Division B1/B2 of the London Clay (Isselicrinus zone)
Exposure on the South, Swaleside, of the Isle of Sheppey
This site is an inland riverside exposure. The site is adjacent to what was in the past a cement manufacturing and copperas settlement which has long since gone with only the remains of a disused dock and a number of concrete foundations remaining. the total length of the site is 750 metres and represents an in situ exposure of the london clay. Collecting is restricted to the small accumulations of gravel at the base of the low cliff adjacent to the bird reserve. Although the frequency of finds is low, some important specimens have been found. This exposure is much older than the clays of the North side of the Island and represent a more tropical incursion, hence the frequency of the little crinoid Isselicrinus subbasaltiformis and the different fossil crustacean fauna to be found.
