	Labyrinthodontia - Wikipedia, the free encyclopedia
		Labyrinthodont (Greek, "maze-toothed") is an obsolete term for any member of an extinct superorder or subclass (Labyrinthodontia) of amphibians, which constituted some of the dominant animals of Late Paleozoic and Early Mesozoic times (about 350 to 210 million years ago).
		The name describes the pattern of infolding of the dentine and enamel of the teeth, which are often all of the creatures that survives.
		The groups that have usually been placed within Labyrinthodontia, are currently variously classified as basal tetrapods, non-amniote Reptiliomorpha and as a monophyletic or paraphyletic Temnospondyli, according to cladistic analysis.

	Amphibian - Wikipedia, the free encyclopedia
		With the cladistic revolution, this classification has been modified, and the Labyrinthodontia discarded as being a paraphyletic group without unique defining features apart from shared primitive characteristics.
		Generally amphibians are defined as the group that includes the common ancestors of all living amphibians (frogs, salamanders, etc) and all their descendants.
		This means that there are a now large number of basal Devonian and Carboniferous tetrapod groups, described as "amphibians" of earlier books, that are no longer placed in the formal Amphibia.

		A Labyrinthodont (Greek, "maze-toothed") is any member of an extinct superorder or subclass (Labyrinthodontia) of amphibians, which constituted some of the dominant animals of Late Paleozoic and Early Mesozoic times (about 350 to 210 million years ago).
		Labyrinthodontia Diagnostic features unique to the Labyrinthodontia are hard to find at first glance; the complex dentine infolding tooth structure was shared with crossopterygian fish.
		The Labyrinthodontia had a peculiar tooth structure from which their name was derived and, although not exculsive to the group, the labyrinthine dentition is a useful indicator as to proper classification.

	Classification & Natural History of Amphibians
		All those little squiggley lines are there as to sort of graphically communicate to you thatthis group of animals, the labyrinthodontia which are represented by those names and lines, was avery diverse group.
		And the other piece of evidence that's sort of presented graphically here is that the lines ofevolution that gave rise to the 3 living groups of amphibians, the frogs, a group of animals thatyou probably haven't heard of that are the limbless types, and the salamanders.
		And the name "labyrinthodontia" is a reference to the structure of their teeth which, is afairly peculiar tooth structure.

	Archegosaurus decheni
		The Crossotterigi ripidisti, which the Labyrinthodontia evolved from, lived during the Devonian in fresh water pools that dotted the arid continental plains.
		Some palaeontologists believe that because the Devonian was characterised by dry periods and spells of torrential rain, these water pools dried out periodically.
		The Labyrinthodontia flourished in the Carboniferous period, continued to spread in the Permian and the Triassic periods, and finally became extinct at the end of this geological period.

	Amphibians
		The amphibians of the Labyrinthodontia, which lived during the late Devonian through Triassic periods (345 to 190 million years ago), include the most primitive amphibians represented by the genus Ichthyostega.
		The Labyrinthodontia, according to the U.S. paleontologist Alfred S. Romer, include three extinct orders: the Ichthyostegalia, the Temnospondyli, and the Anthracosauria.
		The Anthracosauria are thought to be the ancestors of reptiles and hence of modern birds and mammals.

		These animals were fish-like in that they still had the scale structures seen on the skin of fish.
		Just as the modern amphibians are aquatic in their early life stage, the Labyrinthodontia were also.
		This was discovered through examination of the fossil skulls of juvenile animals of this group.

		Some of the Stegocephala were of very large size, and the form of the body varied from short, stout forms to others that were as slender as serpents.
