Saurorhynchus Anningiae
''Saurorhynchus'' is an extinct genus of carnivorous bony fish that lived during the Early and Middle Jurassic epochs. Fossils have been found in Europe (France, Belgium, Luxembourg, United Kingdom, Germany, Italy) and North America (Canada). It is commonly found in pelagic and lagoonal deposits, but mostly marine. Largest specimens can grow up to . Four Jurassic species are recognized. In addition, the Late Triassic species '' Saurichthys striolatus'', '' Saurichthys calcaratus'', and '' Saurichthys deperditus'' are sometimes referred to ''Saurorhynchus'', although ''Saurorhynchus'' is then treated as a subgenus of ''Saurichthys''. ''Saurorhynchus'' is the youngest representative of the family Saurichthyidae and the order Saurichthyiformes. This family is known for its large, elongate jaws, similar to modern Belonidae. Saurichthyidae also includes the Permian genus ''Eosaurichthys'' and the Triassic genus ''Saurichthys''. See also * Prehistoric fish * List of prehistoric b ...

Sinemurian
In the geologic timescale, the Sinemurian is an age (geology), age and stage (stratigraphy), stage in the Early Jurassic, Early or Lower Jurassic epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between 199.5 ±0.3 annum, Ma and 192.9 ±0.3 Ma (million years ago). The Sinemurian is preceded by the Hettangian and is followed by the Pliensbachian. In Europe the Sinemurian age, together with the Hettangian age, saw the deposition of the lower Lias Group, Lias, in Great Britain known as the Blue Lias. Stratigraphic definitions The Sinemurian Stage was defined and introduced into scientific literature by French palaeontologist Alcide d'Orbigny in 1842. It takes its name from the French town of Semur-en-Auxois, near Dijon. The calcareous soil formed from the Jurassic limestone of the region is in part responsible for the character of the classic Sancerre (wine), Sancerre wines. The base of the Sinemurian Stage is at the first appearance of the ammonite genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saurichthys
''Saurichthys'' (from , 'lizard' and 'fish') is an extinct genus of predatory Actinopterygii, ray-finned fish from the Triassic period (geology), Period. It is the type genus of the family (taxonomy), family Saurichthyidae (Changhsingian-Jurassic, Middle Jurassic), and the most speciose and longest lasting genus in the family. This family also includes the Permian ''Eosaurichthys'' (China) and the Jurassic ''Saurorhynchus'' (= ''Acidorhynchus'') from Europe and North America, though it may be more appropriate to treat these as subgenera of ''Saurichthys,'' due to the genus ''Saurichthys'' otherwise being paraphyletic.'''' Fossils of ''Saurichthys'' have been found on all continents except South America and Antarctica.''Saurichthys'' at Fossilworks.org It inhabited both marine and fres ...

Jurassic Bony Fish
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately 143.1 Mya. The Jurassic constitutes the second and middle period of the Mesozoic Era as well as the eighth period of the Phanerozoic Eon and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province (CAMP). The beginning of the Toarcian Age started around 183 million years ago and is marked by the Toarcian Oceanic Anoxic Event, a global episode of oceanic anoxia, ocean acidification, and elevated global temperatures associated with extinctions, likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear, definitive boundary with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prehistoric Fish
__NOTOC__ Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called ''paleoichthyology''. A few living forms, such as the coelacanth are also referred to as prehistoric fish, or even living fossils, due to their current rarity and similarity to extinct forms. Fish which have become recently extinct are not usually referred to as prehistoric fish. Lists of various prehistoric fishes include: * List of prehistoric jawless fish * List of placoderms * List of acanthodians * List of prehistoric cartilaginous fish *List of prehistoric bony fish This list of prehistoric bony fish is an attempt to create a comprehensive listing of all Genus, genera from the fossil record that have ever been considered to be bony fish (class Osteichthyes), excluding purely vernacular terms.

Triassic
The Triassic ( ; sometimes symbolized 🝈) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.4 Mya. The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eosaurichthys
''Eosaurichthys'' ("dawn ''Saurichthys''") is an extinct genus, or potentially subgenus, of marine saurichthyidae, saurichthyid ray-finned fish that lived during the late Permian epoch (geology), epoch (Changhsingian age) to potentially the Early Triassic epoch (Olenekian). It is one of the earliest saurichthyid genera known from the fossil record. If ''E. madagascariensis'' is a member of this genus, then it appears to have survived the Permian–Triassic extinction event, Permian-Triassic extinction event. ''Eosaurichthys'' is often treated as a subgenus of ''Saurichthys'' rather than a genus, with its type species referred to as ''Saurichthys'' (''Eosaurichthys'') ''chaoi''. Up to two species are known: * ''E. chaoi'' Liu & Wei, 1988 - Lopingian, Late Permian (Changhsingian) of China (Changxing Formation) * ''E. madagascariensis'' (Jean Piveteau, Piveteau, 1945) - Early Triassic (Olenekian) of Madagascar (Sakamena Formation) Saurichthyid remains tentatively referred to ''E. ...

Permian
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belonidae
Needlefish (Family (biology), family Belonidae) or long toms are piscivorous bony fish, fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., ''Strongylura''), while a few genera are confined to freshwater rivers and streams, including ''Belonion'', ''Potamorrhaphis'', and ''Xenentodon''. Needlefish closely resemble North American freshwater gars (family Lepisosteidae) in being elongated and having long, narrow jaws filled with sharp teeth, and some species of needlefishes are referred to as gars or garfish despite being only distantly related to the true gars. In fact, the name "garfish" was originally used for the needlefish ''Belone belone'' in Europe and only later applied to the North American fishes by European settlers during the 18th century. Description Needlefish are slender, ranging from in length. They have a single dorsal fin, placed far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saurichthyiformes
Saurichthyiformes is an extinct order (biology), order of Actinopterygii, ray-finned fish which existed in Asia, Africa, Australia (continent), Australia, Europe and North America, during the late Permian to early Middle Jurassic. Saurichthyiiformes comprise two families, Saurichthyidae and Yelangichthyidae. Yelangichthyidae is monotypy, monotypic, containing only the genus ''Yelangichthys.'' The gar or needlefish-like Saurichthyidae is primarily known from the genus ''Saurichthys.'' Additionally, the subgenus, subgenera ''Saurorhynchus'' ''Costasaurichthys'', ''Eosaurichthys'', ''Lepidosaurichthys'', and ''Sinosaurichthys'' are frequently used to group species, and are sometimes considered separate genera. Species are known from both marine end freshwater deposits. They had their highest diversity during the Early Triassic, Early and Middle Triassic. Their phylogenetic position is uncertain, while they have often been considered members of Chondrostei, and thus related to liv ...
