Geschichte: Tucking Mill: actually the name of the house in which W. Smith lived in the 1790s and the place where he began to produce the world's first geological map by interpreting index fossils - thus it's a perfect place for fossil hunting. To me, this oolith indicates a layer which once must have been underneath a surface of shallow water, being a habitat for many creatures.
Geologie: This nice piece is an oolith. It's a sedimentary rock, composed of small pellets, called ooides. They get built in shallow water where a lot of movement happens, for example at a beach. The ooides form when more and more lime is attaching to a grain of sand. Later, the ooide pellets get compacted together and form an oolith rock.
