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]

gollark: Which "movie" is this?

gollark: London's underground train system.

gollark: I got C3. D2 might be valid but I'm not sure.

gollark: How do you know you're right about that being the best path then?

gollark: How did you work that out? Spending unreasonable amounts of effort to put it into a computery program?
