"Phosphatic fossilization has occurred in unusual circumstances to preserve some extremely high-resolution microfossils in which careful preparation can even reveal preserved cellular structures. Such microscopic fossils are only visible under the scanning electron microscope. See more Large quantities of phosphate are required, either from seawater or from the tissues of the decaying organism.
