Oxford Clay is a dig site in Jurassic World Evolution.

InGen Database Description

The Oxford Clay Formation covers much of south-east England, stretching out from Dorset and all the way up to Yorkshire. It contains several members which date from the middle Callovian to the Oxfordian stages of the Middle and Late Jurassic epochs, 166 and 160 million years ago. It overlies the Kellaways Formation and sits beneath the West Walton Formation.

The region records a range of environments, predominantly coastal and marine with mudstone, fissile shale and limestone.

Dinosaur eggs have been found here, particularly in the Lower Oxford Clay in Cambridgeshire. Fish and invertebrate fossils are also quite common. Most fossils originate from the upper faces of the Stewartby Member and the Weymouth member.

The abundant marine fossils are likely due to a large part being below sea depth, and with warm and nutrient-rich water that supported a rich ecosystem. The deeper water would have been lacking in oxygen, and so lack in predation on the sea floor allowed more carcasses to become fossils.
