Yochelcionelloidea is an extinct superfamily of paleozoic molluscs of uncertain position (Gastropoda or Monoplacophora).[1] The earliest yochelcionellids are known from the Middle Tommotian, but they are most diverse from the Botomian through the early Middle Cambrian.[2]

According to the opinion of P. Yu. Parkhaev is in the class Helcionelloida, subclass Archaeobranchia Parkhaev, 2001, Order Helcionelliformes Golikov & Starobogatov, 1975:[3][4]

gollark: Well, there might be, juroku may be able to use tape drives, if you have computronics.

gollark: Also, there would be no sound.

gollark: You need a program called juroku or something, which runs out of game and converts video files (I think?) so they can be displayed in CC. But it's apparently hard to get working, the resolution is obviously not great because CC, and it's not as simple as "run program ingame, search for video, play".

gollark: Technically yes, but I wouldn't recommend it.

gollark: or 381.
