Preservation of Mineralized Soft Tissues and Their Imprints on the Shells of Ancient Phosphatic Brachiopods

Аннотация

The linguliformean phosphate-shelled brachiopods from the Lower–Middle Cambrian of the Siberian Platform with preserved molds of the outer layer of their soft bodies or mineralized parts of their soft bodies are described. This type of preservation in the fossil state is closely connected with the burial conditions that determined fast posthumous mineralization of the organic matter.
