As opposed to most human made materials, biologic structural materials employed for skeletons|or teeth show a hierarchical architecture, where the components of organic macromolecules and|mineral substance are inter-weaved on many length scales in order to form a composite material.|In the overall skeleton the organic biopolymer fibres provide flexibility and tensile strength while|the mineral provides a high elastic modulus, compressive strength, hardness and resistance to|abrasion. The hierarchical composite architecture provides fracture toughness. The morphogenesis|of the biomaterial as a whole and of the mineral particles is guided by the organic matrix. In|this paper we use the example of rhynchonelliform brachiopods to discuss the nano- to macroscale|assemblage.
