Biocrystals of calcite are frequent as they are employed by many phylaeof organisms in shells, eggshells, teeth, spines or sensoric apparatus.The calcite phase in these materials occurs in a range of constitutions,from polycrystalline fabrics to “single-crystals”. We demonstratesystematics of calcite biocrystal architectures, from the hybridcomposite mesocrystal fibres of brachiopod and mollusc shells, via thesubmillimeter-sized hybrid composite crystal aggregates formed bymesocrystal fibres with both morphological co-orientation and latticeco-orientation, to more complex purpose-oriented multiplex compositecrystals of echinoderm teeth, which feature a high degree ofsingle-crystal-like 3D orientational correlation of microstructuralelements of different morphology and composition. These systematics relyon observations by electron backscatter diffraction (EBSD) and TEM.
