Baryonychinae (original) (raw)
Baryonychinae (il cui nome significa "artigli pesanti") è una sottofamiglia estinta di dinosauri teropodi spinosauridi vissuti nel Cretaceo inferiore-superiore, circa 139-112 milioni di anni fa (Barremiano-Aptiano), i cui resti sono stati ritrovati principalmente in Europa, Africa e, forse, in Australia. Questa sottofamiglia comprende i generi Baryonyx, Cristatusaurus, Suchosaurus, e la tribù Ceratosuchopsini che comprende Ceratosuchops, Riparovenator e Suchomimus. La differenza principale tra gli Spinosaurinae e i Baryonychinae è l'assenza di processi spinali allungati comuni negli Spinosaurinae e un cranio più compatto dalla differente forma della premascella con una piccola cresta ossea dinanzi agli occhi, presente in entrambe le sottofamiglie.

| dbo:abstract | Baryonychinae is an extinct clade or subfamily of spinosaurids from the Early Cretaceous (Valanginian-Albian) of Britain, Portugal, and Niger. In 2021, it consisted of six genera: Ceratosuchops, Cristatusaurus, Riparovenator, Suchomimus, Suchosaurus, and Baryonyx, the nominal genus. The clade was named by Charig & Milner in 1986 and defined by Sereno et al. in 1998 and Holtz et al. in 2004 as all taxa more closely related to Baryonyx walkeri than to Spinosaurus aegyptiacus. Baryonychines were large, bipedal predators with elongated, crocodile-like skulls and lower jaw tips fanning out into rosettes bearing conical, often unserrated, teeth, and a distinct premaxillary notch. They possessed robust forelimbs supporting three-fingered hands with an enlarged first digit claw, to which the subfamily name indirectly refers. Members of this group, unlike the more derived Spinosaurinae, sported only low sails or none at all.

(pl) De Baryonychinae vormen een onderverdeling van de Spinosauridae, een groep uit de Theropoda, vleesetende dinosauriërs. Een onderfamilie Baryonychinae werd impliciet benoemd door Alan Jack Charig in 1986, toen hij bij zijn beschrijving van Baryonyx een familie Baryonychidae benoemde. De eerste die de naam echt gebruikte was Paul Sereno in 1998, toen hij een klade Baryonychinae definieerde : de groep bestaande uit Baryonyx en alle soorten die nauwer verwant zijn aan Baryonyx dan aan Spinosaurus. In 2004 gaf een inhoudelijk identieke definitie waarin hij de soortnamen toevoegde: Baryonyx walkeri en Spinosaurus aegyptiacus. Uit welke soorten de klade in feite bestaat, is zeer omstreden; behalve Baryonyx zelf uit het Barremien van Engeland, vermoedelijk Suchomimus tenerensis uit het Albien van Afrika. De groep bestaat uit grote tweevoetige roofdieren met een lage langgerekte kop, wellicht viseters. De bekende vormen hebben geen hoge rugkam. Mogelijke soorten zijn: * Baryonyx * Ceratosuchops * Cristatusaurus (= Baryonyx?) * Iberospinus? * Riparovenator * Suchomimus (= Cristatusaurus/Baryonyx?) * Suchosaurus (= Baryonyx?) * Vallibonavenatrix? * ? (nl) Baryonychinae é um clado extinto ou subfamília de espinossaurídeos do Cretáceo Inferior (Valanginiano-Albiano) da Grã-Bretanha, Portugal e Níger. Em 2021, consistia em seis gêneros: Ceratosuchops, Cristatusaurus, Riparovenator, Suchomimus, e Baryonyx, o gênero nominal. O clado foi nomeado por Charig & Milner em 1998 e definido por Holtz et al. em 2004 como todos os taxa mais intimamente relacionados com Baryonyx walkeri do que com Spinosaurus aegyptiacus. Os membros deste clado eram grandes predadores bípedes com crânios alongados semelhantes a crocodilos e pontas da mandíbula inferior que se espalhavam em rosetas com dentes cônicos, muitas vezes não serrilhados, e um entalhe pré-maxilar distinto. Eles possuíam membros anteriores robustos que suportavam mãos de três dedos com uma garra alargada do primeiro dedo, à qual o nome da subfamília se refere indiretamente. Os membros deste grupo, ao contrário dos Spinosaurinae mais derivados, ostentavam apenas velas baixas ou nenhuma. (pt) |
