Cretaceous sponges from the Campanian of Misburg and Höver
Tetillopsis Schrammen 1910

Locality: Teutonia, Misburg

Tetillopsis longitridens

Schrammen 1910

The image shows the radiating pattern of exceptionally long (up to 20 mm) megascleres which comprise amphioxes and protriaenes (see bottom figure).

Locality: Teutonia, Misburg
width: 35 mm

The second example is smaller, but more complete. However, the shafts of its triaenes are slightly swollen below the bifurcation while those of the first example and those shown in the figure below do not show such swellings. Hence the identification is uncertain.

Tetillopsis bears many similarities to modern members of the Family Tetillidae ("golfball sponges").
