A New Nanoid Titanosaur (Dinosauria: Sauropoda) from the Upper Cretaceous of Brazil

Ameghiniana, 2022
. Titanosaurian sauropods are known to exhibit remarkable body size disparity, with some taxa famed for nearing the zenith of terrestrial vertebrate body size. Here, we describe a new titanosaurian – Ibirania parva gen. et sp. nov.

Titanosaurid (Sauropoda) osteoderms from the Late Cretaceous of Madagascar

Journal of Vertebrate Paleontology, 1998
ABSTRACT 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.

Historical Biology
Rebbachisauridae is mainly recorded during the early Late Cretaceous in Gondwana, and in South America in particular. Sidersaura marae gen. et sp. nov.

They all floated in the cretaceous: new rebbachisaurid (Sauropoda, Diplodocoidea) with a highly pneumatized skeleton from the Upper Cretaceous (lower Cenomanian) of Patagonia, Argentina

Historical Biology
Rebbachisaurids are a group of basal diplodocoid sauropods that diversified primarily in Gondwana between the early Lower Cretaceous and the early Upper Cretaceous.

The Axial Skeleton of Rinconsaurus caudamirus (Sauropoda: Titanosauria) from the Late Cretaceous of Patagonia, Argentina

Ameghiniana, 2022
. Titanosaurs were the predominant herbivores during the Late Cretaceous, inhabiting all continents. This clade was especially diverse in South America with some of the largest and smallest sauropod species known to date.

Early‐diverging Titanosauriform (Dinosauria, Sauropoda) Teeth from the Lower Cretaceous Yixian Formation of Southeastern Inner Mongolia, Northeast China

Acta Geologica Sinica (English)
Three eusauropod teeth (SDUST‐V1064, PMOL‐AD00176, PMOL‐ADt0005) are reported from the Lower Cretaceous Yixian Formation of Ningcheng, southeastern Inner Mongolia, China.

The phylogenetic relationships of the Nemegtosauridae (Saurischia, Sauropoda)

Journal of Vertebrate Paleontology, 1999
ABSTRACT 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 ...

Osteology of Dashanpusaurus dongi (Sauropoda: Macronaria) and new evolutionary evidence from Middle Jurassic Chinese sauropods

Journal of Systematic Palaeontology, 2022
The Middle Jurassic lower Shaximiao Formation in Sichuan Province of south-western China has yielded a diverse terrestrial vertebrate fauna dominated by sauropod dinosaurs.

The structural preservation of a titanosaurid (Dinosauria: Sauropoda) vertebral ligament

Cretaceous Research, 2016
Abstract 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

The dentary of Suuwassea emilieae (Sauropoda: Diplodocoidea)

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