| Sponge heights and oscular diameters were measured using ImageTool. |
| The external membrane in many Spongillid is prolonged round and above the oscula so as to form an oscular collar. |
| Few long marginalia projecting from the oscular margin may belong to an oscular spicule rim. |
| The oscular margin of the new genus is composed of diactines that are parallel to the main body axis. |
| The specimen is a large, broadly obconical sponge with broken base and subhemispherical uppermost oscular margin. |
| The sponge's basal part, oscular part and side part occur at different levels within the mud layers, which might have resulted from rapid burial. |
