Cheliderpeton Vrayni
''Cheliderpeton'' (often misspelled ''Chelyderpeton'') is an extinct genus of temnospondyl amphibian. It lived during the Early Permian in what is now Europe. Fossils have been found from the Ruprechtice horizon of the Intrasudetic Basin of Bohemia in the Czech Republic, as well as the Saar-Nahe Basin of southwestern Germany. ''Cheliderpeton'' had a 16 cm skull, and reached about 65 cm in length.http://www.angellis.net/Web/PDfiles/amphs.pdf The type species of ''Cheliderpeton'' is ''Chelidosaurus vranyi'', named in 1877 by the Czech paleontologist Antonin Fritsch and found from the Czech Republic. The preoccupied generic name, referring to the trunk armour of turtles, was first changed into ''Chelydosaurus'' in 1885 and finally into ''Cheliderpeton'' in 1887. A second species named ''C. latirostre'' was described in 1993 by J. A. Boy from Germany, after having been assigned to ''Archegosaurus''. It differs from the type in having a less extensive preorbital region ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Archegosaurus
''Archegosaurus'' is a genus of temnospondyl amphibian which lived during the Asselian to Wuchiapingian stages of the Permian, around 299-253 million years ago. The remains of this animal, consisting of at least 90 partial skeletons (mostly skulls), have been found in Germany. The name ''Archegosaurus'' was coined by Goldfuss in 1847. ''Archegosaurus'' is a member of Archegosauridae and is that family's type genus. Classification In 1938, paleontologist Margaret C. Steen described a temnospondyl from the Permian-age Ruprechtice assemblage in northeast Bohemia. Steen named it ''Memonomenos dyscriton'' on the basis of a skull that was narrower than others in the Ruprechtice. It was classified as an anthracosaur, a group closely related to reptiles. Both ''Memonomenos'' and embolomere anthracosaurs had vertebrae that were divided into several parts, including a pleurocentrum and intercentrum. Animals with this type of divided vertebrae were said to be rachitomi. During the early t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autun
Autun () is a subprefecture of the Saône-et-Loire department in the Bourgogne-Franche-Comté region of central-eastern France. It was founded during the Principate era of the early Roman Empire by Emperor Augustus as Augustodunum to give a Roman capital to the Gallic people Aedui, who had Bibracte as their political centre. In Roman times the city may have been home to 30,000 to 100,000 people, according to different estimates. Nowadays, the commune has a population of about 15,000. Geography The commune lies in the northwest of the department. History Early history Augustodunum was founded during the reign of the first Roman emperor, Augustus, after whom it was named. It was the civitas "tribal capital" of the Aedui, Continental Celts who had been allies and "brothers" (') of Rome since before Julius Caesar's Gallic Wars. Augustodunum was a planned foundation replacing the original oppidum Bibracte, located some away. Several elements of Roman architecture such as wall ...

Choana
The choanae (singular choana), posterior nasal apertures or internal nostrils are two openings found at the back of the nasal passage between the nasal cavity and the throat in tetrapods, including humans and other mammals (as well as crocodilians and most skinks). They are considered one of the most important synapomorphies of tetrapodomorphs, that allowed the passage from water to land. In animals with secondary palates, they allow breathing when the mouth is closed. Janvier, Philippe (2004) "Wandering nostrils". ''Nature'', 432 (7013): 23–24. In tetrapods without secondary palates their function relates primarily to olfaction (sense of smell). The choanae are separated in two by the vomer. Boundaries A choana is the opening between the nasal cavity and the nasopharynx. It is therefore not a structure but a space bounded as follows: * anteriorly and inferiorly by the horizontal plate of palatine bone, * superiorly and posteriorly by the sphenoid bone * laterally by t ...

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 the ...

Ural (region)
Ural (russian: Урал) is a geographical region located around the Ural Mountains, between the East European and West Siberian plains. It is considered a part of Eurasian Steppe, extending approximately from the North to the South; from the Arctic Ocean to the end of the Ural River near Orsk city. The border between Europe and Asia runs along the Eastern side of the Ural Mountains. Ural mostly lies within Russia but also includes a small part of Northwestern Kazakhstan. This is a historical, not an official entity, with borders overlapping its Western Volga and Eastern Siberia neighboring regions. At some point in the past, parts of the currently existing Ural region were considered a gateway to Siberia, or even Siberia itself, and were combined with the Volga administrative the divisions. Today, there are two official namesake entities: the Ural Federal District and the Ural economic region. While the latter follows the historical borders, the former is a political product; t ...

Intasuchus
''Intasuchus'' is an extinct genus of temnospondyl amphibian from the Middle Permian of Russia. It is known from a single species, ''Intasuchus silvicola'', which was named in 1956. ''Intasuchus'' belongs to the family Intasuchidae and is probably its sole member, although other taxa such as ''Syndyodosuchus'' and ''Cheliderpeton'' have been assigned to the family in the past. ''Intasuchus'' most likely belongs to the group Archegosauroidea, Permian relatives of the large, mostly Mesozoic temnospondyl clade Stereospondyli. Description ''Intasuchus'' has a long, flattened skull that narrows slightly toward the front. Prominent ridges run along the skull surface from the eye sockets to the nostril openings. The otic notch at the back of the skull is relatively narrow in comparison to other temnospondyls, although it extends as a groove along the sides of the skull table. ''Intasuchus'' has large teeth on the roof of its mouth, with a large row between two openings of the palate call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal, inferior n ...

Nasal Bone
The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose. Each has two surfaces and four borders. Structure The two nasal bones are joined at the midline internasal suture and make up the bridge of the nose. Surfaces The ''outer surface'' is concavo-convex from above downward, convex from side to side; it is covered by the procerus and nasalis muscles, and perforated about its center by a foramen, for the transmission of a small vein. The ''inner surface'' is concave from side to side, and is traversed from above downward, by a groove for the passage of a branch of the nasociliary nerve. Articulations The nasal articulates with four bones: two of the cranium, the frontal and ethmoid, and two of the face, the opposite nasal and the maxilla.
