The Tetrapods Transition to Land

1 The Tetrapods Transition to Land The Old Order (or, "Fish Out Of Water") Fossils of Carboniferous amphibians were relatively well known by the turn of the century, as were their probable piscine (fish-like) ancestors, the Devonian lobe-finned fishes.

The tetrapod limb: A hypothesis on its origin

Phylogeny of tetrapods There is strong support for monophyly of all extant and fossil tetrapods (Panchen and Smithson, '88; Ahlberg and Milner, '94; Carroll, '95; Coates, '96; Janvier, '96; Laurin, '98b), of anmiotes, and of the lissamphibians, i.e., the frogs, salamanders, and gymnophions (Gauthier ...

Early tetrapod evolution

Recent studies have questioned long-accepted hypotheses about the origin of the pentadactyl limb, the phylogeny of tetrapods and the environment in which the first tetrapods lived.

Life on Land

Tetrapods have lost this connection and as a result have a flexible neck region that allow the head to be moved separately from the body. Trunk vertebrae bear the ribs.

Tetrapod phylogeny

More inclusive groups of extant tetrapods, such as Lissamphibia, Amniota and Archosauria, may be less familiar, but they are sufficiently well-known to serve as convenient points of departure.
