Parasemionotidae
Parasemionotiformes is an extinct order of neopterygian ray-finned fish that existed globally during the Triassic period. It comprises the families Parasemionotidae and Promecosominidae. Many of the included genera are monotypic and most species lived during the Early Triassic epoch.Romano et al. (2016): Marine Early Triassic Osteichthyes from Spiti, Indian Himalayas. Swiss Journal of Palaeontology 135: 275-294 https://doi.org/10.1007/s13358-015-0098-6 Parasemionotiforms were normally small to medium-sized fishes. They were predominantly marine. Evolutionary relationships Parasemionotiformes are neopterygians, which is the clade that encompasses the vast majority of living ray-finned fishes (Actinopterygii) and about half of all living species of vertebrates. Neopterygii are divided into Teleostei and Holostei. The latter represents a depauperate group today but used to be a diverse clade especially during the Mesozoic Era. The only surviving members of the Holostei are the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parasemionotus
''Parasemionotus'' is an extinct genus of prehistoric bony fish that lived in the Induan age of the Early Triassic epoch in what is now Madagascar. It is the name giving genus of the family Parasemionotidae and the order Parasemionotiformes. This clade includes, among others, the genera '' Albertonia'', ''Candelarialepis'', ''Jacobulus'', ''Lehmanotus'', '' Qingshania'', '' Stensioenotus'', '' Suius'', ''Thomasinotus'', ''Watsonulus'', and possibly additional genera like '' Promecosomina''. Parasemionotiforms had a global distribution during the Early Triassic. Species of this family are found in Greenland, Madagascar, Canada, India, China, United States, and possibly Australia. The type species ''Parasemionotus labordei'' was first described under the name ''Semionotus labordei'' by Ferdinand Priem. Jean Piveteau later erected the new genus name ''Parasemionotus'' for this species. It is not closely related with ''Semionotus''. See also * Prehistoric fish * List o ...

Watsonulus
''Watsonulus'' is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch in what is now Madagascar. It may have also existed in what is now Himachal Pradesh, India, during the Induan age (Early Triassic).Romano et al. (2016): Marine Early Triassic Osteichthyes from Spiti, Indian Himalayas. Swiss Journal of Palaeontology 135: 275-294 https://doi.org/10.1007/s13358-015-0098-6 The type species, described by Jean Piveteau, is ''Watsonia eugnathoides''. Because "''Watsonia''" was preoccupied, the new genus name ''Watsonulus'' was later erected. Classification ''Watsonulus'' belongs to Parasemionotidae, a family of early neopterygians closely related with halecomorphs. Other members of Parasemionotidae include '' Albertonia'', '' Candelarialepis'', '' Icarealcyon'', ''Jacobulus'', ''Lehmanotus'', ''Parasemionotus'', '' Qingshania'', '' Stensioenotus'', '' Suius'', and ''Thomasinotus''.

Prehistoric Fish
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include '' Haikouichthys''. During the late Cambrian, eel-like jawless fish called the conodonts, and small mostly armoured fish known as ostracoderms, first appeared. Most jawless fish are now extinct; but the extant lampreys may approximate ancient pre-jawed fish. Lampreys belong to the Cyclostomata, which includes the extant hagfish, and this group may have split early on from other agnathans. The earliest jawed vertebrates probably developed during the late Ordovician period. They are first represented in the fossil record from the Silurian by two groups of fish: the armoured fish known as placoderms, which evolved from the ostracoderms; and the Acanthodii (or s ...

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic ...
