Abstract The vertebrae of sauropod dinosaurs are characterized by complex architecture involving laminae, fossae, and internal chambers of various shapes and sizes. These structures are interpreted as osteological correlates of a system of air sacs and pneumatic diverticula similar to that of birds. In extant birds, diverticula of the cervical air sacs pneumatize the cervical and anterior thoracic vertebrae. Diverticula of the abdominal air sacs pneumatize the posterior thoracic vertebrae and… 

Postcranial Pneumaticity in Dinosaurs and the Origin of the Avian Lung

TLDR
The Air Space Proportion (ASP) is proposed as a measure of proportional volume of air in pneumatic bones, and indicates that increases in the number of cervical vertebrae, their proportional lengths, and their internal complexity occurred in parallel in most of these lineages.

Pneumatic structures in the cervical vertebrae of the Late Jurassic Tendaguru sauropods Brachiosaurus brancai and Dicraeosaurus

Abstract.The presacral vertebrae of sauropod dinosaurs were surrounded and invaded by a complex system of pneumatic diverticula, which originated most probably from cervical air sacs connected with

Evidence for bird-like air sacs in saurischian dinosaurs.

TLDR
Several lines of evidence suggest that air sac-driven lung ventilation was primitive for Saurischia, and anatomical and evolutionary patterns of pneumatization in nonavian saurischian dinosaurs are diagnostic for specificAir sacs, including the cervical, clavicular, and abdominal air sacs.

Caudal Pneumaticity and Pneumatic Hiatuses in the Sauropod Dinosaurs Giraffatitan and Apatosaurus

TLDR
The erratic patterns of caudal pneumatization in Giraffatitan and Apatosaurus show that pneumatic diverticula were more broadly distributed in the bodies of the living animals than are their traces in the skeleton.

Mechanical implications of pneumatic neck vertebrae in sauropod dinosaurs

TLDR
It is expected that vertebral pneumaticity in other parts of the body to have a similar role in enabling gigantism as it did in sauropods.

Pneumaticity and soft-tissue reconstructions in the neck of diplodocid and dicraeosaurid sauropods

TLDR
Comparisons between the vertebrae of juvenile and adult diplodocids strongly indicate that pneumatisation proceeded from the supramedullary diverticula into the neural arch and the neural spine, and the regular branching pattern of the pneumatic cavities as well as the vertical I−beam construc− tion of the vertebral corpora is interpreted as a consequence of the biomechanical constraints of the spine.

Soft-Tissue Evidence for Pneumatization in the Cervical Column of the Ostrich (Struthio camelus) and Observations on the Vertebral Columns of Non-Volant, Semi-Volant and Semi-Aquatic Birds. PLoS

TLDR
Pneumatic features in the vertebral column of 11 avian taxa, including the flightless ratites and selected members of semi-volant and semi-aquatic Neornithes, are tabulate and it is found that the mere presence of vertebral laminae does not indicate the presence of skeletal pneumaticity.

Vertebral pneumaticity of the North American therizinosaur Nothronychus

TLDR
The vertebrae of Nothronychus are intermediate between Allosaurus and Dinornis, and it is inferred to have possessed avian‐like abdominal air sacs, but this character cannot be related to endothermy.

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

Postcranial pneumatization in Archaeopteryx

TLDR
Two specimens of Archaeopteryx are re-examine and show evidence of vertebral pneumaticity in the cervical and anterior thoracic vertebrae, thus confirming the phylogenetic continuity between the pNEumatic systems of non-avialan theropods and living birds.

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.

TLDR
It is shown that the London specimen also has pneumatized anterior thoracal vertebrae, and, thus, that this feature was present in the most archaic avialans, as the London and Eichstätt specimens are different species.

Hypothetical lung structure of Brachiosaurus (Dinosauria: Sauropoda) based on functional constraints

TLDR
Comparison of avian and crocodylian lung structure suggests a basic archosaurian structural type, consisting of four rows of chambers that radiate independently from an intrapulmonary bronchus, which is cartilage-reinforced cranially and the cartilage reinforcement diminishes and the radiating pattern of tubular chambers becomes irregular.

An anatomical study of the respiratory air sacs in ostriches

TLDR
The air sacs of the ostrich conform to the general pattern in birds and are similar to those of other bird species, with the exception that humeral diverticula are absent.

TLDR
The presence of apparent osteological correlates of postcranial pneumaticity is reported in some non-crown-group archosaurs, and some of the fossil taxa more closely related to crocodilians than to birds, which suggests that the last common ancestor of birds and crocodilian might have had a pneumatized postCranium.

The rate of development of pneumatisation in the humerus was more rapid in White Leghorn pullets than in cockerels and also more rapid than in Golden Comet pullets.
