Diplocaulidae

The Diplocaulidae ("double cauls") is an extinct family of lepospondyl amphibians that arose during the Late Carboniferous and died out in the Late Permian. [1] They are distinguished from other amphibians, extinct and extant, by the presence of strange, horn-like protrusions jutting out from the rear of their skulls; in some genera said protrusions gave their heads an almost boomerang-like outline.

gollark: Er. What?
gollark: Not infinite mass, I think it's just infinite density.
gollark: Watts are power (energy per time), so I'm pretty sure that question doesn't actually make sense.
gollark: No, still stupid. Yes, you can not know things and that is fine. But not looking up relevant safety information (or ignoring it? If I remember right, that person was not very receptive to people saying that they were doing stupid things) when doing something you can quite easily recognize as potentially dangerous is stupid.
gollark: I would consider mishandling radioactive material, or trolling about it, very stupid.
