Cretaceous sponges from the Campanian of Misburg and Höver

Locality: Alemannia, Höver

Stichophyma multiformis

Bronn 1837

Stichophyma multiformis is moderately common, particularly in the Lower Campanian of Höver.

Stichophyma multiformis is a roughly cylindrical sponge, commonly with ring-like bulges and with a stem. Hump-like prominences are common. The species may reach sizes to 0.5 meters. As Schrammen (1910) pointed out, Stichophyma multiformis is similar to Jereica polystoma, but it can be distinguished on the basis of the larger, usually very conspicuous ostia covering the outside, while Jereica has only very fine pores.

Locality: Germania IV, Misburg
Height: 120 mm
Width: 80 mm

The apex of Stichophyma multiformis is truncated or slightly convex, with numerous large (5 mm) oscules surrounded by more or less raised rims.

Locality: Germania IV, Misburg
Height: 45 mm
Width: 35 mm

Stichophyma turbinata

Roemer, 1841

Stichophyma turbinata is typically top-shaped, with a truncated upper end, showing numerous rimmed or flat oscules. The species is considerably smaller than S. multiformis, reaching approx. 60 mm in height.
