At Dimlington Cliff, basement till from the
Quaternary period (including Dimlington Silts) rests on
chalk bedrock. Organic deposits within these strata have allowed
radiocarbon dating to be applied to this sequence. The Dimlington silts are interpreted as lake deposits, which accumulated prior to the Skipsea Till glacier advance approximately 18,000 years Before Present. The term Dimlington stadial has been applied to date estimates of the
Last Glacial Maximum in Britain. Fossils from the Lower Jurassic exposed in limestone boulders here include the
ammonites Dactylioceras commune (genus
Dactylioceras),
Hildoceras bifrons and fossils from the genera
Arnioceras and
Peronoceras. Other fossils found here include bivalve fossils from the genera
Gryphaea and
Cardinia,
brachiopods from the genus
Productus and the coral genus
Lithostrotion. A wide variety of
glacial erratic rocks are scattered along the foreshore including some from the
Pennines,
Lake District,
Scotland, the Scottish Borders and
Scandinavia. == Land ownership ==
