Tristichopterid
Tristichopterids (Tristichopteridae) were a diverse and successful group of tetrapodomorph fishes living throughout the Middle and Late Devonian. They first appeared in the Eifelian stage of the Middle Devonian. Within the group sizes ranged from a few tens of centimeters (''Tristichopterus'') to several meters (''Hyneria'' and ''Eusthenodon''). Some tristichopterids share some of the features of the elpistostegalians, a diverse clade of fishes close to the origin of (and including) tetrapods. This mainly concerns the shape of the skull and a reduction in size of the posterior fins. An old and persistent notion is that ''Eusthenopteron'' was able to crawl onto land using its fins. However, there is no evidence actually supporting this idea.M. Laurin, F. J. Meunier, D. Germain, and M.

Eusthenodon
''Eusthenodon'' (Greek for “strong-tooth” – ''eustheno''- meaning “strength”, -''odon'' meaning “tooth”) is an extinct genus of tristichopterid tetrapodomorphs from the Devonian, Late Devonian period, ranging between 383 and 359 million years ago (Frasnian to Famennian). They are well known for being a cosmopolitan genus with remains being recovered from East Greenland, Australia, Central Russia, South Africa, Pennsylvania, and Belgium. Compared to the other closely related genera of the Tristichopteridae clade, ''Eusthenodon'' was one of the largest Sarcopterygii, lobe-finned fishes (approximately 2.5 meters in length) and among the most derived tristichopterids alongside its close relatives ''Cabonnichthys'' and ''Mandageria''. The large size, predatory ecology, and evolutionarily derived characters possessed by ''Eusthenodon'' likely contributed to its ability to occupy and flourish in the numerous localities across the world mentioned above.

Osteolepiformes
Osteolepiformes, also known as Osteolepidida, is a group of prehistoric lobe-finned fishes which first appeared during the Devonian period. The order contains the families Canowindridae, Megalichthyidae, Osteolepididae and Tristichopteridae. The order is generally considered to be paraphyletic because the characters that define it are mainly attributes of stem tetrapodomorphs. Below is a cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms.

Tetrapodomorphs
The Tetrapodomorpha (also known as Choanata) are a clade of vertebrates consisting of tetrapods (four-limbed vertebrates) and their closest sarcopterygian relatives that are more closely related to living tetrapods than to living lungfish. Advanced forms transitional between fish and the early labyrinthodonts, such as ''Tiktaalik'', have been referred to as "fishapods" by their discoverers, being half-fish, half-tetrapods, in appearance and limb morphology. The Tetrapodomorpha contains the crown group tetrapods (the last common ancestor of living tetrapods and all of its descendants) and several groups of early stem tetrapods, which includes several groups of related lobe-finned fishes, collectively known as the osteolepiforms. The Tetrapodamorpha minus the crown group Tetrapoda are the Stem Tetrapoda, a paraphyletic unit encompassing the fish to tetrapod transition. Among the characteristics defining tetrapodomorphs are modifications to the fins, notably a humerus with convex he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyneria
''Hyneria'' is a genus of large prehistoric predatory lobe-finned fish which lived in freshwater during the Devonian period around 360 million years ago. Etymology The genus name ''Hyneria'' is a reference to the village of Hyner, Pennsylvania, near where the first specimen was found. The species epiphet ''H. lindae'' is derived from the name of the wife of Keith Stewart Thomson, who described this fish. Description ''Hyneria'' was a large fish, with discovered remains estimated between in total length. Its skull had heavy, ornamented dermal bones and its lower jaw was relatively long and shallow. The teeth were stout with those of the premaxilla forming fangs upwards of . Its body was covered by cycloid scales. It had large sensory canals to aid in detection of possible prey, as the freshwater environment it inhabited likely was murky and had low visibility. Adult individuals retained the juvenile features (i.e. partially unossified skeletons), suggesting that they were likel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
