Sometimes organic molecules survive unchanged or with minor changes (e.g. decarboxylation, dehydroxylation, rearrangement. These molecules used to be called geochemical fossils, now they are called 'biomarkers' and can hold critical information about the original material. A biomarker can be any kind of molecule indicating the existence, past or present, of living organisms.The term biomarker is also used to describe biological involvement in the generation of petroleum.
