Oil Shale - Sedimentary Rocks

Oil shale is a sedimentary rock containing solid and combustible organic matter (kerogen). Oil shale can be burned as any other fossil fuel or it can be heated without oxygen to extract shale oil. Oil shale (variery Kukersite) from Estonia is very rich in fossils (bryozoans, trilobites, brachiopods).
