It is also standard to coat fossils during their extraction and transport.
Acetone is sometimes used while extracting fossils, because it dissolves dirt.
Fossil corals have the unique advantage that they ...In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.Although relative dating can work well in certain areas, several problems arise. It is produced in the upper atmosphere by radiation from the sun.(Specifically, neutrons hit nitrogen-14 atoms and transmute them to carbon.) Land plants, such as trees, get their carbon from carbon dioxide in the air. The same is true of any creature that gets its carbon by eating such plants. Suppose such a creature dies, and the body is preserved.
