Class Gymnolaemata includes the uncalcified order Ctenostomata and the youngest order, Cheilostomatida, with typically box-shaped zooids; it is this speciose (4921 extant species) order that provides most mineralogical variability (Bock and Gordon, 2013; Smith et al.
1998) revealed a complex mineralogical suite in the marine bryozoan classes Gymnolaemata and Stenolaemata.
