Lepidosauromorpha ( German )

provided by wikipedia DE

Die Lepidosauromorpha sind ein Taxon der Reptilien bzw. Sauropsiden, das die Lepidosauria (Brückenechsen und Schuppenkriechtiere) einschließt sowie alle diapsiden Reptilien, die näher mit den Lepidosauria als mit den Archosauria (Krokodilen und Vögeln) verwandt sind. Dieses Taxon wird in erster Linie in der Paläontologie verwendet, da alle Subtaxa außerhalb der Lepidosauria ausgestorben sind.

Merkmale

Im Gegensatz zu den Archosauriern behalten die Lepidosauromorphen die primitive Fortbewegung der frühen Tetrapoda durch die seitliche, schlängelnde Bewegung der Wirbelsäule bei. Sie entwickeln bereits im Oberen Perm ein Sternum, das aber eine andere Struktur und Funktion als das der Archosaurier hat und nicht homolog mit diesem ist. Das Sternum erweitert den Bewegungsspielraum der Vorderbeine. Außerdem behalten sie die spreizbeinige Stellung der Extremitäten und zeigen keine Tendenz sie unter den Körper zu stellen, wie es beispielsweise die Dinosaurier taten.

Systematik

Zu den Lepidosauromorpha gehören neben den Schuppenechsen (Lepidosauria) die Vertreter aus der vollständig ausgestorbenen Gruppe Sauropterygia, die den Großteil der mesozoischen Meeresreptilien stellen, sowie einige weitere Vertreter aus dem Mesozoikum. Schwestergruppe der Lepidosauromorpha sind die Archosauromorpha. Unter der Annahme, dass die Schildkröten (Testudines) keine unabhängige Linie der Reptilienevolution darstellen und entweder den Lepidosauromorpha oder den Archosauromorpha zuzurechnen sind, bilden diese beiden Großgruppen die Reptilien-Kronengruppe.

Lepidosauromorpha

provided by wikipedia EN

Lepidosauromorpha (in PhyloCode known as Pan-Lepidosauria[2][3]) is a group of reptiles comprising all diapsids closer to lizards than to archosaurs (which include crocodiles and birds). The only living sub-group is the Lepidosauria, which contains two subdivisions, Squamata, which contains lizards and snakes, and Rhynchocephalia, the only extant species of which is the tuatara.

Lepidosauromorphs are distinguishable from archosauromorphs (reptiles closer to archosaurs) by their primitive sprawling gait (allowing for the same sinusoidal trunk and tail movement seen in fish), the sliding "joint" between the coracoids and the sternum (for a longer stride), and their pleurodont dentition. In contrast, Archosauromorphs possess a parasagittal gait, a reduction in their dermal girdle, a reduction and/or loss of the sternum, and a more thecodont dentition. Living lepidosauromorphs have retained an ectothermic ("cold blooded") metabolism, unlike the ancestral condition in archosauromorphs.

While some putative stem-lepidosauromorphs like Palaeagama are known from the Late Permian, the oldest definitive lepidosauromorphs, Sophineta and Paliguana, are known from the Early Triassic.[4][5] Taytalura from the early Late Triassic of Argentina is the most complete fossil of an early lepidosauromorph and is one of the few fossils robustly inferred as an early evolving lepidosauromorph.[6] The Kuehneosauridae, a family of reptiles with elongated ribs which allowed them to glide akin to living gliding lizards have been historically typically considered early lepidosauromorphs. However, several recent studies have been found them in other positions within Sauria, including Archosauromorpha.[7] Almost all non-lepidosaurian lepidosauromorphs became extinct by the end of the Triassic, the with the latest non lepidosaur-lepidosauromorphs being Marmoretta from the Middle Jurassic of Britain and an indeterminate form from the Middle Jurassic Moskvoretskaya Formation of Russia, which appear to be closely related to Fraxinisaura from the Middle Triassic of Germany.[5][8][9] Other studies have recovered Marmoretta as a stem-squamate.[10]

Lepidosauromorpha on diapsidien kladi, joka käsittää kaikki diapsidit, jotka ovat läheisempää sukua suomumatelijoille kuin arkosaureille (joka käsittää nykyiset krokotiilieläimet ja linnut). Sen ainoa elossa oleva alaryhmä on Lepidosauria, johon luetaan nykyiset liskot, käärmeet, matoliskot ja tuatara.

Lepidosauromorpha ( French )

provided by wikipedia FR

Les Lépidosauromorphes (Lepidosauromorpha) sont une infra-classe de vertébrés tétrapodes de la sous-classe des diapsides[1]. Ils constitue la branche des espèces plus proches des lépidosaures que des archosaures au sein du groupe-couronne Sauria. Leur groupe frère est celui des Archosauromorphes aujourd'hui représenté par les crocodiles et les oiseaux.

Contenu

Les lépidosauromorphes comprennent d'une part les Lépidosaures (sphénodontes, lézards, serpents et iguanes) et quelques groupes éteints, et d'autre part les Sauroptérygiens (reptiles marins) tous éteints (plésiosaures, etc.). Les tortues (Testudines) pourraient aussi faire partie de ce groupe.

Lepidosauromorpha ( Italian )

provided by wikipedia IT

Lepidosauromorpha è un gruppo di rettili comprendente tutti i diapsidi correlati più alle lucertole che agli arcosauri (inclusi i coccodrilli e gli uccelli). L'unico sottogruppo vivente è quello dei lepidosauri, che comprendono lucertole, serpenti, e tuatara.

I Lepidosauromorpha sono distinguibili dagli Archosauromorpha grazie alla loro primitiva andatura tentacolare, che si traduce in un movimento sinusoidale di tronco e coda simile a quello osservabile nei pesci, e alla loro dentatura pleurodonte. In contrasto, gli arcosauromorfi possiedono un'andatura parasagittale, una riduzione della loro guaina dermale, una riduzione o perdita dello sterno e una dentizione più tecodonte.

I lepidosauromorfi hanno mantenuto il sangue freddo principalmente a causa del loro andamento tentacolare a basso consumo energetico.

Lepidozauromorfy ( Polish )

provided by wikipedia POL

Lepidozauromorfy (Lepidosauromorpha) – infragromada gadów z podgromady Diapsida. Według definicji przedstawionej przez Jacques'a Gauthiera i współpracowników (1988) obejmuje wszystkich przedstawicieli kladu Sauria bliżej spokrewnionych z hatterią i łuskonośnymi niż z archozaurami. Według autorów tak definiowane lepidozauromorfy obejmowałyby Younginiformes, Paliguana whitei, Palaeagama vielhaueri, Saurosternon bainii, Kuehneosauridae, sfenodonty oraz łuskonośne[1]. Późniejsze analizy kladystyczne sugerują jednak, że Younginiformes były diapsydami nie należącymi do Sauria, a tym samym nie mogły być lepidozauromorfami[2][3][4][5][6]. Kwestionowana bywa też przynależność rodzajów Palaeagama, Paliguana i Saurosternon oraz rodziny Kuehneosauridae do lepidozauromorfów – niektóre analizy kladystyczne sugerują, że i one mogły być diapsydami nienależącymi do Sauria[5][6]. Część naukowców zalicza do lepidozauromorfów także zauropterygi[3][4][6], grupy Thalattosauria[7] i Choristodera[6], rodzinę Drepanosauridae[8] oraz żółwie[3][4][6]. Lepidozauromorfy są znane w zapisie kopalnym od permu[9].

鱗竜形類
Lepidosauromorphs
生息年代:
三畳紀前期 - 完新世
Tuatara.jpg 地質時代 三畳紀前期 - 完新世現代分類 : 動物界 Animalia : 脊索動物門 Chordata 亜門 : 脊椎動物亜門 Vertebrata : 爬虫綱 Reptilia 亜綱 : 双弓亜綱 Diapsida 下綱 : 鱗竜形類 Lepidosauromorpha シノニム

Ankylopoda (Obsolete Clade)

下位分類

鱗竜形類(りんりゅうけいるい、英語: Lepidosauromorpha)は双弓類の下位グループである爬虫類のグループで、現存する唯一の下位グループは鱗竜類(Lepidosauria)(トカゲヘビミミズトカゲムカシトカゲなど)。ワニ鳥類を含む主竜類(Archosauromorpha)とは比較的近類(最近ではカメは主竜類に近いことがわかってきている)。鱗竜形類はペルム紀にはカメ及び主竜類の祖先(主竜形類)と分岐し、続く三畳紀には適応放散を果たし、鰭竜類(首長竜などを含むグループ)などを生み出した。[1]

鱗竜形類は主竜形類(主竜類)と異なり、より原始的な這う姿勢をとり、魚のような正弦波を描く動作で移動し、烏口骨胸骨をつなぐ関節を持ち、面生歯を持つ。比較して主竜形類は、矢状面歩行で移動し、より小さな皮骨を持ち、胸骨がより小さいか失われており、槽歯類歯列(ソケットに収まった歯)を持つ。

鱗竜形類は這う姿勢をとるため大量のエネルギーを浪費する必要はなく、現生のものは全て変温動物である。
