Bryozoan bioherms attaining up to a few meters in length and one meter in thickness. The bioherms are built up by cyclostomate and cheilostomate bryozoans but the frame-building assemblage is monospecific in places, consisting of Fasciculipora janinae sp. n. Branching colonies of the new species are so
variable that their isolated fragments might be easily misidentified as belonging to distinct species, or even genera.
