.... 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...

... 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...

In bone, osteoblast cells control the mineralization of the extracellular collagen protein matrix. When osteoblasts become engulfed in mineral...

... 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...

To track the influence of marine resources on avifaunas we analyzed the carbon, nitrogen, and hydrogen isotope composition of collagen from late Pleistocene vultures...

... fibroblasts multiply and form additional collagen fibres ( Kawanami et al ., 1982 ). This is the process of fibrogenesis and should be distinguished from fibrosis in that the former may be reversible whereas the latter results in progressive lung disease. For further details, the reader is again referred...
