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 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.

A path to gigantism: Three-dimensional study of the sauropodomorph limb long bone shape variation in the context of the emergence of the sauropod bauplan. [PDF]
J Anat, 2022 Our study investigates the limb long bone shape variation of a large sample of sauropodomorph dinosaurs in the context of the emergence of the sauropod bauplan. We highlight a differential emergence of sauropod‐related features, that appear abruptly in the forelimb bones and more gradually in the hindlimb ones.

Palaeobiology and osteohistology of South African sauropodomorph dinosaurs. [PDF]
J AnatWe found that the transitionary Sauropodiformes show both the traits of rapid growth of derived Sauropoda as well as interrupted growth of early branching Sauropodomorpha. There appears to be much more variation in growth dynamics of Sauropodiformes than initially thought.

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs. [PDF]
Anat Rec (Hoboken)Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.

II.—On the Diplodocidæ, a New Family of the Sauropoda; an Order of American Jurassic Dinosaurs [PDF]
Geological Magazine, 1884 The Sauropoda are now generally recognized by anatomists as a well-marked order of the Sub-class Dinosauria. In the previous articles of this series, the main characters of the two families of this order (Atlantosauridæ and Morosauridæ) already named by the writer have been given.3 A third family is represented by the genus Diplodocus, a study of which,

A new gigantic titanosaurian sauropod from the early Late Cretaceous of Patagonia (Neuquén Province, Argentina) [PDF]
Acta Palaeontologica Polonica, 2023 A new gigantic titanosaur Bustingorrytitan shiva gen. et sp. nov. is described. The four specimens upon which this species is erected come from Neuquén Province, Argentina, from levels of the Huincul Formation (Cenomanian).

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 ...

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.
