“…In this regard BIBE 45854 again stands in marked contrast to the saltasaurines Saltasaurus and Neuquensaurus, taxa in which the cervical postzygapophyses project far posterior beyond their respective centra. The cervical postzygapophyses also reach to or beyond the posterior rim of the centra in other titanosaurs, such as Isisaurus colberti, Rapetosaurus krausei and Overosaurus paradasorum (Jain & Bandyopadhyay 1997;Curry Rogers 2009;Coria et al 2013). The presence of short postzygapophyses in BIBE 45854 more closely resembles the condition in Dreadnoughtus schrani, some posterior cervical vertebrae of Malawisaurus dixeyi, Trigonosaurus pricei, brachiosaurids, Sauroposeidon proteles and TMM 43621-1 (Wedel et al 2000a, b;Lehman & Coulson 2002;Campos et al 2005;Gomani 2005;Lacovara et al 2014).…”

The sauropod dinosaur Alamosaurus sanjuanensis Gilmore, 1922 has been known from Maastrichtian deposits of southwestern North America for nearly a century. Alamosaurus is the youngest sauropod taxon known in North America. Originally described from an isolated scapula and ischium from New Mexico, more of Alamosaurus was revealed by an incomplete skeleton from southern Utah. Additional referred specimens from western Texas provided the first few examples of cervical, dorsal and sacral vertebrae known for the taxon, but these came from relatively small and immature individuals. Here we describe an articulated series of cervical vertebrae of a large, mature titanosaur from Big Bend National Park, Texas, and provide evidence that the specimen can be referred to A. sanjuanensis. The specimen represents the first articulated cervical vertebral series described for the taxon, which clarifies aspects of cervical vertebral anatomy and provides at least one new diagnostic character for Alamosaurus. Many previous cladistic analyses found Alamosaurus to be a saltasaurid titanosaur, sometimes closely related to the Asian taxon Opisthocoelicaudia skarzynskii. We present cladistic analyses incorporating new data from this and other specimens from Big Bend National Park. The first places Alamosaurus as a lithostrotian titanosaur outside Saltasauridae. The second analysis, with greater focus on South American titanosaurs, finds Alamosaurus allied to Lognkosauria, a clade of South American titanosaurs notable for giant size and exceptionally robust necks. This relationship may be more congruent with the fossil record than hypotheses of phylogeny that would require saltasaurid titanosaurs to inhabit northern Laramidia, Beringia and Central Asia through the late Campanian and Maastrichtian while leaving no record of their presence.

,4bstraet: A large and diverse collection of vertebrate remains from the Campanian-Maastrichtian Allen Formation (Malargiie Group) a t the Bajo de Santa Rosa locality (Rio Negro Province, Argentina) is described hore. The vertebrates arc represented hv: chondrichthvans: di~iomvstid siluriform. le~isosteid, cf oercichthvid and titanosaurid dinosaurs. A now small salt,asaurine tit&saurid, I3onatitan reigigen. el sp. no"., is described. It is diagnosed by the following association of characters: 1) longitudinal groovo located an the suture between pariotals that continues posteriorly over the supraoccipital to the foramen magnum; 2) basisphcnoid tubera long and narrow; 3) dorsalto middle caudal vertebrae with deep oval to circular pits present on both sides of the prespinal lamina; 4) anterior caudal vertebra with spino-postzygapophysiat and spino-prezygapophysiai laminae; 5) neural arch of anterior caudals with deep interzygapophysial fossae with numerous pits; 6 ) anterior caudal vertebra with an accessom sub-horizontal lamina extendine from the antero-ventral oortion of the " postzygapophysis to the mid-portion of tho spino-prezygapophysial lamina; and finally, 7) anterior caudal vertobra with a prominent axial crest on the ventral surftaee of tho cerntrum. The first rocord of sphenodonts and cf carcharodontosaurid theropods is recognized for the upper Late Cretaceous ofpatagonia, as well as the earliest record of perichthylds (Pereiformes). The vertebrate record is mainly composed of terrestrial and freshwater tawa, but a few marine elements are found (olasmosaurids) indicating a marine influence during the deposition of the Allen hrmation in the arca of Baio de Santa Rosa.

-ASSIGNABLE MATERIAL TO EPACHTHOSAURUS POWELL, 1990 (SAUROPODA: TITANOSAURIA), FROM THE BAJO BARREAL FORMATION, UPPER CRETACEOUS, CHUBUT, ARGENTI-NA. This paper describes materials recovered from levels of the Bajo Barreal Formation (Upper Cretaceous) of Ranch Ocho Hermanos outcrops, Patagonia, Argentina. The materials include an anterior dorsal vertebra and pelvic elements. The large sized dorsal vertebra is assigned to the taxon Epachthosaurus based on the following diagnostic characters which are autapomorphic for the above mentioned taxon: strongly developed intraprezygapophyseal lamina, accessory articular processes extending ventrolaterally from the hyposphene, and aliform processes which project laterally from the dorsal margin of the spinodiapophyseal lamina. The incomplete sacrum has five sacral vertebrae and a portion of the right ilium and pubis. These materials are included within Titanosauria and tentatively pertain to Epachthosaurus. The study of the above mentioned materials is important because it increases our knowledge of the relative abundance of the taxon Epachthosaurus in Ocho Hermanos ranch outcrops. Furthermore, we propose a set of characters which allow the expansion of the generic diagnosis of Epachthosaurus.Key words: Epachthosaurus, Titanosauria, Late Cretaceous, Patagonia, Argentina.RESUMO -Descrevem-se aqui materiais fósseis de dinossauros coletados em níveis da Formação Bajo Barreal (Cretáceo Superior) do afloramento Estância Ocho Hermanos, Patagônia Argentina, consistindo de uma vértebra dorsal anterior e de elementos pélvicos. A vértebra dorsal, de grande tamanho, apresenta os seguintes caracteres diagnósticos: (i) lâmina intraprezigapofiseal bem desenvolvida; (ii) processos articulares acessórios estendendo-se ventrolateralmente do hiposfeno; e (iii) processos aliformes que se projetam lateralmente da margem dorsal da lâmina espinodiapofiseal. A pélvis está incompleta, apresentando cinco vértebras sacrais, uma porção do ílio direito e um fragmento de púbis. Atribui-se estes materiais a Titanosauria e, tentativamente, como pertencentes a Epachthosaurus, a partir dos caracteres diagnósticos, que são considerados autapomórficos para este táxon. O estudo destes materiais aumenta o conhecimento sobre a relativa abundância desse gênero para a área de ocorrência dos fósseis, em particular, e permite sugerir um conjunto de caracteres que possibilita expandir a diagnose genérica de Epachthosaurus.
