Sauropod dinosaur phylogeny: critique and cladistic analysis
A lower-level phylogenetic analysis of Sauropoda is presented, which resolves six sauropod outgroups to Neosauropoda, which comprises the large-nostrilled clade Macronaria and the peg-toothedclade Diplodocoidea. Expand
Early Evolution and Higher-Level Phylogeny of Sauropod Dinosaurs
The cladistic analysis presented here focuses on higher-level relationships among sauropods, and identifies Neosauropoda as a new taxon that includes Haplocanthosaurus, Camarasaurus, and Titanosauriformes. Expand
A nomenclature for vertebral laminae in sauropods and other saurischian dinosaurs
A landmark-based nomenclature for sauropod vertebral laminae is proposed, which establishes the first criterion of homology (similarity), is the first step towards interpreting their phylogenetic significance. Expand
Predatory Dinosaurs from the Sahara and Late Cretaceous Faunal Differentiation
Late Cretaceous (Cenomanian) fossils discovered in the Kem Kem region of Morocco include large predatory dinosaurs that inhabited Africa as it drifted into geographic isolation. One, represented by aExpand
Structural Extremes in a Cretaceous Dinosaur
Skeletal and dental evidence suggests that Nigersaurus was a ground-level herbivore that gathered and sliced relatively soft vegetation, the culmination of a low-browsing feeding strategy first established among diplodocoids during the Jurassic. Expand
New dinosaurs link southern landmasses in the Mid–Cretaceous
Fossils from three stratigraphic levels in the Cretaceous of Niger provide definitive evidence that abelisauroid dinosaurs and their immediate antecedents were also present on Africa and provide key evidence for continued faunal exchange among Gondwanan landmasses until the end of the Early Cret Jurassic.

Redescription of the mongolian sauropod nemegtosaurus mongoliensis nowinski (dinosauria: Saurischia) and comments on late cretaceous sauropod diversity
Synopsis The isolated skulls of Nemegtosaurus mongoliensis and Quaesitosaurus orientalis from the Nemegt Basin of Mongolia are among the most complete sauropod cranial remains known from the LateExpand
Redescription and reassessment of the phylogenetic affinities of euhelopus zdanskyi (Dinosauria: Sauropoda) from the early cretaceous of China
The results suggest that there were at least two clades of very long‐necked sauropods in East Asia, occurring in the Middle Jurassic (i.e. Omeisaurus + Mamenchisaurus) and Early Cretaceous (e.g. Euhelopus, Erketu), with the latter group perhaps also occurring in Europe (Canudo et al. 2002). Expand
First complete sauropod dinosaur skull from the Cretaceous of the Americas and the evolution of sauropod dentition
The first complete sauropod skull from the Cretaceous of the Americas is described, Abydosaurus mcintoshi, known from Dinosaur National Monument, USA, and may signal a shift towards elevated tooth replacement rates and high-wear dentition. Expand
Titanosaurs and the origin of wide-gauge trackways; a biomechanical and systematic perspective on sauropod locomotion
It is argued that skeletal morphology is respon- sible for gauge differences and integrate data from locomotor biomechanics and systematics with the track record to predict the hindlimb morphology of wide-gauge trackmakers, implying that titanosaurs were unique among sauropods in having a more varied repertoire of locomotor habits.
