	Lissamphibia - Wikipedia, the free encyclopedia
		Whilst the monophyly of the Lissamphibia is accepted by many herpetologists and paleontologists, the origin and relationships of the various Lissamphibian groups both with each other and among other early tetrapods remains controversial.
		Not all paleontologists are convinced that the lissamphibia are indeed a natural group, as the various characteristics are also shared with some Paleozoic amphibians, and it is still possible that these characteristics evolved independently.
		Currently there are three prevailing theories of Lissamphibian origin: monophyletic within the temnospondyli, monophyletic within lepospondyli, and diphyletic (two separate ancestries) with apodans within the lepospondyls and salamanders and frogs within the temnospondyli.

		But these amphibians that are placed in the subclass Lissamphibia have a -- don't havea continuous tooth, they have a plane of fibrous connective tissue that separates the tooth itselffrom this little bony foundation piece that's down in the jaw.
		The term "Lissamphibia" is reference to the fact that they have smooth skin.
		The reason that these guys have smooth skin, and that is that they have lost the scales thattheir Labyrinthodonts ancestors must have had, is that they all exchange some significant amountsof oxygen through the skin.

	Early Land Vertebrates
		Cowen (2000) states that the Temnospondyls were "the largest and most diverse group of early" tetrapods or "amphibians" (40 families and 160 genera), and they seem to be the group from which some or all modern amphibians (Lissamphibia -- frogs and salamanders) evolved in the late Paleozoic or Triassic.
		The fossil record for modern amphibians (Lissamphibia) begins in the Jurassic, which is later than that for mammals and dinosaurs.

		There are considered to be three orders of amphibians or Amphibia which have been placed in the subclass Lissamphibia.
		These three groups are associated in the Lissamphibia by characteristics of tooth, skin, and fat body structure.
		Vertebral and skull structure, as well as other characteristics, differ considerably among the three groups.
