Filippini, F.S., Otero, A. & Gasparini, Z., June 2016. The phylogenetic relevance of the sacrum among macronarian sauropods: insights from a pelvis from the Upper Cretaceous of Patagonia, Argentina. Alcheringa 41, xxx–xxx. ISSN 0311-5518. Anatomical variation in the sacrum is useful for differentiating sauropod lineages. Morphological variation in the sacrum has been underestimated mainly because of its anatomical complexity and uncertain homologies with presacral and postsacral elements. We… 

The Axial Skeleton of Rinconsaurus caudamirus (Sauropoda: Titanosauria) from the Late Cretaceous of Patagonia, Argentina

Abstract. Titanosaurs were the predominant herbivores during the Late Cretaceous, inhabiting all continents. This clade was especially diverse in South America with some of the largest and smallest

Investigating the enigmatic Aeolosaurini clade: the caudal biomechanics of Aeolosaurus maximus (Aeolosaurini/Sauropoda) using the neutral pose method and the first case of protonic tail condition in Sauropoda

ABSTRACT The neck posture and function in sauropods have been widely studied during the last decades. The cartilaginous neutral pose (CNP) method is commonly used in biomechanical reconstructions by

Reappraisal of Austrosaurus mckillopi Longman, 1933 from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur

Poropat, S.F., Nair, J.P., Syme, C.E., Mannion, P.D., Upchurch, P., Hocknull, S.A., Cook, A.G., Tischler, T.R. & Holland, T. XX.XXXX. 2017. Reappraisal of Austrosaurus mckillopi Longman, 1933 from

The first dinosaurs from the Early Cretaceous Hami Pterosaur Fauna, China

Besides the pterosaur Hamipterus and one theropod tooth, these dinosaurs are the first vertebrates reported in this region, increasing the diversity of the fauna as well as the information on Chinese sauropods, further supporting a widespread diversification of somphospondylans during the Early Cretaceous of Asia.

Sacral co‐ossification in dinosaurs: The oldest record of fused sacral vertebrae in Dinosauria and the diversity of sacral co‐ossification patterns in the group

The new specimen described here indicates that the fusion of sacral elements occurred early in the evolution of dinosaurs, and suggests that primordial sacral vertebrae fuse earlier in the lineage (as seen in Norian sauropodomorphs).



Osteology and phylogenetic relationships of Tehuelchesaurus benitezii (Dinosauria, Sauropoda) from the Upper Jurassic of Patagonia

The phylogenetic relationships of this taxon are tested through an extensive cladistic analysis that recovers Tehuelchesaurus as a non-titanosauriform camarasauromorph, deeply nested within Neosauropoda.


A new titanosaurid dinosaur from the Late Cretaceous continental deposits of the Bauru Group is described, diagnosed by a combination of characters such as elongated cervicals and middorsals, dorsal vertebrae 9 and 10 with incipient postzygodiapophyseal lamina and transverse processes well developed throughout the sequence formed by anterior and medial caudals.

The postcranial osteology of Rapetosaurus krausei (Sauropoda: Titanosauria) from the Late Cretaceous of Madagascar

ABSTRACT Rapetosaurus krausei is a titanosaur sauropod from the Upper Cretaceous Maevarano Formation of northwestern Madagascar and is among the most complete titanosaurs ever discovered. To date,

A New Sauropodomorph Dinosaur from the Early Jurassic of Patagonia and the Origin and Evolution of the Sauropod-type Sacrum

The dental and postcranial anatomy of Leonerasaurus supports its close affinities with basal sauropods, and shows that the characteristic sauropod body plan evolved gradually, with a step-wise pattern of character appearance.

Postcranial axial skeleton of Europasaurus holgeri (Dinosauria, Sauropoda) from the Upper Jurassic of Germany: implications for sauropod ontogeny and phylogenetic relationships of basal Macronaria

The postcranial axial skeleton of sauropods is extremely modified with respect to the anatomy observed in its ancestors, the ‘prosauropods’, proving to be one of the most informative regions of the body.

New Remains Attributable to the Holotype of the Sauropod Dinosaur Neuquensaurus australis, with Implications for Saltasaurine Systematics

Morphological differences in the number, shape, and proportion of sacral vertebrae allow discrimination between Neuquensaurus and Saltasaurus, confirming their generic separation.

Anatomical Terminology for the Sacrum of Sauropod Dinosaurs

The sacrum represents a key anatomical element for understanding Dinosauria, beginning with the first use of the taxon name in 1842. A five-vertebra sacrum was originally considered diagnostic of

Overosaurus paradasorum gen. et sp. nov., a new sauropod dinosaur (Titanosauria: Lithostrotia) from the late Cretaceous of Neuquén, Patagonia, Argentina.

Analysis of the phylogenetic relationships of Overosaurus places it within the Aeolosaurini, as the sister taxon of a monophyletic group formed by Aeolosaurus rionegrinus, A. maximus, Gondwanatitan faustoi and Pitekunsaurus macayai.

A New Sauropod: Tastavinsaurus Sanzi Gen. Et Sp. Nov. from the Early Cretaceous (Aptian) of Spain

In the cladistic analysis, Tastavinsaurus is the sister-taxon of the North American Venenosaurus within Titanosauriformes, which includes the Brachiosauridae, Somphospondyli, and Titanosaurusia.

Evolución de las vértebras presacras en Sauropodomorpha

It is demonstrated that the presacral vertebrae represent a rich source of information for understanding the evolution and systematics of sauropodomorphs, and it is proposed that the dicraeosaurid type might have evolved independently of other presacrals, the cetiosauridtype probably representing the ancestral condition.
