A limestone rock surface has been chemically weathered (involving rainwater) which has caused small channels and a rough surface texture. Embedded in the limestone are various fossils which are slightly more resistant to weathering and,therefore,protrude slightly from the surface. The rock formation is known as Schrattenkalk and is from the Cretaceous | |
