Abstract

The colonial rhizangiid genus Sclerangia n. gen. is described from the Miocene of the USA (Chipola Formation, Florida). The new genus is characterized by plocoid to subcerioid polyp integration, cylindrical to subcylindrical or tympanoid corallites, and an endotheca that is generally absent or made of a very small number of vesicular dissepiments. Compared to other rhizangiid genera, the new taxon is characterized by rather weakly dentate septa. In addition, the new genus differs from all the rhizangiid genera by its consistent encrustation of dead gastropod shells that are inhabited by sipunculid worms.
