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

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

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
The presence of pneumatized sacral and caudal vertebrae in neosauropods indicates that abdominal air sacs were probably present in at least some sauropods.

A new sauropod dinosaur from the Early Cretaceous of Tunisia with extreme avian-like pneumatization

The Tunisian specimen shows a complex pattern of caudosacral and pelvic pneumatization--including the first report of an ischial pneumatic foramen among Dinosauria--strongly supporting the presence of abdominal air sacs.

A Basal Lithostrotian Titanosaur (Dinosauria: Sauropoda) with a Complete Skull: Implications for the Evolution and Paleobiology of Titanosauria

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
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.

Description of uncommon pneumatic structures of a noasaurid (Theropoda, Dinosauria) cervical vertebra to the Bauru Group (Upper Cretaceous), Brazil

Postcranial pneumaticity: An evaluation of soft‐tissue influences on the postcranial skeleton and the reconstruction of pulmonary anatomy in archosaurs

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

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
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.

The phylogenetic relationships of sauropod dinosaurs

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’.

A nomenclature for vertebral laminae in sauropods and other saurischian dinosaurs

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

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
