Sauroposeidon proteles is a large brachiosaurid sauropod recently described from the Antlers Formation (Aptian-Albian) of southeastern Oklahoma. Sauroposeidon represents the culmination of brachiosaurid trends toward lengthening and lightening the neck, and its cervical vertebrae are characterized by extensive… 
The Early Evolution of Postcranial Skeletal Pneumaticity in Sauropodomorph Dinosaurs
TLDR
It is probable that rigid non-compliant lungs ventilated by compliant posterior air sacs evolved prior to the origination of Dinosauria, and the presence of pneumatic features within the infradiapophyseal fossae suggest that the homologous fossae of more basal saurischians and dinosauriforms were receptacles that housed pNEumatic diverticula.
A Nomenclature for Vertebral Fossae in Sauropods and Other Saurischian Dinosaurs
TLDR
The proposed nomenclatural system for lamina-bounded fossae adds clarity to descriptions of complex vertebrae and allows these structures to be sourced as character data for phylogenetic analyses.
THE EVOLUTION OF VERTEBRAL PNEUMATICITY IN SAUROPOD DINOSAURS
  • M. Wedel
  • Environmental Science, Biology
  • 2003
TLDR
The presence of pneumatized sacral and caudal vertebrae in neosauropods indicates that abdominal air sacs were probably present in at least some sauropods.
A Basal Lithostrotian Titanosaur (Dinosauria: Sauropoda) with a Complete Skull: Implications for the Evolution and Paleobiology of Titanosauria
TLDR
A number of distinctive morphologies—such as the ossified cervical tendon, extremely pneumatized cervical vertebrae, and a habitually downward-facing snout—that have rarely, if ever, been documented in other titanosaurs are documented, thus broadening the understanding of the anatomical diversity of this remarkable sauropod clade.
A NEW TITANOSAURIFORM SAUROPOD (DINOSAURIA: SAURISCHIA) FROM THE EARLY CRETACEOUS OF CENTRAL TEXAS AND ITS PHYLOGENETIC RELATIONSHIPS
  • P. Rose
  • Geography, Environmental Science
  • 2007
TLDR
The Texas sauropod does not possess synapomorphies of Somphospondyli, and derived characters that have been used to define the Titanosauria are also absent, affirming its placement as a basal titanosauriform.
Postcranial pneumaticity: An evaluation of soft‐tissue influences on the postcranial skeleton and the reconstruction of pulmonary anatomy in archosaurs
TLDR
An examination of regional pneumaticity in extant avians reveals remarkably consistent patterns of diverticular invasion of bone, and thus provides increased resolution for inferring specific components of the pulmonary air sac system in their nonavian theropod ancestors.
Bone Histology and Microanatomy of Alamosaurus sanjuanensis (Sauropoda: Titanosauria) from the Maastrichtian of Big Bend National Park, Texas
TLDR
Overall, Alamosaurus bone histology combines characteristics found in less derived sauropods, such as an early onset of secondary reconstruction, with novel characters such as extensively pneumatic ribs and longer retention of juvenile tissue.
Vertebral pneumaticity, air sacs, and the physiology of sauropod dinosaurs
  • M. Wedel
  • Environmental Science, Biology
    Paleobiology
  • 2003
TLDR
Air sacs and skeletal pneumaticity probably facilitated the evolution of extremely long necks in some sauropod lineages by overcoming respiratory dead space and reducing mass and may have conveyed some of the respiratory and thermoregulatory advantages enjoyed by birds, a possibility that is consistent with the observed rapid growth rates of sauropods.
Osteology of Barapasaurus tagorei (Dinosauria: Sauropoda) from the Early Jurassic of India
TLDR
Phylogenetic analysis reveals that Barapasaurus is basal in comparison with Vulcanodon and is removed from Eusauropoda.

SAUROPOSEIDON PROTELES, A NEW SAUROPOD FROM THE EARLY CRETACEOUS OF OKLAHOMA
Abstract Sauroposeidon proteles, a new brachiosaurid sauropod, is represented by an articulated series of four mid-cervical vertebrae recovered from the Antlers Formation (Aptian–Albian) of
Evolution of titanosaurid sauropods. I: phylogenetic analysis based on the postcranial evidence
TLDR
Titanosaurids more derived than Epachthosaurus sciuttoi Powell and Malawisaurus dixeyi Haughton have medial prespinal lamina formed down to the base of neural spine in posterior trunk vertebrae and quadrangular coracoids.

A Re-Evaluation of the Dry Mesa Dinosaur Quarry Sauropod Fauna with a Description of Juvenile Sauropod Elements
Abstract The Dry Mesa Dinosaur Quarry has produced the most diverse Morrison Formation dinosaur assemblage known, possessing twenty-three genera of dinosaurs, eight of which are sauropods. A
The phylogenetic relationships of sauropod dinosaurs
TLDR
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’.
EVOLUTION OF TITANOSAURID SAUROPODS. II: THE CRANIAL EVIDENCE
"The titanosaurid skull is interpreted as Camarasaurus-Iike, but with ""peg-like"" teeth restricted to the extremity of the jaws, which exhibit wear facets sharply inclined with respect to the
A nomenclature for vertebral laminae in sauropods and other saurischian dinosaurs
TLDR
A landmark-based nomenclature for sauropod vertebral laminae is proposed, which establishes the first criterion of homology (similarity), is the first step towards interpreting their phylogenetic significance.
The Evolutionary History of Sauropod Dinosaurs
TLDR
Forked chevrons, which have played such an important role in previous studies of sauropod phylogeny, are here considered to have evolved twice within the Sauropoda, which may reflect a correlation between chevron shape and the use of the tail as a weapon within these twosauropod families.
ALAMOSAURUS (DINOSAURIA: SAUROPODA) FROM THE LATE CAMPANIAN OF NEW MEXICO AND ITS SIGNIFICANCE
The titanosauridAlamosaurus sanjuanensis Gilmore, 1922, has long been known as the last North American sauropod; its fossils from Wyoming, Utah, New Mexico and Texas have been generally agreed to be
The phylogenetic relationships of the Nemegtosauridae (Saurischia, Sauropoda)
TLDR
Cladistic analysis supports the hypothesis that nemegtosaurid are the sister-group to a clade containing Rebbachisaurus, dicraeosaurids and diplodocids and the presence of the plesiomorphic state cannot be confirmed in higher titanosauroids.
