The Early Cretaceous was a time of dramatic change for sauropod dinosaurs in North America. Between the Late Jurassic-aged Morrison Formation and overlying Early Cretaceous strata, there was a dramatic decline in sauropod diversity. Here, we describe a new sauropod that adds to the diversity of the Early Cretaceous, from strata that can be no older than the early Aptian, (125 Ma) some 25 million years younger than the Morrison Formation. Moabosaurus utahensis, n. gen., n. sp., is diagnosed in… 
Cranial anatomy of Bellusaurus sui (Dinosauria: Eusauropoda) from the Middle-Late Jurassic Shishugou Formation of northwest China and a review of sauropod cranial ontogeny
Bellusaurus sui is an enigmatic sauropod dinosaur from the Middle-Late Jurassic Shishugou Formation of northwest China. Bellusaurus is known from a monospecific bonebed preserving elements from more
Descendants of the Jurassic turiasaurs from Iberia found refuge in the Early Cretaceous of western USA
TLDR
These recent discoveries in Utah suggest that turiasaurs as a lineage survived the Jurassic-Cretaceous extinction boundary and expanded their known range, at least, into western North America.

TLDR
Although turiasaurs show clear heterodont dentition, only broad, characteristically ‘heart’-shaped teeth can currently be attributed to Turiasauria with confidence, and accordingly, several putative turiasaur occurrences based on isolated teeth from Europe, as well as the Middle Jurassic and Early Cretaceous of Africa, cannot be confidently referred to Turiaauria.
Redescription of Brachiosaurid Sauropod Dinosaur Material From the Upper Jurassic Morrison Formation, Colorado, USA
TLDR
It is estimated that B. altithorax had a slower tooth replacement rate than Camarasaurus or the diplodocoids it shared Morrison Formation landscapes with, which suggests a difference in diet and/or feeding strategy.
Origin and evolution of turiasaur dinosaurs set by means of a new ‘rosetta’ specimen from Spain
TLDR
A new specimen of Losillasaurus from Spain is described, which allows us to better understand the character variation in the cranial and postcranial skeleton of Turiasauria, and suggests that this clade might have arisen in the Middle Jurassic.
The first dinosaurs from the Early Cretaceous Hami Pterosaur Fauna, China
TLDR
Besides the pterosaur Hamipterus and one theropod tooth, these dinosaurs are the first vertebrates reported in this region, increasing the diversity of the fauna as well as the information on Chinese sauropods, further supporting a widespread diversification of somphospondylans during the Early Cretaceous of Asia.
Osteology of Klamelisaurus gobiensis (Dinosauria, Eusauropoda) and the evolutionary history of Middle–Late Jurassic Chinese sauropods
TLDR
Anatomical comparisons of the cervical vertebrae of Klamelisaurus to several other sauropodomorphs and insights from myological studies of extant archosaurs strongly suggest that this latter structure is an epaxial muscle scar that is distinct from pneumatic structures of the lateral surface of the neural spine.
Sauropod teeth from the Middle Jurassic of Madagascar, and the oldest record of Titanosauriformes
Here we describe 31 fossil teeth, deposited in the palaeontological collections of the Museo di Storia Naturale di Milano (MSNM), that come from the inland portion of the Mahajanga Basin, NW

Abstract Sauroposeidon proteles, a new brachiosaurid sauropod, is represented by an articulated series of four mid-cervical vertebrae recovered from the Antlers Formation (Aptian–Albian) of
A NEW, LARGE ORNITHOMIMID FROM THE CRETACEOUS DINOSAUR PARK FORMATION OF ALBERTA, CANADA: IMPLICATIONS FOR THE STUDY OF DISSOCIATED DINOSAUR REMAINS
TLDR
How isolated dinosaur bones can extend the knowledge of dinosaur faunas is demonstrated, with a number of ornithomimid elements from Alberta's Dinosaur Park Formation cannot be assigned to either Ornithomimus or Struthiomimus.
NEW CRETACEOUS BRACHIOSAURID DINOSAUR, SONORASAURUS THOMPSONI GEN, ET SP. NOV, FROM ARIZONA
TLDR
The specimen described herein shows some clear brachiosaurid homologies that are both distinctly different from Pleurocoelus and from brachesaurids phylogenetically closer to the type Upper Jurassic Brachiosaurus, and a new taxonomic designation at the genus level is warranted.
First complete sauropod dinosaur skull from the Cretaceous of the Americas and the evolution of sauropod dentition
TLDR
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.
Revision of the sauropod dinosaurs of the Lower Cretaceous Trinity Group, southern USA, with the description of a new genus
TLDR
Cladistic analysis indicates that Astrophocaudia and Sauroposeidon are members of Somphospondyli, whereas Cedarosaurus is a brachiosaurid.
The Anatomy and Phylogenetic Relationships of “Pelorosaurus“ becklesii (Neosauropoda, Macronaria) from the Early Cretaceous of England
TLDR
Phylogenetic analysis confirms that Haestasaurus becklesii is a macronarians, but different data sets place this species either as a non-titanosauriform macronarian, or within a derived clade of titanosaurs that includes Malawisaurus and Saltasauridae.
The Beginning of the Sauropod Dinosaur Hiatus in North America: Insights from the Lower Cretaceous Cloverly Formation of Wyoming
ABSTRACT We redescribe and present newly excavated sauropod material from the Lower Cretaceous Cloverly Formation of Wyoming that we refer to the titanosauriform Sauroposeidon proteles. In contrast
Osteology of the Late Jurassic Portuguese sauropod dinosaur Lusotitan atalaiensis (Macronaria) and the evolutionary history of basal titanosauriforms
TLDR
The results support the generic separation of the contemporaneous taxa Brachiosaurus, Giraffatitan, and Lusotitan, with the latter recovered as either a brachiosaurid or the sister taxon to Titanosauriformes.
Redescription and reassessment of the phylogenetic affinities of euhelopus zdanskyi (Dinosauria: Sauropoda) from the early cretaceous of China
TLDR
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).
Postcranial axial skeleton of Europasaurus holgeri (Dinosauria, Sauropoda) from the Upper Jurassic of Germany: implications for sauropod ontogeny and phylogenetic relationships of basal Macronaria
TLDR
The postcranial axial skeleton of sauropods is extremely modified with respect to the anatomy observed in its ancestors, the ‘prosauropods’, proving to be one of the most informative regions of the body.
