Falcatidae
Falcatidae is a family of paleozoic holocephalians.[1] Members of this Family include Falcatus, a small fish from the Bear Gulch Limestone of Montana.[2] The family first appeared around the start of the Carboniferous, and there is some evidence that they survived well into the early Cretaceous.[3]

gollark: No.
gollark: It's an unboxed tuple, whatever.
gollark: Anyway, the IO monad is implemented as a tuple of `(value, the state of all reality)`.
gollark: (The state monad is a burrito which forms governments)
gollark: No, the state monad is cooler.
