Smokejack Clay Pit is a 56-hectare (140-acre) geological Site of Special Scientific Interest east of Cranleigh in Surrey. [1] [2] It is a Geological Conservation Review site. [3] [4]
This site exposes Lower Cretaceous rocks of the Weald Clay Group, which have been studied since 1983. Fossils of six orders of insects have been recorded and an unusual level of details has been preserved. It is the best Weald Clay reptile site, with crocodile teeth, coprolites and part of an Iguanodon . The holotype specimen of the fish eating theropod dinosaur, Baryonyx walkeri was discovered on the site in January 1983. [5] [6]
The ruins of Ewhurst Brickworks exist near the Smokejack Clay Pit, of which clay was extracted for the Ewhurst Brickworcks as early as the 1940s under A. Hone & Sons Ltd. The surviving ruins date back to the 1960s and were previously known as the Smokejack Brickworks, which closed down during the 1980s. The brickwork company moved to a new building in 2017 or 2018 which is 1 kilometre (0.62 mi) south of Walliswood.
Weald Clay or the Weald Clay Formation is a Lower Cretaceous sedimentary rock unit underlying areas of South East England, between the North and South Downs, in an area called the Weald Basin. It is the uppermost unit of the Wealden Group of rocks within the Weald Basin, and the upper portion of the unit is equivalent in age to the exposed portion of the Wessex Formation on the Isle of Wight. It predominantly consists of thinly bedded mudstone. The un-weathered form is blue/grey, and the yellow/orange is the weathered form, it is used in brickmaking.
