Eothyrididae
Eothyrididae is an extinct family of very primitive, insectivorous synapsids. Only three genera are known, ''Eothyris'', '' Vaughnictis'' and '' Oedaleops'', all from the early Permian of North America. Their main distinguishing feature is the large caniniform tooth in front of the maxilla. Eothyridids share with the Caseidae a number of specialised features associated with the morphology of the snout and external naris and it is likely that their common ancestor was close in build to ''Eothyris''. The two together form the clade Caseasauria. ''Eothyris'' is known from a single skull specimen; ''Oedaleops'' is known from three partial skulls and some parts of some limbs. ''Vaughnictis'' is known from a partial skull, six dorsal vertebrae and some hind-limb bones. The skulls are approximately six centimeters in length, suggesting that the total length of the animals was under one meter. The species were found in the lower Permian in what is today North America. In modern clad ...

Eothyris
''Eothyris'' is a genus of extinct synapsid in the family Eothyrididae from the early Permian. It was a carnivorous insectivorous animal, closely related to '' Oedaleops''. Only the skull of ''Eothyris'', first described in 1937, is known. It had a skull, and its total estimated length was . Eothyris is one of the most primitive synapsids known and is probably very similar to the common ancestor of all synapsids in many respects. The only known specimen of ''Eothyris'' was collected from the Artinskian-lower. Discovery and Historical Information ''Eothyris parkeyi'' was one of many new species of "pelycosaurs" discovered by Alfred Sherwood Romer as part of a series of paleontological expeditions for the Museum of Comparative Zoology (MCZ). The genoholotype (type specimen of a genus) and only known specimen of ''Eothyris'' is a complete skull and associated jaws, with the collection number MCZ 1161. This skull was collected about one mile west of the former Woodrum ranch-hou ...

Oedaleops
''Oedaleops'' is an extinct genus of caseasaur synapsids from the Early Permian of the southwestern United States. Fossils have been found in the Cutler Formation in New Mexico, which dates back to the Wolfcampian stage of the Early Permian. All remains belong to the single known species ''Oedaleops campi''. ''Oedaleops'' was closely related to ''Eothyris'', and both are part of the family Eothyrididae. Like ''Eothyris'', it was probably an insectivore. Discovery ''Oedaleops'' was first described by paleontologist Wann Langston Jr. in 1965 on the basis of a mostly complete skull (specimen UCMP 35758, the holotype of ''Oedaleops'') and a few isolated skull and postcranial fragments. The UCMP 35758 skull has been the sole specimen of ''Oedaleops'' used in most analyses of its evolutionary relationships. The more fragmentary specimens have been assigned to ''Oedaleops'' with caution because they are hard to distinguish from the bones of other Cutler Formation synapsids such as ''Ae ...

Caseasauria
Caseasauria is one of the two main clades of early synapsids, the other being the Eupelycosauria. Caseasaurs are currently known only from the Late Carboniferous and the Permian, and include two superficially different families, the small insectivorous or carnivorous Eothyrididae, and the large, herbivorous Caseidae. These two groups share a number of specialised features associated with the morphology of the snout and external naris. The ancestor of caseasaurs can be traced back to an insect eating or an omnivorous reptile-like synapsid from the Pennsylvanian time of the Carboniferous, possibly resembling ''Archaeothyris'', the earliest known synapsid. The caseasaurs were abundant during the later part of the Early Permian, but by the Middle Permian caseasaur diversity declined because the group was outcompeted by the more successful therapsids. The last caseasaurs became extinct at the end of the Guadelupian (Middle Permian). Description Among the most conspicuous charact ...

Caseidae
Caseidae are an extinct family of basal synapsids that lived from the Late Carboniferous to Middle Permian between about 300 and 265 million years ago. Fossils of these animals come from the south-central part of the United States (Texas, Oklahoma, and Kansas), from various parts of Europe (European Russia, France, Germany, Sardinia, and Poland), and possibly from South Africa if the genus ''Eunotosaurus'' is indeed a caseid as some authors proposed in 2021. Caseids show great taxonomic and morphological diversity. The most basal taxa were small insectivorous and omnivorous forms that lived mainly in the Upper Carboniferous and Lower Permian, such as ''Eocasea'', ''Callibrachion'', and '' Martensius''. This type of caseid persists until the middle Permian with ''Phreatophasma'' and may be ''Eunotosaurus''. During the early Permian, the clade is mainly represented by many species that adopted a herbivorous diet. Some have evolved into gigantic forms that can reach in length, such ...

Synapsid
Synapsids + (, 'arch') > () "having a fused arch"; synonymous with ''theropsids'' (Greek, "beast-face") are one of the two major groups of animals that evolved from basal amniotes, the other being the sauropsids, the group that includes reptiles and birds. The group includes mammals and every animal more closely related to mammals than to sauropsids. Unlike other amniotes, synapsids have a single temporal fenestra, an opening low in the skull roof behind each eye orbit, leaving a bony arch beneath each; this accounts for their name. The distinctive temporal fenestra developed about 318 million years ago during the Late Carboniferous period, when synapsids and sauropsids diverged, but was subsequently merged with the orbit in early mammals. Traditionally, non-mammalian synapsids were believed to have evolved from reptiles, and therefore described as mammal-like reptiles in classical systematics, and primitive synapsids were also referred to as pelycosaurs, or pelycosaur-gr ...

Asaphestera
''Asaphestera'' is an extinct genus of a tetrapod described on the basis of fossils from the Carboniferous of the Joggins locality in Nova Scotia, Canada. It was originally described as an undetermined lepospondyl and subsequently classified as a microsaur within the family Tuditanidae. A study published in May 2020 found that specimens referred to ''Asaphestera'' represented several unrelated species. Steen (1934)'s original species name ''Asaphestera platyris'' was retained for a skull which has been re-evaluated as the earliest known synapsid. The type species of ''Asaphestera'' is ''Asaphestera platyris'', named by Steen (1934) based on three skulls. Carroll & Gaskill (1978) noted that one of the skulls was briefly named as the species ''"Hylerpeton ''Hylerpeton'' is an extinct genus of leponspondyl amphibian belonging to the family Gymnarthridae from the late Carboniferous period. The nominal species ''"Hylerpeton" longidentatum'' Dawson, 1876 was considered possibly no ...

Robert L
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Prehistoric Synapsid Families
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 ...

Vincent Fernandez
Vincent Fernandez (born 31 January 1975) is a French former professional footballer who played as a goalkeeper. Born in Saint-Germain-en-Laye, Yvelines, Fernandez began his career with Paris Saint-Germain. He was loaned to LB Châteauroux to experience first-team football and when he returned to PSG, he became sub for Bernard Lama, and then Dominique Casagrande. The 1997–98 season was one of his best, because even though he did not play much in the championship, he still won two cups, playing in both the Coupe de la Ligue final and the Coupe de France final against Bordeaux and Lens respectively. In 1998 FC Sochaux, who had recently reached Ligue 1, offered him a place, which he took up and kept until Teddy Richert convinced him to play for RC Strasbourg. He played there for two years, but did not manage to shine, so he moved to the Ligue 2 Ligue 2 (, League 2), also known as Ligue 2 BKT due to sponsor (commercial), sponsorship by Balkrishna Industries, is a French profess ...
