Giant titanosaur (Dinosauria, Sauropoda) from the Late Cretaceous of Patagonia

Abstract

Nous rapportons la découverte d'un nouveau taxon titanosaurien, Puertasaurus reuili gen. et sp. nov., à partir de lits maastrichtiens de la Patagonie du Sud-Ouest. Quatre vertèbres ont été récupérées (c.-à-d., cervicale 9, dorsale 2 et deux médio-caudales). La nouvelle forme est diagnostiquée sur la base d'une colonne vertébrale neurale gonflée sur la vertèbre cervicale et d'une deuxième vertèbre dorsale extrêmement courte, entre autres caractéristiques. Puertasaurus est l'un des plus grands dino-saures sauropodes connus, avec une vertèbre dorsale 2 mesurant 168 cm de largeur transversale. C'est la première fois qu'une vertèbre cervicale est signalée pour un titanosaure géant, ce qui donne un nouvel aperçu de l'anatomie du cou des dinosaures néosauropodes.

Informamos del descubrimiento de un nuevo taxón de titanosaurio, Puertasaurus reuili gen. et sp. nov., de los lechos maastrichtianos de la Patagonia suroccidental. Se recuperaron cuatro vértebras (es decir, 9 cervicales, 2 dorsales y dos caudales medias). La nueva forma se diagnostica sobre la base de una columna neural inflada en la vértebra cervical y una segunda vértebra dorsal extremadamente corta, entre otras características. Puertasaurus es uno de los mayores dinosaurios saurópodos conocidos, con una vértebra dorsal 2 que mide 168 cm de ancho transversal. Esta es la primera vez que se reporta un vertebra cervical para un titanosaurio gigante, lo que brinda una nueva visión sobre la anatomía del cuello de los dinosaurios neosaurópodos.

We report the discovery of a new titanosaurian taxon, Puertasaurus reuili gen. et sp. nov., from Maastrichtian beds of SW Patagonia. Four vertebrae were recovered (i.e., cervical 9, dorsal 2, and two mid-caudals). The new form is diagnosed on the basis of an inflated neural spine on cervical vertebra, and extremely short second dorsal vertebra, among other features. Puertasaurus is one of the largest known sauropod dino-saurs, with dorsal vertebra 2 measuring 168 cm in transverse width. This is the first time that a cervical verte-bra is reported for a giant titanosaur, giving a new insight on neck anatomy of neosauropod dinosaurs.

نبلغ عن اكتشاف صنف تيتانوصوري جديد، Puertasaurus reuili gen. et sp. nov.، من أسرة ماستريختية في جنوب غرب باتاغونيا. تم استرداد أربع فقرات (أي عنق الرحم 9، الظهرية 2، واثنين من الذيلية الوسطى). يتم تشخيص الشكل الجديد على أساس العمود الفقري العصبي المنتفخ على فقرة عنق الرحم، والفقرات الظهرية الثانية القصيرة للغاية، من بين ميزات أخرى. Puertasaurus هي واحدة من أكبر ديناصورات الصوروبود المعروفة، مع فقرة ظهرية 2 بقياس 168 سم في العرض المستعرض. هذه هي المرة الأولى التي يتم فيها الإبلاغ عن عمود فقري عنقي لتيتانوصور عملاق، مما يعطي نظرة جديدة على تشريح الرقبة لديناصورات neosauropod.
