The chemical analyses of fossils and also of living organisms led to the discovery of new bioactive pigments, and also confirmed that the core structures of these pigments had been preserved during the fossilization process. The existence of these quinoid pigments also leads to several interesting questions related to their stereochemistry and the photoactivation of their bioactivity. %$ 035SUBSAN
