Semionotiformes
Semionotiformes is an order of primitive, ray-finned, primarily freshwater fish from the Middle Triassic (Anisian) to the Late Cretaceous (Maastrichtian). The best-known genus is ''Semionotus'' of Europe and North America. Their closest living relatives are gars (Lepisosteidae), with both groups belonging to the clade Ginglymodi within the Holostei.

Ginglymodi
Ginglymodi is a clade of ray-finned fish containing modern-day gars (Lepisosteidae) and their extinct relatives, including the family Lepidotidae and the orders Semionotiformes and Kyphosichthyiformes, and various other extinct taxa. Ginglymodi is one of the two major subgroups of the infraclass Holostei, the other one being Halecomorphi, which contains the bowfin and its fossil relatives. Fossil record The fossil record of ginglymodians goes back at least to the Anisian stage of the Triassic period, over 240 million years ago. '' Eosemionotus'' is one of the earliest ginglymodians. '' Acentrophorus'', another taxon from the Wuchiapingian stage of the late Permian, and '' Paracentrophorus'' from the Early Triassic epoch, could be even earlier members of the group. Ginglymodi was diverse and widespread during the Mesozoic era, but they represent a depauperate lineage today. The group first evolved in marine environments, but several lineages made separate transitions into fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holostei
Holostei is a group of ray-finned bony fish. It is divided into two major clades, the Halecomorphi, represented by a single living species, the bowfin (''Amia calva''), as well as the Ginglymodi, the sole living representatives being the gars (Lepisosteidae), represented by seven living species in two genera (''Atractosteus'', ''Lepisosteus''). The earliest members of the clade appeared during the Early Triassic, over 250 million years ago. Holostei was thought to be regarded as paraphyletic. However, a recent study provided evidence that the Holostei are the closest living relates of the Teleostei, both within the Neopterygii. This was found from the morphology of the Holostei, for example presence of a paired vomer. Holosteans are closer to teleosts than are the chondrosteans, the other group intermediate between teleosts and cartilaginous fish, which are regarded as (at the nearest) a sister group to the Neopterigii. The spiracles of holosteans are reduced to vestigial remnan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Luoxiongichthys
''Luoxiongichthys'' is an extinct genus of basal actinopterygian (ray-finned fish) known from the lower Middle Triassic (Pelsonian substage, Anisian stage) of Luoxiong Town, Luoping County of Yunnan Province, southwestern China. It is known from the holotype LPV-10144, which consists of nearly complete skeleton and skull, from the paratype LPV-10120, a partial skull and from the referred materials LPV-10625, LPV-6868 and LPV-11817. It was found in the new Middle Triassic Lagerstätte of the Guanling Formation, Member II. It was first named by Wen Wen, Qi-Yue Zhang, Chang-Yong Zhou, Jin-Yuan Huang, Zhong Qiang Chen and Michael J. Benton in 2011 and the type species is ''Luoxiongichthys hyperdorsalis''. The generic name is derived from ''Luoxiong'' Town, where the specimens were found and ''ichthys'', "fish" from Greek. The specific name comes from ''hyper'', "over" and ''dorsalis'', "of the back" from Greek in reference to its elevated "hump" in front of the dorsal fin. Phyloge ...
