Crassigyrinus was an amphibian from the early Carboniferous period of Scotland. Prehistoric amphibian Amphibians (class Amphibia such as Frogs Toads Salamanders Newts Gymnophiona, Sirens and The Carboniferous is a geologic period and system that extends from the end of the Devonian period about 359 Scotland ( Gaelic: Alba) is a Country in northwest Europethat occupies the northern third of the island of Great Britain. It is known from two specimens. The complete one is only missing its tail, which was probably long for better swimming. Crassigyrinus had small, very weak limbs that were virtually useless, therefore, this amphibian was almost completely aquatic. Some scientists regard Crassigyrinus as a reptiliomorph. Reptiliomorpha is a name given either to Reptile -like tetrapods or to Amniotes and those Tetrapods related to them Crassigyrinus had unusually large jaws, and ate any other animal it could catch and swallow. It had two rows of sharp teeth in its jaws, the second row having a pair of fangs. Crassigyrinus had large eyes, suggesting that it was either nocturnal, or lived in very murky water. It possessed large otic (spiracular) notches, probably accommodating a spiracle rather than a tympanic membrane[1]
