Marine Transgression
Marine Transgression
This outcrop tells the history of a change in the ancient sea level. At the bottom are fossils of 'Naiades', a type of bivalve found only in fresh water. Above it is a layer of swamp deposits, with a pale seatearth or fossil soil on top. Then there is a layer of shales laid down in brackish water, capped by layers bearing NT2787 : Crinoid Fossils, an exclusively marine fossil, and a layer of limestone formed in a shallow sea. So the environment at this point changed from river, to swamp, to dry land, and then the sea began to encroach, finally submerging it completely.
