Paraspelaeum obductum

Schrammen 1924

Schrammen (1924) described Paraspelaeum obductum from Misburg by as a moderately abundant species. However Paraspelaeum obductum, is easily mistaken for some whimsical form of Turonia, and this may explain its late discovery.

The specimen of Paraspelaeum obductum shown here has an irregular, more or less nodular shape. The sponge is covered with a dense dermal surface layer except for some depressed areas. According to Schrammen (1924), some of the depressions may communicate with the paragastral cavity, but this feature may become visible only in sections.

The skeleton of Paraspelaeum obductum consists of zygosed tetraclone desmas with smooth arms. The dermal scleres are dichotriaenes.
