We review the different factors affecting significantly mineral structure and composition of bones. Particularly, it is assessed that micro-nanostructural chemical properties skeleton bones change drastically during burning; micro- nanostructural changes attending those phases manifest themselves, amongst others, in observable alterations to colour, morphology, microstructure, mechanical strength crystallinity. Intense involving also occur fossilization process.

Moreover, bioapatite suffers varying degree extent phase contamination from nearby environment, point rarely fluorapatite single may be found fossil here examined.
