Labyrinthodontia Greek , 'maze-toothed' is an extinct amphibian subclass, which constituted some of the dominant animals of late Paleozoic and early Mesozoic eras about to million years ago. The group evolved from lobe-finned fishes in the Devonian and is ancestral to all extant landliving vertebrates. The name describes the pattern of infolding of the dentin and enamel of the teeth, which are often the only part of the creatures that fossilize. They are also distinguished by a heavily armoured skull roof hence the older name " Stegocephalia " , and complex vertebrae, the structure of which were used in older classifications of the group. Because labyrinthodonts do not form a monophyletic group, many modern researchers have abandoned the term.
