A former bryozoan Neuropora pustulosa (Roemer, 1839) from the Lower Hauterivian northwestern Germany is redescribed as a ceratoporellid sclerosponge. The systematic replacement of N. pustulosa is justified by the discovery of monaxonid spicules entrapped in its calcareous skeleton. The relation of N. pustulosa to recent and fossil sclerosponges is discussed. New order Muraniida including one new family Muraniidae based on the recently established genus Murania Kaźmierczak is here proposed.
