Pachypleurosaurs were primitive sauropterygian reptiles that vaguely resembled aquatic lizards, and were limited to the Triassic period. They were elongate animals, ranging in size from 20 cm to about a metre in length, with small heads, long necks, paddle-like limbs, and long deep tails. The are greatly reduced, so it is unlikely these animals could move about on land. The widely spaced peg-like teeth project at the front of the jaws, indicate that these animals fed on fish. In its subspecies Prosantosaurus, it could be observed that they fed on small fishes and crustaceans which they devoured entirely and that its teeth regrew after they broke off. This was the first observation of a teeth replacement on a European pachypleurosaurus, the only other discovery of such an event tooth was m

  • Die Pachypleurosauria sind eine ausgestorbene Gruppe mariner Reptilien. Gut erhaltene Fossilien wurden unter anderem im Tessin (CH) am Monte San Giorgio und in China entdeckt. (de)
  • I pachipleurosauri (Pachypleurosauria) sono un gruppo di rettili acquatici estinti appartenenti ai saurotterigi, vissuti nel Triassico medio (tra 242 e 235 milioni di anni fa). I loro resti fossili sono stati ritrovati in Europa e in Asia. (it)
  • Pachypleurosauria é um clado de répteis marinhos fósseis do clado do período Triássico. Eles foram animais alongados, medindo em torno de 20 centímetros a 1 metro de comprimento. Tradicionalmente é agrupado com o Nothosauria formando o clado Nothosauroidea. Rieppel (1999) demonstrou que o Pachypleurosauria formava um grupo-irmão com o Eusauropterygia que era formado pelo Nothosauroidea/Nothosauria e Pistosauroidea (incluindo Plesiosauria). Em 2013, uma análise cladística demonstrou que o grupo estava mais relacionado com o gênero e com o Nothosauroidea. (pt)
  • Пахиплеврозавр (Pachypleurosaurus) — род вымерших пресмыкающихся из группы завроптеригий (Sauropterygia) триасового периода. Пахиплеврозавры не относились непосредственно к группе , но состояли с ними в близком родстве. Они были довольно маленькими животными и, вероятно, обитали поблизости от берега или в лагунах, как современные морские игуаны. Возможно, они зародились в Китае, а затем мигрировали в Европу, передвигаясь по северному мелководью моря Тетис. Строение их черепа предполагает, что они охотились на мелкую рыбу и моллюсков. (ru)
  • 腫肋龍亞目（Pachypleurosauria）是種原始的鰭龍超目爬行動物，外表稍微地類似水生蜥蜴，只生存於三疊紀。牠們的體型修長，體型從20公分到1公尺長，並擁有小頭部、長頸部、鰭狀肢、長尾巴。牠們的肢帶（Limb Girdles）縮小許多，所以這群動物不太可能移動到陸地上。牠們的頜部前部佈滿釘狀牙齒，顯示這群動物以魚類為生。 腫肋龍亞目被歸類於幻龍目。在有些親緣分支分類法裡，腫肋龍類被認為是的姐妹分類單元，真鰭龍類演化支包括幻龍類與蛇頸龍類。 (zh)
  • Los paquipleurosaurios (Pachypleurosauria) son un grupo de reptiles sauropterigios primitivos que vagamente se parecían a lagartos acuáticos, y vivieron sólo durante el período Triásico. Eran animales alargados, con un rango de tamaños desde 20 centímetros hasta cerca de un metro de longitud, con pequeñas cabezas, cuellos largos, extremidades similares a aletas, y largas colas gruesas. La cintura escapular estaba muy reducida, por lo que es improbable que estos animales pudieran moverse en tierra. Los dientes como estacas ampliamente separados se proyectaban en el frente de las mandíbulas, lo que indica que estos reptiles se alimentaban de peces. (es)

  • Les Pachypleurosauridae ou pachypleurosauridés sont une famille de sauroptérygiens qui ressemblaient vaguement à des lézards aquatiques et qui ont vécu uniquement au Trias. C'étaient des animaux allongés, allant de 20 cm à un mètre environ de long, avec une petite tête, un cou long, des membres en forme de pagaie, et une très longue queue. Les ceintures des membres étaient fortement réduites, de sorte qu'il est peu probable que ces animaux puissent avoir pu se déplacer sur terre. Leurs dents très espacées et projetées vers l'avant, indiquent qu'ils se nourrissaient de poissons. (fr)
