Machimosauridae
Machimosauridae is an extinct family of teleosauroid thalattosuchian crocodyliforms. Text was copied from this source, which is available under Creative Commons Attribution 4.0 International License The family was first identified in 2016, when fossils of teleosauroid thalattosuchians, including an indeterminate close relative of '' Lemmysuchus'' and ''Machimosaurus'', were described from the Middle Jurassic (Bathonian) of Morocco. The family was largely expanded in 2020 when the systematics of Teleosauroidea were re-reviewed. Members of this family generally were larger than the teleosaurids. Classification Machimosauridae is a diverse group of teleosauroids, phylogenetically defined as "the largest clade within Teleosauroidea containing '' Machimosaurus hugii'', but not ''Plagiophthalmosuchus gracilirostris'' and '' Teleosaurus cadomensis''." The members of the Machimosauridae share several unique characters among teleosauroids, which are: * dorsally oriented external ...

Clovesuurdameredeor Stephani
''Clovesuurdameredeor'' (meaning "sea creature of Closworth"; from the Medieval Latin ''Clovesuurda'' and the Old English ''meredeor'') is an extinct genus of machimosaurid teleosauroid from the Bathonian Cornbrash Formation of England. The type species, ''C. stephani'', was originally named "''Steneosaurus''" ''stephani'' by Hulke in 1867. Vignaud (1995) considered ''S. stephani'' to be a minor synonym of '' Yvridiosuchus boutilieri'' (then still in the genus ''Steneosaurus ''Steneosaurus'' (from el, στενός , 'narrow' and el, σαῦρος , 'lizard') is a dubious genus of teleosaurid crocodyliform from the Middle or Late Jurassic (Callovian or early Oxfordian) of France.

Proexochokefalos
''Proexochokefalos'' (meaning "big head with big tuberosities") is an extinct genus of machimosaurid teleosauroid from the Jurassic of France Classification The type species, ''S. heberti'', was originally named "''Steneosaurus''" ''heberti'' by Morel de Glasville in 1876 from a complete skull and mandible (MNHN.F ) found in the Callovian aged Marnes de Dives near Villers-sur-mer in the Calvados department of Normandy, France.

Charitomenosuchus
''Charitomenosuchus'' (meaning "graceful crocodile") is an extinct genus of machimosaurid teleosauroid from the Callovian Oxford Clay Formation of England England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe .... The type species, ''C. leedsi'', was originally named "''Steneosaurus''" ''leedsi'' by Andrews in 1909 on the basis of three specimens. In her unpublished 2019 thesis, Michela Johnson coined the nomen ex dissertationae ''Charitomenosuchus'' for ''S. leedsi''. The genus name was published in 2020.

Morocco
Morocco (),, ) officially the Kingdom of Morocco, is the westernmost country in the Maghreb region of North Africa. It overlooks the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria to the east, and the disputed territory of Western Sahara to the south. Mauritania lies to the south of Western Sahara. Morocco also claims the Spanish exclaves of Ceuta, Melilla and Peñón de Vélez de la Gomera, and several small Spanish-controlled islands off its coast. It spans an area of or , with a population of roughly 37 million. Its official and predominant religion is Islam, and the official languages are Arabic and Berber; the Moroccan dialect of Arabic and French are also widely spoken. Moroccan identity and culture is a mix of Arab, Berber, and European cultures. Its capital is Rabat, while its largest city is Casablanca. In a region inhabited since the Paleolithic Era over 300,000 years ago, the first Moroccan st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machimosaurus Hugii
''Machimosaurus'' is an extinct genus of machimosaurid crocodyliform from the Late Jurassic (Kimmeridgian and Tithonian) and Early Cretaceous. The type species, ''Machimosaurus hugii'', was found in Switzerland. Other fossils have been found in England, France, Germany, Portugal, Switzerland and Tunisia.Steel R. 1973. ''Crocodylia.

''Machimosaurus'' is the largest known crocodyliform of the Jurassic. Discovery and species Christian Erich Hermann von Meyer in 1837 named isolated conical, blunt teeth with numerous longitudinal lines from Switzerland, ''Madrimosaurus hugii''. However, in 1838, realising he had misspelled the name, he emended ''Madrimosaurus'' to ''Machimosaurus'', from the Greek ''machimoi'', ancient Egyptian troops deployed during the Ptolemaic Dynas ...

Teleosaurus Cadomensis
''Teleosaurus'' (from el, τέλειος , 'perfect' and el, σαῦρος , 'lizard') is an extinct genus of teleosaurid crocodyliform found in the Middle Jurassic Calcaire de Caen Formation of France. It was approximately in length and weighed . The holotype is MNHN AC 8746, a quarter of a skull and other associated postcranial remains, while other fragmentary specimens are known. The type species is ''T. cadomensis'', but a second species, ''T. geoffroyi'' may also exist. It was previously considered a wastebasket taxon, with many other remains assigned to the genus. History Teleosaur remains have been known to science since at least 1758, although at first scientists believed the remains belonged to extinct crocodiles and alligators, and remains that have at one point in time been attributed to ''Teleosaurus'' (and ''Steneosaurus'') have been known to science since at least 1800.

Premaxilla
The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth. In humans, they are fused with the maxilla. The "premaxilla" of therian mammal has been usually termed as the incisive bone. Other terms used for this structure include premaxillary bone or ''os premaxillare'', intermaxillary bone or ''os intermaxillare'', and Goethe's bone. Human anatomy In human anatomy, the premaxilla is referred to as the incisive bone (') and is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a bony plate with a generally transverse orientation. The incisive foramen is bound anteriorly and laterally by the premaxilla and posteriorly by the palatine process of the maxilla. It is formed from ...

Ventrally
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatomy ...

Middle Jurassic
The Middle Jurassic is the second epoch of the Jurassic Period. It lasted from about 174.1 to 163.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Daohugou Beds in China, the Itat Formation in Russia, and the Isalo III Formation of western Madagascar. Paleogeography During the Middle Jurassic Epoch, Pangaea began to separate into Laurasia and Gondwana, and the Atlantic Ocean formed. Eastern Laurasia was tectonically active as the Cimmerian plate continued to collide with Laurasia's southern coast, completely closing the Paleo-Tethys Ocean. A subd ...
