E earliest serpulids and sabellids presumably began to calcify inside the
E earliest serpulids and sabellids presumably began to calcify inside the Aragonite II seas on the Permian Period [58,68], and aragonite is presumed to be the primitive biomineral for each serpulids and sabellids [32,69]. It really is possible that the dominant mineralogy of serpulids changed to calcitic for the duration of the extreme Calcite II seas with the Late Cretaceous [70]. It can be fascinating that the bryozoans, one example is, are primitively calcitic, and they appeared during an epoch of calcitic seas (Late Cambrian), whereasMinerals 2021, 11,12 ofboth MAC-VC-PABC-ST7612AA1 site molluscs and serpulids are primitively aragonitic and appeared through an epoch of aragonitic seas in the Early Cambrian and Permian, respectively. The other groups of polychaetes played only minor roles in the evolution of polychaete biomineralization, and their biomineralization systems are primitive as in comparison with serpulids.Figure 10. Evolution of serpulid tube microstructures. Phylogenetic relationships of serpulid genera derived from Kupriyanova et al. [67]. Numbers indicate: 1, unoriented structures; two, semi-oriented structures; 3, oriented prismatic structures. Serpulids with dominantly calcitic mineralogy or with mixed composition are marked with yellow, and genera with dominantly aragonitic mineralogy are marked with blue.8. Conclusions Fifteen tube microstructures happen in serpulids, whereas in sabellids and cirratulids, only two sorts of tube microstructures have been described. Serpulids possess the most advanced biomineralization program amongst the polychaetes and in annelids normally.Minerals 2021, 11,13 ofThey can construct tubes from calcite, aragonite, or even a mixture of both polymorphs. The biomineralization of sabellids and cirratulids is far more primitive and they generate only two aragonitic microstructures. Sabellids and probably also cirratulids are organic matrixmediated biomineralizers, whereas the biomineralization program of serpulids has remained more controversial. Nevertheless, the microstructural patterns of serpulid tubes are very best explained by the organic matrix-mediated biomineralization model.Funding: This study was funded by the Estonian Study Council, grant quantity PRG836, plus the Paleontological Society Sepkoski Grant 2021.
