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 ...

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] |

Induan
The Induan is the first age of the Early Triassic epoch in the geologic timescale, or the lowest stage of the Lower Triassic series in chronostratigraphy. It spans the time between 251.902 Ma and Ma (million years ago). The Induan is sometimes divided into the Griesbachian and the Dienerian subages or substages. The Induan is preceded by the Changhsingian (latest Permian) and is followed by the Olenekian. The Induan is roughly coeval with the regional Feixianguanian Stage of China. Geology Stratigraphy The Triassic is the first period of the Mesozoic era. It is subdivided into the Lower, Middle, and Upper Triassic series, which are further subdivided into stages. The Induan is the first stage of the Lower Triassic, from 251.9 million to 251.2 million years ago, spanning the first 700,000 years after the Permian–Triassic extinction event. Stages can be defined globally or regionally. For global stratigraphic correlation, the International Commission on Stratigra ...

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''.
