Cretaceous sponges from the Campanian of Misburg and Höver |
Phyllodermia (Cladodermia) | Schrammen 1924 |
Cladodermia colosseaSchrammen 1924Cladodermia colossea has a rounded cone- or pear-shaped habit and a broad base with many short, root-like processes. The base is covered with a dense cortex and with phyllotriaenes. In the cortex-free parts, the sponge surface is pitted with numerous mm-wide pores. The specimen in the picture shows a typical system of anastomosing furrows near the base and around the paragester. |

The second example of Cladodermia colossea is more elongate in shape. It shows typical wart-like rootlets on one side of the sponge. It is thought that these may have developed after the sponge has toppled. |
