The Oxford Clay (or Oxford Clay Formation) is a Jurassic marine sedimentary rock formation underlying much of southeast England, from as far west as Dorset and as far north as Yorkshire. The Oxford Clay Formation dates to the Jurassic, specifically, the Callovian and Oxfordian ages, [ 1 ] and comprises two main facies .
Cetiosauriscus was found in the marine deposits of the Oxford Clay Formation alongside many different invertebrate groups, marine ichthyosaurs, plesiosaurs and crocodylians, a single pterosaur, and various dinosaurs: the ankylosaur Sarcolestes, the stegosaurs Lexovisaurus and Loricatosaurus, the ornithopod Callovosaurus, as well as some unnamed ...
The cutting exposes limestone and clay laid down in mid-Oxfordian stage of the Late Jurassic, around 160 million years ago. The deposit is part of the Stanford Formation, and the clay appears to have been deposited in a channel between coral reefs which then covered the Oxford area.

Furzy Cliff consists of Oxford Clay with a thin Corallian limestone layer on top. [2] Mudslides frequently occur on the narrow undercliff and the base is mainly made up of clay material. [ 3 ] [ 4 ] Fossilized examples of Gryphaea dilatata , commonly called "devil's toenail", an extinct species of Jurassic oyster, and Metriacanthosaurus parkeri ...
Peloneustes is known from the Peterborough Member (formerly known as the Lower Oxford Clay) of the Oxford Clay Formation. [2] While Peloneustes has been listed as coming from the Oxfordian stage (spanning from about 164 to 157 million years ago [ 1 ] ) of the Upper Jurassic, [ 7 ] the Peterborough Member actually dates to the Callovian stage ...
The underlying geology is Cornbrash limestone, with adjacent Oxford clay. [2] Within the clay can be found deposits of stone which can take on a very high polish, earning them the name "Melbury marble". [3] The village is mentioned in the Domesday Book as a possession of the Arundell family, and remained so until the 19th century.
Muraenosaurus was initially discovered in the Oxford Clay which represents an ancient sea that was both shallow, with an average depth less than 50 meters, and warm (20 °C). [13] [14] The Oxford Clay deposits are found in southern England and parts of France. The sea was abundant with nutrients and light filtered easily through the shallow ...
The Oxford Clay Formation where Loricatosaurus remains have been found. Loricatosaurus is known from remains previously assigned to Lexovisaurus that were first discovered at the Fletton brick pit in the Oxford Clay Formation, Fletton, Peterborough, England, by Alfred Leeds during November 1901. [2]
