Megalocephalus (meaning "big head") is an extinct genus of baphetid amphibian from the late Carboniferous of the British Isles.[3] It contains two species, M. pachycephalus and M. lineolatus.
Description[]
Megalocephalus was a small amphibian, measuring 1.5 metres (4.9 ft) from head to tail.
Skull[]
It is only known from its skull, like most other baphetids. The skull of Megalocephalus was 30 centimetres (12 in) long. The teeth of Megalocephalus were long and pointed. Baphetids had a small elongation of their eye sockets, of which the current use for is not certain. It has been suggested that the elongation was housing for a salt gland to get rid of excess salt, or a extra region for jaw muscle attachments, to allow a harder bite force.
