Synonyms

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.
