Cotswolds The Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe.

[2] The rocks are exposed from Dorset and Somerset eastwards and northwards through the English Midlands to Yorkshire.

[3] It is present at depth in the Wessex-Weald Basin, where it reaches its greatest thickness of 120 m. The group consists of up to 120 m thickness of oolitic limestones and subordinate sandstones and mudstones laid down during the Jurassic Period.

The ammonite Parkinsonia parkinsoni, an index fossil for the Bathonian,[6] is native to the Inferior Oolite of Burton Bradstock.

[9] A supposed dermal spine long thought to be from a stegosaur is actually a caudal vertebra referable to Archosauria indet.
