Old name: Protospongia rhenana Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 25:"The large sponge has the outline of a vase, flask or bowl. It has mainly bundled diactines of the first order, which are woven into a rectangular mesh, but in contrary to Retifungus are not coiled (fibre optics network). In addition, the sponge has a lot of small triaxones of the second order lying in one plane, which radiate hexagonal (so called hexatines) or possibly also tetra radial (stauracts), because of the reduction of one of the axes of a triaxon."
