Distribution

Fossils of Docidoceras have been found in:[3]

gollark: *What* under UV?
gollark: Although I guess being imprisoned is an arbitrary human construct too.
gollark: Time to become a burglar and steal people's stuff but not get punished because ownership is an arbitrary human construct!
gollark: well, that seems like a weird view if you apply it to physical objects, which constantly change slightly when they interact with their environment.
gollark: Which poses an interesting philosophical question: if you replace all the parts of a bot one by one, is it the same bot afterward?
