St James' Pit is a geological Site of Special Scientific Interest in Norwich in Norfolk, England. It is a Geological Conservation Review site within Mousehold Heath, which is a Local Nature Reserve. This site has been designated because of its jaw and vertebra fossils of '' Liodon'' and ''Mosasaurus'', which were two genera of mosasaurs, large marine reptiles dating to the Upper Cretaceous (Campanian-Maastrichtian The Maastrichtian ( ) is, in the International Commission on Stratigraphy (ICS) geologic timescale, the latest age (geology), age (uppermost stage (stratigraphy), stage) of the Late Cretaceous epoch (geology), Epoch or Upper Cretaceous series (s ...).

Norwich Crag Formation
The Norwich Crag Formation is a stratigraphic unit of the British Pleistocene Epoch. It is the second youngest unit of the Crag Group, a sequence of four geological formations spanning the Pliocene to Lower Pleistocene transition in East Anglia. It was deposited between approximately 2.4 and 1.8 million years ago, during the Gelasian Stage. The Norwich Crag is a marginal facies of the thicker, much better developed sedimentary sequence in the southern North Sea basin. It outcrops in the eastern half of the counties of Norfolk and Suffolk, and is also represented in Essex and Hertfordshire. It was deposited in a near-shore environment, and comprises a range of sands, silty clays and flint-rich gravels representing various Marine transgression, transgressive and Marine regression, regressive marine episodes. It rests in some places on the Red Crag Formation and in others unconformably on Coralline Crag Formation, Coralline Crag, Palaeogene formations and Chalk Group bedrock. It is ...
