, being a junior synonym of Carpospongia pogrebowi Asatkin.

A new Late Ordovician erratic anthaspidellid sponge (Porifera) originating from Baltica Naturalis
Rhebergen, F..
The new anthaspidellid taxon Brevaspidella dispersa is erected for specimens recovered from the Late Ordovician sponge assemblages of the island of Gotland, Sweden and the Dutch-German border region. In the latter area, they are collected from Early Pleistocene fluvial deposits of the Baltic River System, whereas those from Gotland are part of Late Pleistocene glacial or fluvio-glacial deposits. The provenance of both assemblages is uncertain, but they probably originated from an Ordovician basin in the northern Baltic Sea or the Bothnian Gulf, west of Finland. As yet, Brevaspidella dispersa gen. et sp. nov. is restricted to the Gotland-German-Dutch sponge association and has not been found in the assemblage of nearly-coeval ‘lavender-blue cherts’ and...

A remarkable new Middle Sandbian (Ordovician) hexactinellid sponge in Baltic erratics Naturalis
Botting, J.P.; Rhebergen, F..
A new species of complex hexactinellid sponge, Haljalaspongia inaudita, is described from fluvially transported blocks found in northwestern Germany, near the Dutch border, but which probably originated from the eastern Baltic region. The heavily folded wall is composed of multiple spicule layers, including dermal and gastral layers of acanthohexactines, and a central layer of sub-parallel monaxons. The monaxial layer is lined on one side by a reticulate array of smooth monaxons. The sponge is difficult to assign to any known fossil or recent group, but shares some features with the dictyospongioid family Docodermatidae.
