Mineralisation of Bone depends on the enviroment that it is deposited in and the relative thickness of the bone. This process can take up to a couple of years to thousands of years. In certain conditions, such as where the minerals in the surrounding enviroment are extremmly soluble, the process will be sped up - for instance, in some places in Australia fossils can be created in a short period of time. Scientists in have now made Petrified wood in the lab in a matter of hours. Minerals in extremely soluble conditions will penetrate bone and other organic matter extremely quickly in the right conditions.
