The Scunthorpe Mudstone is a geologic formation in England. It preserves plesiosaur fossils dating back to the Late Triassic ( Rhaetian) to Early Jurassic ( Hettangian) period. [1] It predominantly consists of grey mudstone with thin beds of argillaceous limestone and calcareous siltstone. [2] The Ichthyosaur Wahlisaurus is known from the formation. [3] As is the holotype specimen of the dinosaur Sarcosaurus. [4]
