The Blue Circle Industries pic Westbury Works is a major marine vertebrate-bearing exposure in the Lower Kimmeridge Clay of Wiltshire. The quarry faces have yielded important chelonian, ichthyosaurian, crocodilian and plesiosaurian remains. The most recent discovery is a large pliosaurian skeleton found during the summer of 1994. The partial skeleton, provisionally identified as Pliosaurus, consists of a skull and mandible (approximately 1.8 m in length), with associated disarticulated postcrania enclosed within large carbonate concretions. The skeleton is associated with abundant fossil wood and shell debris, indicating a possible period of turbulent current activity in the vicinity of the carcass prior to burial.
