Figures & data
Figure 1. Mineralogical compositions of cheilostome bryozoan biotas from different latitudes. Note the increasing proportion from the poles to the tropics of species biomineralizing aragonite, either monomineralically (a, pale grey) or bimineralically with calcite (b, mid grey), and the corresponding decrease in calcitic species (c, dark grey). As noted by Kuklinski & Taylor (Citation2009), the one record (Borisenko & Gontar Citation1991) of an aragonitic bryozoan species in the Antarctic is questionable (see also Krzeminska et al. Citation2016 who found no aragonitic bryozoans in their samples from King George Island, Antarctica).
