Taxonomy

Cochlioceras was named by Eichwald (1860). Its type is Cochlioceras avus. It was assigned to the Baltoceratidae by Furtnish and Glensiter in Teichert et al. (1964) [1] and removed, with the Baltoceratidae, from the Ellesmerocerida to the Orthocerida by Kroger et al. (2007)[2]

gollark: Oh, right.
gollark: Otherwise your turtles will just go and rescan "no block" areas constantly.
gollark: Well, you need to distinguish between them.
gollark: Also, why not store the type of block too?
gollark: I was going to suggest a bitmap or something, but you need *three* states for that - block, no block, unscanned block.
