... of cortical bone shows collagen fibrils, with their characteristic periodic banding, which are mineralized with elongated apatite crystals oriented with their c -axis parallel to the collagen fibers ( Fig. 1C ). The size of crystals in the sample of cortical bone is about 47 × 6 nm. On the other hand...

.... 2008a , 2008b ). Early diagenetic processes specific to bone include the removal of soft tissues (i.e., muscle and skin), degradation of collagen (abiotic and biotic), and initial chemical and structural changes to the mineralized component of bone, bioapatite, ultimately resulting in decomposition...

... helps to give the nacre of these materials a fracture toughness that is approximately 1000 times greater than that of pure aragonite ( Zaremba et al. 1996 ; Nudelman et al. 2007 and references therein). Another type of composite is bone, a family of materials built up from mineralized collagen...

... containing internal sediment (poly-mud fabric). In Holocene sediment, this texture develops by calcification of degrading extra-cellular collagenous matrix (ECM) of siliceous sponges. ECM calcification of siliceous sponges is evident throughout the Phanerozoic, and the related polymud fabric is a diagnostic...

... ). As noted above, several families of proteins associated with the collagen matrix are involved in regulation of the mineralization process. Some of these proteins have multiple functions beyond their role in mineralization ( Zhu et al. 2007 ). The proteins include phosphorylated proteins, proteoglycans...

... analyses of the periderm of the living relative Rhabdopleura , indicate that it was originally collagen. This anomaly was previously interpreted as the result of replacement by macromolecular material from the surrounding sediment. New analyses suggest that the aliphatic composition of graptolite periderm...
