In some cases their internal organs are replicated in phosphate. The phosphate mainly comes from the tissue itself, and may later be replaced by calcium carbonate. A low pH makes CaCO3 less likely to precipitate, clearing the way for phosphate to be laid down. This is facilitated by the absence of oxygen in the decaying tissue.
