Digital reconstruction of the skull of Sarmientosaurus musacchioi, a titanosaur (Sauropoda, Dinosauria) from the Upper Cretaceous of Argentina

MorphoMuseuM
The study of titanosaur paleobiology has been severely hampered by the incomplete nature of their fossil record, particularly the scarcity of well-preserved and relatively complete cranial remains.

Histology of teeth and tooth attachment in titanosaurs (Dinosauria; Sauropoda)

Cretaceous Research, 2016
Abstract 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.

Osteological reassessment of Muyelensaurus pecheni (Dinosauria: Sauropoda): Systematics and its phylogenetic implications for the clade Rinconsauria

Historical Biology
Since its definition, Rinconsauria has been considered a titanosaurian clade more deeply nested than Lognkosauria and closely related to Aeolosaurini. However, some recent analyses include Lognkosauria within Rinconsauria, with other studies suggest that

The Appendicular Osteology ofPatagotitan Mayorum(Dinosauria, Sauropoda)

Journal of Vertebrate Paleontology, 2020
Its 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, 2014
ABSTRACTA 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.

A NEW AEOLOSAURINI (SAUROPODA, TITANOSAURIA) FROM THE UPPER CRETACEOUS OF URUGUAY

Ameghiniana
The Upper Cretaceous Guichón Formation (northwestern Uruguay) has yielded remains of notosuchian crocodyliforms, iguanodontian ornithopods, and saltasauroid titanosaurs.

Titanosaurian (Dinosauria: Sauropoda) remains from the “Continental Intercalaire” of Mali

Journal of Vertebrate Paleontology, 2004
Abstract We describe fragmentary new postcranial remains of a sauropod from “Continental Intercalaire” rocks of the Tilemsi Valley in northeastern Mali. Addition of this taxon to recently published cladistic analyses indicates that it is nested within Titanosauria and it is among the oldest members of this clade.

The lost fossil of the first discovered rebbachisaurid: reassessment of Nopcsaspondylus alarconensis (Diplodocoidea, Sauropoda)

Historical Biology
Rebbachisauridae is a group of diplodocoid sauropods mainly record from the Hauterivian to Turonian of Europe, Africa and South America. They were specifically abundant for the Cenomanian-Turonian times of Patagonia, Argentina.
