Libys
''Libys'' is a genus of coelacanth lobe-finned fish in the family of Latimeridae. Species of ''Libys'' lived during the Upper Jurassic period (Kimmeridgian - Tithonian, about 150 to 145 million years ago). Description ''Libys'' had an exceptionally squat body, especially when compared to other coelacanths of the same period as '' Undina'' and ''Holophagus''. ''Libys'' could reach 60 centimeters in length and was therefore a medium-sized coelacanth, with a short and high skull. The pectoral fins were quite long, while the tail was remarkably short and high Distribution Fossils of these fishes have been found in Germany Germany,, officially the Federal Republic of Germany, is a country in Central Europe.

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, inhabited both freshwater and marine habitats, and contained some very large species. Together, both comprise the suborder Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinistia
The coelacanths ( ) are fish belonging to the order Actinistia that includes two extant species in the genus ''Latimeria'': the West Indian Ocean coelacanth (''Latimeria chalumnae''), primarily found near the Comoro Islands off the east coast of Africa, and the Indonesian coelacanth (''Latimeria menadoensis''). The name "coelacanth" originates from the Permian genus ''Coelacanthus'', which was the first scientifically named coelacanth. Coelacanths follow the oldest-known living lineage of Sarcopterygii (lobe-finned fish and tetrapods), which means they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish. They are found along the coastline of Indonesia and in the Indian Ocean. The West Indian Ocean coelacanth is a critically endangered species. The oldest known coelacanth fossils are over 410 million years old. Coelacanths were thought to have become extinct in the Late Cretaceous, around 66 milli ...

Jurassic
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 Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era 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. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prehistoric Lobe-finned Fish Genera
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] |
