The geology of East Sussex is defined by the Weald–Artois anticline, a 60 kilometres (37 mi) wide and 100 kilometres (62 mi) long fold within which caused the arching up of the chalk into a broad dome within the middle Miocene,[1] which has subsequently been eroded to reveal a lower Cretaceous to Upper Jurassic stratigraphy. East Sussex is best known geologically for the identification of the first dinosaur by Gideon Mantell, near Cuckfield,[2] to the famous hoax of the Piltdown man[3] near Uckfield.
The county’s chalk has provided a world-class stratigraphic marker giving a great deal of detail in Cretaceous Chalk palaeoecology and palaeontology while in the east of the county on the Kentish border the Dungeness Foreland is important for the study of geomorphology and Holocene sea level fluctuations.
