Coelacanthidae
Coelacanthidae is an extinct family of coelacanths found in freshwater and marine strata throughout the world, originating during the Permian, and finally dying out during the Jurassic. The modern-day genus '' Latimeria'' is often erroneously thought to be in this family, when, in fact, it is the type genus of the more advanced family Latimeriidae, which appeared some time during the 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.

Coelacanth Families
Coelacanths ( ) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. As sarcopterygians, they are more closely related to lungfish and tetrapods (the terrestrial vertebrates including living amphibians, reptiles, birds and mammals) than to ray-finned fish. The name coelacanth originates from the Permian genus '' Coelacanthus'', which was the first scientifically named genus of coelacanths (in 1839), becoming the type genus of Coelacanthiformes as other species were discovered and named. Well-represented in freshwater and marine deposits from as early as the Devonian period (more than 410million years ago), they were thought to have become extinct in the Late Cretaceous, around 66million years ago. The first living species, ''Latimeria chalumnae'', the West Indian Ocean coelacanth, was described from specimens fished off the coast of South Africa from 1938 onward; they are now also known to inhabit the seas around the Comoro Islands off the eas ...

Coelacanthus
''Coelacanthus'', from Ancient Greek κοῖλος (''koîlos''), meaning "hollow", and ἄκανθα (''ákantha''), meaning "spine", is a genus of extinct marine coelacanths known from the late Permian period (geology), period. It was the first genus of coelacanths described, about a century before the discovery of the extant taxon, extant coelacanth ''Latimeria''. The order (biology), order Coelacanthiformes is named after it. Taxonomy The only definitive species in this genus is ''C. granulatus'' from the Lopingian, late Permian (Wuchiapingian stage) Kupferschiefer of Germany and equivalent Marl Slate of England. The genus has long been used to group unrelated species of coelacanths, and several other species that were first referred to ''Coelacanthus'' were later reallocated to other genera. ''Coelacanthus minor'' was considered by Woodward (1891) as potentially belonging to the Triassic genus ''Heptanema'', while Martin and Wenz (1984) considered ''Coelacanthus lunzensis' ...

''Moenkopia'' (meaning "for Moenkopi") is an extinct genus of prehistoric sarcopterygians from the Coelacanthidae found in the Middle Triassic Moenkopi Formation of Arizona.

Latimeriidae
Latimeriidae is the only extant family of coelacanths, an ancient lineage of lobe-finned fish. It contains two extant species in the genus ''Latimeria'', found in deep waters off the coasts of southern Africa and east-central Indonesia. In addition, several fossil genera are known from the Mesozoic of Europe, the Middle East, and the southeastern United States, dating back to the Triassic. The latimeriids are thought to have always been an exclusively marine group. They may have originated in the western Tethys Sea, as many of the earliest species are known from areas that it formerly covered. The largest known member of the family, the Late Cretaceous '' Megalocoelacanthus'', may have reached 4.5 metres in length. The Latimeriidae are thought to be the sister group to the Mawsoniidae, an extinct family of coelacanths that survived until the Late Cretaceous The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in t ...

Jurassic Extinctions
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), 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, Mesozoic Era as well as the eighth period of the Phanerozoic, 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, 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 Anoxic event, oceanic anoxia, ocean acidification, and elevated global temperatures associated with extinctions, likely caused by the eruption of the Kar ...

Triassic Bony Fish
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 chief te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
