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.

Jacobulus
''Jacobulus'' is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch in what is now northern Madagascar 252.3 to 251.3 million years ago. The type species is ''Jacobulus novus'' (monotypy). It was a small fish less than in length. J. novus ecology was a grazer-detritivore.

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''.

Parasemionotus
''Parasemionotus'' is an extinct genus of prehistoric bony fish that lived in the Induan age (geology), age of the Early Triassic epoch in what is now Madagascar. It is the name giving genus of the family (taxonomy), family Parasemionotidae and the order (taxonomy), order Parasemionotiformes. This clade includes, among others, the genera ''Albertonia'', ''Candelarialepis'', ''Jacobulus'', ''Lehmanotus'', ''Qingshania'', ''Stensioonotus, 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 ''Semi ...

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 Stratigraphy (ICS) r ...

Prehistoric Animals Of Madagascar
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Gnathostomata, 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 Placodermi, placoderms, which evolved from the ostracoderms; and the ...
