Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs. [PDF]
J AnatA combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.

New titanosauriform (Dinosauria: Sauropoda) specimens from the Upper Cretaceous Daijiaping Formation of southern China [PDF]
PeerJ, 2019 Titanosauriform sauropod dinosaurs were once considered rare in the Upper Cretaceous of Asia, but a number of titanosauriforms from this stratigraphic interval have been discovered in China in recent years.

A new eusauropod (Dinosauria, Sauropodomorpha) from the Middle Jurassic of Gansu, China [PDF]
Scientific ReportsSauropod dinosaurs were gigantic quadrupedal herbivores. They range from Early Jurassic to Late Cretaceous and have been found on all continents. The rich sauropod faunas in the Middle and Late Jurassic of China are mainly from southern or western China.

Hypothetical lung structure of Brachiosaurus (Dinosauria: Sauropoda) based on functional constraints [PDF]
Fossil Record, 1999 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.

A specimen-level phylogenetic analysis and taxonomic revision of Diplodocidae (Dinosauria, Sauropoda) [PDF]
PeerJ, 2015 Diplodocidae are among the best known sauropod dinosaurs. Several species were described in the late 1800s or early 1900s from the Morrison Formation of North America.

A new species of early-diverging Sauropodiformes from the Lower Jurassic Fengjiahe Formation of Yunnan Province, China [PDF]
Scientific Reports, 2020 Sauropodomorpha were herbivorous saurischian dinosaurs that incorporate Sauropoda and early-diverging sauropodomorphs. The oldest sauropodomorph remains are known from Late Triassic deposits, most of them Gondwanan.

Osteology of Huabeisaurus allocotus (Sauropoda: Titanosauriformes) from the Upper Cretaceous of China. [PDF]
PLoS ONE, 2013 BackgroundThe Late Cretaceous titanosauriform sauropod Huabeisaurus allocotus Pang and Cheng is known from teeth and much of the postcranial skeleton. Its completeness makes it an important taxon for integrating and interpreting anatomical observations ...

A new mamenchisaurid from the Upper Jurassic Suining Formation of the Sichuan Basin in China and its implication on sauropod gigantism [PDF]
Scientific ReportsThe Sichuan Basin has yielded abundant sauropod dinosaurs from the Middle-Late Jurassic, and Mamenchisauridae had predominated the dinosaur faunae during the Late Jurassic in the Sichuan Basin.

Novel pneumatic features in the ribs of the sauropod dinosaur Brachiosaurus altithorax [PDF]
Acta Palaeontologica Polonica, 2023 Pneumatic dorsal ribs are known for many sauropods, but to date costal pneumaticity has received relatively little attention. In particular, the pneumatic ribs of the holotype specimen of Brachiosaurus altithorax have been largely overlooked, although ...
