Rutland Formation
The Rutland Formation is a geologic formation in England. It preserves fossils dating back to the late Bajocian to Bathonian stages in the Jurassic period, about 169 million years ago. It is the lateral equivalent of the Sharp's Hill Formation and the Fuller's Earth Formation. The "Rutland Dinosaur" specimen of Cetiosaurus is known from the formation.[1]
