Haemodynamics in the Sauropoda
Nature, 1973THE order Sauropoda includes the largest quadrupeds ever known. They were as long as 30 m and weighed as much as 80 t (Brachiosaurus1). To maintain an adequate blood supply to the brain in animals of such enormous size2, physiological adaptation is essential.

Caudal pneumaticity in derived titanosaurs (Dinosauria: Sauropoda)
Cretaceous Research, 2017Among extant vertebrates, only birds have a respiratory system associated with pneumatic diverticula. However, several extinct clades also had pneumatic diverticula, including the sauropod dinosaurs. Among sauropods, Saltasaurini are characterized by extreme postcranial pneumaticity, which extends as far down the spinal column as the posterior caudal ...

Titanosaurid (Sauropoda) osteoderms from the Late Cretaceous of Madagascar
Journal of Vertebrate Paleontology, 1998ABSTRACT In 1896 Charles Deperet described a fauna of dinosaurs from the Upper Cretaceous (?Campanian) Maevarano Formation from the Mahajanga Basin of northwest Madagascar. Among the dinosaurs was a titanosaurid sauropod that he named Titanosaurus madagascariensis. He attributed to the titanosaurid a large, thick circular osteoderm.

The dentary of Suuwassea emilieae (Sauropoda: Diplodocoidea)
Journal of Vertebrate Paleontology, 2010Sauropod cranial elements, despite their rarity, contain a significant proportion of the known phylogenetically important character data (see Wilson, 2002; Upchurch et al., 2004).

The phylogenetic relationships of the Nemegtosauridae (Saurischia, Sauropoda)
Journal of Vertebrate Paleontology, 1999ABSTRACT The phylogenetic relationships of the Late Cretaceous Mongolian sauropods Nemegtosaurus and Quaesitosaurus are controversial. Previous studies have interpreted nemegtosaurids as members of the Diplodocoidea or Titanosauroidea. The conflicting character sets, which support these alternative hypotheses, are examined and critically evaluated ...

The structural preservation of a titanosaurid (Dinosauria: Sauropoda) vertebral ligament
Cretaceous Research, 2016Abstract Within the past decade exceptional preservation of original organic components have been reported from several dinosaurian families, including members of Sauropodomorpha. Here we document the partial preservation of a vertebral ligament in the dorsal and sacral series of a titanosaur. Unlike other cases of tissue preservation, this structure

Histology of teeth and tooth attachment in titanosaurs (Dinosauria; Sauropoda)
Cretaceous Research, 2016Abstract Dental histology of periodontal tissues (cementum, periodontal ligament and alveolar bone) has been studied in mammals, crocodylians and some basal tetrapods, but these structures have never been studied in titanosaur sauropods. The goal of this work was to study the structures of dental insertion in Titanosaurs.

The Appendicular Osteology ofPatagotitan Mayorum(Dinosauria, Sauropoda)
Journal of Vertebrate Paleontology, 2020Its huge size, excellent preservation, and completeness make Patagotitan mayorum a unique opportunity to explore the anatomy, paleobiological, and phylogenetic aspects linked to gigantism within Sa...

Developmental Failure of Segmentation in a Caudal Vertebra of Apatosaurus (Sauropoda)
The Anatomical Record, 2014ABSTRACTA vertebral element assigned to an Apatosaurus cf. ajax from the Late Jurassic Morrison Formation is described. The specimen exhibits an unusual morphology where two vertebrae are nearly seamlessly fused together, including the haemal arch that spans them. This morphology is thought be the result of a developmental abnormality.
