(A) Proposed holistic schematic framework for the reconstruction of fossil colour. Solid lines indicate confirmed steps; dashed lines indicate potentially useful, but yet untested, steps in palaeocolour reconstruction. (B) Sediment‐encased maturation can be used to experimentally validate taphonomic changes in fossils.
