Marnes Rouges Inferieures Formation
The Marnes Rouges Inferieures Formation is a Late Cretaceous geologic formation found in the French Pyrenees. It predominantly consists of red mustone, with minor brown mudstone and sandstone.[1] Dinosaurs, dinosaur eggs and avialian stem-birds have been reported from the formation.[2]

gollark: So yes, it's "you can't define a total ordering which works sensibly with other stuff", not "it is literally impossible for you to come up with some stupid one".
gollark: For example, "lexicographic sorting of the complex number represented as a string a+bi".
gollark: Well, I can come up with orderings, just really stupid ones.
gollark: As in, I literally cannot come up with a definition which works, or there's not one which is consistent with other maths?
gollark: Time to define a total order on complex numbers!
