The Chipping Norton Limestone is a geological formation in the Cotswolds, England. It preserves fossils dating back to the Bathonian (Middle Jurassic). Including those of dinosaurs Cetiosaurus, Megalosaurus and Cruxicheiros as well as the Tritylodontid Stereognathus. It primarily consists of ooidal limestone.
Fossil content
The so-called "Scrotum humanum" remains may have come from this formation.
