The Saltwick Formation is a Middle Jurassic geologic formation in Yorkshire and the western North Sea. It is primarily Aalenian in age. Fossil footprints, assigned to the tetrapod ichnogenus Characichnos , as well as stegosaur tracks have been reported from the formation. ^{[1] [2]} An indeterminate sauropod, nicknamed Alan, has also been reported from the formation. ^[3]
