Anoualerpeton Priscus Holotype Premaxilla
''Anoualerpeton'' is an extinct genus of lissamphibian in the family Albanerpetontidae. It is the oldest and most primitive albanerpetontid known. Fossils have been found of two different species, ''Anoualerpeton priscus'' from the Middle Jurassic (Bathonian) aged Forest Marble and Kilmaluag formations of England and Scotland, and ''Anoualerpeton unicus'' from Late Jurassic-Early Cretaceous (Tithonian-Berriasian) Ksar Metlili Formation of Morocco. ''A. unicus'' is the only named albanerpetontid from Gondwana. Etymology The name "''Anoualerpeton''" is composed of Anoual, the name of a city in the eastern High Atlas (Morocco), in whose relative proximity the type material of the type species ''Anoualerpeton unicus'' was found, and the ancient Greek word ἑρπετόν herpeton, which means 'creeping animal" and is often used in the generic names of fossil amphibians. The epithets "priscus" and "unicus" mean 'old' and 'unique', which refers to the fact that ''Anoualerpeton'' ...

Bathonian
In the geologic timescale the Bathonian is an age and stage of the Middle Jurassic. It lasted from approximately 168.3 Ma to around 166.1 Ma (million years ago). The Bathonian Age succeeds the Bajocian Age and precedes the Callovian Age. Stratigraphic definitions The Bathonian Stage takes its name from Bath, a spa town in England built on Jurassic limestone (the Latinized form of the town name is ''Bathonium''). The name was introduced in scientific literature by Belgian geologist d'Omalius d'Halloy in 1843. The original type locality was located near Bath. The French palaeontologist Alcide d'Orbigny was in 1852 the first to define the exact length of the stage. The base of the Bathonian is at the first appearance of ammonite species '' Parkinsonia (Gonolkites) convergens'' in the stratigraphic column. The global reference profile for the base of the Bathonian (a GSSP) was ratified as Ravin du Bès, Bas-Auran area, Alpes de Haute Provence, France in 2009. The top of the Bat ...

Wesserpeton
''Wesserpeton'' is an extinct genus of albanerpetontid amphibian known from the Isle of Wight, southern England. Description ''Wesserpeton'' is known from the holotype NHMUK PV R36521, nearly complete fused frontals and from the referred materials NHMUK PV R36522–36568 and R36595–36611. All specimens were collected from seven localities of the Wessex Formation on the southeastern coast of the Isle of Wight of southern England. The type locality (Bed 38) is exposed at Yaverland while the rest (Bed L2) are exposed high in the cliff at Sudmoor Point but have yielded only NHMUK PV R36539, R36522 and R36553–36558. All specimens are dating to the Barremian stage of the Early Cretaceous. Etymology ''Wesserpeton'' was first named by Steven C. Sweetman and James D. Gardner in 2013 and the type species is ''Wesserpeton evansae''. The generic name is derived from ''Wess'', from Wessex, an ancient British kingdom which included the Isle of Wight, an ...

La Huérguina Formation
The La Huérguina Formation (also known as the Calizas de La Huérguina Formation, La Huérguina Limestone Formation or as the Una Formation) is a geological formation in Spain whose strata date back to the Barremian stage of the Early Cretaceous.Martínez et al., 2017 Las Hoyas is a Konservat-Lagerstätte within the formation, located near the city of Cuenca, Spain. The site is mostly known for its exquisitely preserved dinosaurs, especially enantiornithines.Weishampel et al., 2004, pp.556-563 The lithology of the formation mostly consists of lacustarine limestone deposited in a freshwater wetland environment. Las Hoyas Taphonomy As a Konservat-Lagerstätten, the preservation is exceptional. This may be a result of three factors: Microbial mats, Obruption and Stagnation. Microbial mats may be responsible for the preservation of soft tissue in many fossils from Las Hoyas, like ''Pelecanimimus''' crest. The iron carbonate depositions, a result from bacterial metabolism whic ...

Isle Of Skye
The Isle of Skye, or simply Skye (; gd, An t-Eilean Sgitheanach or ; sco, Isle o Skye), is the largest and northernmost of the major islands in the Inner Hebrides of Scotland. The island's peninsulas radiate from a mountainous hub dominated by the Cuillin, the rocky slopes of which provide some of the most dramatic mountain scenery in the country. Slesser (1981) p. 19. Although has been suggested to describe a winged shape, no definitive agreement exists as to the name's origins. The island has been occupied since the Mesolithic period, and over its history has been occupied at various times by Celtic tribes including the Picts and the Gaels, Scandinavian Vikings, and most notably the powerful integrated Norse-Gaels clans of MacLeod and MacDonald. The island was considered to be under Norwegian suzerainty until the 1266 Treaty of Perth, which transferred control over to Scotland. The 18th-century Jacobite risings led to the breaking-up of the clan system and later cleara ...

Mammaliaformes
Mammaliaformes ("mammalian forms") is a clade that contains the crown group mammals and their closest Extinction, extinct relatives; the group adaptive radiation, radiated from earlier probainognathian cynodonts. It is defined as the clade originating from the most recent common ancestor of Morganucodonta and the crown group mammals; the latter is the clade originating with the most recent common ancestor of extant Monotremata, Marsupialia, and Placentalia. Besides Morganucodonta and the crown group mammals, Mammaliaformes includes Docodonta and ''Hadrocodium'' as well as the Triassic ''Tikitherium'', the earliest known member of the group. Mammaliaformes is a term of phylogenetic nomenclature. In contrast, the assignment of organisms to Mammalia has traditionally been founded on traits and, on this basis, Mammalia is slightly more inclusive than Mammaliaformes. In particular, trait-based taxonomy generally includes ''Adelobasileus'' and ''Sinoconodon'' in Mammalia, though they fa ...

Tongue And Groove
Tongue and groove is a method of fitting similar objects together, edge to edge, used mainly with wood, in flooring, parquetry, panelling, and similar constructions. Tongue and groove joints allow two flat pieces to be joined strongly together to make a single flat surface. Before plywood became common, tongue and groove boards were also used for sheathing buildings and to construct concrete formwork. A strong joint, the tongue and groove joint is widely used for re-entrant angles. The effect of wood shrinkage is concealed when the joint is beaded or otherwise moulded.Tongue and GrooveWoodworkDetails.com/ref> In expensive cabinet work, glued dovetail and multiple tongue and groove are used. Each piece has a slot (the ''groove'' or '' dado'') cut all along one edge, and a thin, deep ridge (the ''tongue'') on the opposite edge. The tongue projects a little less than the depth of the groove. Two or more pieces thus fit together closely. The joint is not normally glued, as shrink ...

Albanerpeton Nexuosus
''Albanerpeton'' is an extinct genus of salamander-like lissamphibian found in North America and Europe, first appearing in Cretaceous-aged strata. There are eight described members of the genus, and one undiagnosed species from the Paskapoo Formation, with the most recent, ''A. ektopistikon'' being described by Carrano ''et al.''in 2022. Members of the genus had a robust head and neck which likely allowed them to actively burrow, characteristic of fossorial species, and they lived in a wide range of environments. This genus of amphibian was the last of its order, surviving until the late Pliocene in southern Europe, and into the Early Pleistocene ( Gelasian) of northern Italy. It likely became extinct when the region developed its present Mediterranean-type climate, having preferred one that was cold and humid. The monophyly of ''Albanerpeton'' has recently been questioned History and Discovery Albanerpeton was first described by Estes and Hoffstetter in 1976. However, the genu ...
