WebMar 7, 2024 · The progressive phase transition upon the phosphatization process is ascribed to complete evaporation of red P at ~550 °C, as confirmed by thermogravimetric analysis (TGA) in Figure S3a. Further phosphatization at higher temperatures ranging from 750–850 °C led to the reformation of highly crystalline orthorhombic CoP/CC. Soft-tissue fossils, such as those found in the Burgess Shale, are rare. 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.
