Due to their abundance, taxonomic and morphological diversity, wide range of body sizes and broad geographical distribution, titanosaurian sauropods were one of the most important Cretaceous herbivorous dinosaur groups. Consequently, titanosaurs constitute one of the best samples in which to evaluate the relationship between bony structures and unpreserved soft-tissues within Sauropoda. We reconstruct the morphology and interpret the implications of selected soft-tissues associated with the…

Vouivria is a basal brachiosaurid, confirming its status as the stratigraphically oldest known titanosauriform, and implementation of sensitivity analyses, in which these characters are excluded, has no effect on tree topology or resolution.

This reconstruction helps to elucidate the timing of important modifications of the appendicular musculature in the evolution of sauropodomorphs which facilitated the transition to quadrupedalism and contributed to their evolutionary success.

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…
Re-assessment of the Late Jurassic eusauropod dinosaur Hudiesaurus sinojapanorum Dong, 1997, from the Turpan Basin, China, and the evolution of hyper-robust antebrachia in sauropods
- Geography, Environmental Science
- 2021
Phylogenetic analyses confirm that Hudiesaurus is a CMT and the sister taxon of Xinjiangtitan, and links the convergent evolution of robust antebrachia and an enlarged olecranon in CMTs, titanosaurs, and some ornithischians to a more flexed orientation of the forearm, an enhanced role for the forelimb in locomotion, and an anterior shift in the whole-body center of mass.
Temporal and phylogenetic evolution of the sauropod dinosaur body plan

Three-dimensional computational models and phylogenetic reconstructions are combined to quantify the evolution of whole-body shape and body segment properties across the sauropod radiation, finding that relative neck size and CoM position are not strongly correlated with inferred feeding habits.

A good part of the postcranial skeleton of an Albian-Cenomanian primitive titanosaurid from Patagonia is described and discussed, and it is argued that the latter were endemic and very diversified, representing the major herbivorous group of the Late Cretaceous fauna of Gondwana.

The resulting contractile force and torque estimates presented here indicate a sizable investment in locomotive muscle among theropods with a range of body sizes and give new evidence in favor of greater athleticism, in terms of overall cursoriality, balance, and turning agility.

The results suggest that there are dangers inherent in the view that ‘higher’ level sauropod phylogeny can be accurately reconstructed using only a small number of well-known taxa, and that the results of the randomization tests indicate that the data-matrix probably contains a strong phylogenetic ‘signal’.
