Rutland Formation

The Rutland Formation is a geologic formation in England. It preserves fossils dated to the late Bajocian to Bathonian ages of 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]
