Tristichopterids
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.

Edenopteron
''Edenopteron'' is a genus of large tristichopterid fish from the Late Devonian (Famennian) of what is now southeastern Australia. It is known from a single specimen of a single species, ''E. keithcrooki'', described in 2013. Discovery ''Edenopteron keithcrooki'' is known from remains excavated from the Worange Point Formation, near the town of Eden on the coast of New South Wales in 2008. The species name is a combination of the name Eden and ''pteron'', meaning wing or fin in Greek. The specific name honors Dr. Keith Crook of the Australian National University for his discovery of several fossil sites in New South Wales and his key role in helping to map the geology around Eden. Description The holotype consists of numerous semi-articulated remains, including an incomplete skull roof, snout, palate, cheeks, lower jaws and associated dermal bones, a left shoulder girdle, and assorted scales. Reconstructions suggest a skull length of 30 cm (12 in) and lower jaw le ... [...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] |

Mandageria
''Mandageria fairfaxi'' (Pronunciation: Man-daj-ee-ree-a fair-fax-i) is an extinct lobe-finned fish that lived during the Late Devonian period (Frasnian – Famennian). It is related to the much larger ''Hyneria''; although ''Mandageria'' was smaller, it probably hunted in the same way. The generic epithet, ''Mandageria'', refers to the Mandagery Sandstone, outcropping near Canowindra, Australia, where the fossils were found. The specific epithet, ''fairfaxi'', honors the philanthropist James Fairfax. ''M. fairfaxi'' is the state fossil emblem for New South Wales. Description ''Mandageria'' was a large predator about long. It had a long torpedo-shaped body and large tail fins. ''Mandageria'' also had large pectoral fins which could have helped it manoeuvre around submerged logs when preparing to attack its prey. ''Mandageria'' had a functional neck joint, an otherwise uncommon feature among fish - ''Tiktaalik'', '' Tarrasius'', placoderms (esp. Arthrodira) and seahorses A ...

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.
