Maylandsea Foreshore (part of Blackwater Estuary SSSI), MAYLANDSEA , Maldon District, TL907035, Site of Special Scientific Interest
Site name: Maylandsea Foreshore (part of Blackwater Estuary SSSI)
Grid reference: TL 907035
Brief description of site:
The foreshore of London Clay at Maylandsea has yielded vast numbers of fossils, particularly crustacean remains such as lobsters (George & Vincent 1982). Selenite (gypsum) crystals can also occasionally be found. The site is included in Blackwater Estuary SSSI.
Extract from SSSI citation:
Within the Blackwater Estuary, at Maylandsea, a section of 'soft rock' coastline has been identified by the Geological Conservation Review as being of national geological importance.
The site, located on the east bank of Lawling Creek, demonstrates the maximum transgressive extent of the London Clay, and contains a deeper-water fish fauna than is found at Sheppey. These sediments make up the deepest water facies known in the London Clay, and the assemblage reflects this, with species, and proportions of species, within the fauna which are not seen at Sheppey or any other site. Twenty-one taxa have been described from here, mainly based on teeth, but including a skull and 'gaping jaws' of Rhinocephalus planiceps.
