This may belong in the Off topic forum. I understand corals produce fluorescent proteins/pigments to manipulate the surrounding light. This is to protect the Algae's they host from too much light or to even enhance low light. Ok a coral will extract certain minerals from the water & food to produce these fluorescent proteins . Can these proteins end up in the coral's skeleton? I was talking to a friend who collects fluorescent rocks. I tod him about some old fossilized brain coral heads I have & he thinks that in the center of these rocks there may be these fluorescent proteins in some mineralized form. I understand that Calcium flouride will fluoress under certain UV lighting. Think this is possible?
