Dutuitosaurus
''Dutuitosaurus'' is a genus of metoposaurids, a group of amphibians that lived during the Late Triassic period. ''Dutuitosaurus'' was discovered in the early 1960s in Morocco and is known from the lower t5 units of the Timezgadiouine Formation exposures in the Argana Basin of the High Atlas Mountains and was first described in 1976 by French paleontologist Jean-Michel Dutuit. Material of ''Dutuitosaurus'' is currently held in the Muséum national d'histoire naturelle (MNHN) in Paris, France. It was originally placed within '' Metoposaurus'' as ''M. ouazzoui'' but was subsequently placed in its own genus, ''Dutuitosaurus'', by Hunt (1993), who identified a number of differences between ''Metoposaurus'' (classically a European genus) and the Moroccan metoposaurids. Features that differentiate ''Dutuitosaurus'' from other metoposaurids include relative elongate intercentra and a maxilla that enters the orbit. Although many metoposaurids are known from so-called mass death assembla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Timezgadiouine Formation
The Timezgadiouine Formation, sometimes spelled as the Timesgadiouine Formation, is a Triassic geological formation in the Argana Basin of Morocco. It is a succession of red bed sediments spanning from the Olenekian to at least the Carnian, encompassing members T3 to T5 of the Argana Group. It is preceded by the Permian Ikakern Formation and succeeded by the Late Triassic Bigoudine Formation. The formation is split into three members. The Early Triassic Tanamert Member (T3) is a relatively thin band of volcaniclastic conglomerate, likely emplaced by braided rivers. The Middle Triassic Aglegal Member (T4) is a thick sequence of muddy and silty cyclical deposits interspersed with wide sandstone lenses. It would have been deposited within a semi-arid playa, mudflat, and ephemeral lake system cut by meandering streams or sheet floods. The late Carnian (or possibly early Norian) Irohalene Member (T5) comprises bioturbated mudstone complemented by an increasing abundance of sandstone ...

Metoposaurus
''Metoposaurus'' meaning "front lizard" is an extinct genus of stereospondyl temnospondyl amphibian, known from the Late Triassic of Germany, Italy, Poland, and Portugal. https://www.app.pan.pl/archive/published/app47/app47-535.pdf This mostly aquatic animal possessed small, weak limbs, sharp teeth, and a large, flat head. This highly flattened creature mainly fed on fish, which it captured with its wide jaws lined with needle-like teeth. ''Metoposaurus'' was up to 3 m (10 feet) long and weighed about 450 kg (1,000 pounds). Many ''Metoposaurus'' mass graves have been found, probably from creatures that grouped together in drying pools during drought. Discovery and species Discovery The earliest mention of Metoposauridae dates back to 1842 when Von Meyer described the dorsal view of the skull roof of a labyrinthodont from the Keuper Schilfsandstein of Feuerbacher Haide near Stuttgart. Later, Meyer attempted a reconstruction of the same specimen and named it ''Metopias ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metoposauridae
Metoposauridae is an extinct family of trematosaurian temnospondyls. The family is known from the Triassic period. Most members are large, approximately long and could reach 3 m long.Brusatte, S. L., Butler R. J., Mateus O., & Steyer S. J. (2015). A new species of Metoposaurus from the Late Triassic of Portugal and comments on the systematics and biogeography of metoposaurid temnospondyls. Journal of Vertebrate Paleontology. e912988., 2015: Metoposaurids can be distinguished from the very similar mastodonsauroids by the position of their eyes, placed far forward on the snout. Taphonomy Several mass accumulations of metoposaurid fossils are known from the southwestern United States and Morocco. These have often been interpreted as the result of mass deaths from droughts. Many individuals would have died in one area, creating a dense bone bed once fossilized. These mass accumulations of metoposaurids are often dominated by one taxa, such as '' Anaschisma'' or '' Metoposaurus''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Amphibian
This list of prehistoric amphibians is an attempt to create a comprehensive listing of all Genus, genera from the fossil record that have ever been considered to be amphibians, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomen dubium, nomina dubia''), or were not formally published (''nomen nudum, nomina nuda''), as well as synonym (zoology), junior synonyms of more established names, and genera that are no longer considered amphibians. Modern forms are excluded from this list. The list currently includes 454 names. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Synonym (zoology), Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type (zoology), type specimens are later assigned to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High Atlas
High Atlas, also called the Grand Atlas ( ar, الأطلس الكبير, Al-Aṭlas al-Kabīr; french: Haut Atlas; shi, ⴰⴷⵔⴰⵔ ⵏ ⴷⵔⵏ ''Adrar n Dern''), is a mountain range in central Morocco, North Africa, the highest part of the Atlas Mountains. The High Atlas rises in the west at the Atlantic Ocean and stretches in an eastern direction to the Moroccan-Algerian border. At the Atlantic and to the southwest the range drops abruptly and makes an impressive transition to the coast and the Anti-Atlas range. To the north, in the direction of Marrakech, the range descends less abruptly. The range includes Jbel Toubkal, which at is the highest in the range and lies in Toubkal National Park. The range serves as a weather system barrier in Morocco running east–west and separating the Sahara from the Mediterranean and continental zones to the north and west. In the higher elevations of the massif, snow falls regularly, allowing winter sports. Snow lasts well into late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas Mountains
The Atlas Mountains are a mountain range in the Maghreb in North Africa. It separates the Sahara Desert from the Mediterranean Sea and the Atlantic Ocean; the name "Atlantic" is derived from the mountain range. It stretches around through Morocco, Algeria and Tunisia. The range's highest peak is Toubkal, which is in central Morocco, with an elevation of . The Atlas mountains are primarily inhabited by Berbers, Berber populations. The terms for 'mountain' are ''Adrar'' and ''adras'' in some Berber languages, and these terms are believed to be cognates of the Toponymy, toponym ''Atlas''. The mountains are also home to a number of animals and plants which are mostly found within Africa but some of which can be found in Europe. Many of these species are endangered and a few are already extinct. The weather is cooling but has sunny summers, and the average temperature there is 25°C.Atlas Mountains are a mountain range in the Maghreb in North Africa. It separates the Sahara Desert fro ...
