The marine fossil record contains a myriad of organic molecules, which derive from marine (algae, (cyano)bacteria, archae) and terrestrial organisms living at the time of deposition. These so-called biomarkers contain information which, if properly decoded, can give insight in past climatic and palaeo-environmental changes. This can help in (i) understanding natural and anthropogenic influences on present-day climates and depositional systems, and (ii) deciphering the conditions which have led to sequestration of organic carbon in the geological record, and thus to the formation of marine petroleum source rocks. Sedimentary organic components are derived from biochemicals of primary producers and organisms processing primary produced carbon.
