Phosphatization fossil definition

WebIn some cases microbes control the phosphatization, and the remains of the microbes that fed on the preserved tissue form the fossil. In other, the tissue itself is the source of phosphate and its phosphatized remains form the fossil. In the intermediate case the phosphatized tissue retains the impressions of the phosphatizing microbes.
