The KIMMERIDGE CLAY is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea.[1] This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, plesiosaurs and ichthyosaurs, as well as a number of invertebrate species. This is also the soil responsible for one of my favorite wines. Crisp,
mineralistic Chablis.
