Neosauropods are well represented in the Late Jurassic fossil record, both in Laurasia and Gondwana. Among Macronaria, Europasaurus represents one of the most basal forms of this group. In addition to its systematic importance, Europasaurus is also the first unequivocal dwarf sauropod from which adult and juvenile material is available. Despite the abundance of sauropods in the fossil record, early juvenile specimens are rare, limiting knowledge about sauropod ontogeny. Therefore, the great… 

Cranial anatomy of the Late Jurassic dwarf sauropod Europasaurus holgeri (Dinosauria, Camarasauromorpha): ontogenetic changes and size dimorphism

TLDR
All the autapomorphic characters of Europasaurus recognized in the skull are considered to have evolved through paedomorphosis, which resulted in the dwarf condition of this taxon.

The appendicular skeleton of the dwarf macronarian sauropod Europasaurus holgeri from the Late Jurassic of Germany and a re-evaluation of its systematic affinities

TLDR
An extensive re-evaluation of the systematic position of Europasaurus was done based on the three most substantial data sets published in recent years, which resolvedEuropasaurus as a basal camarasauromorph in all cases, but brachiosaurid affinities remain plausible, especially considering the heterochronic evolution of the taxon.

Ontogenetic changes in the postcranial skeleton of Mussaurus patagonicus (Dinosauria, Sauropodomorpha) and their impact on the phylogenetic relationships of early sauropodomorphs

TLDR
The osteology of the postcranial skeleton of immature specimens of Mussaurus is presented, highlighting the main anatomical changes that occurred during its ontogeny and supporting the hypothesis of paedomorphic evolution in certain regions of the skeleton.

Postcranial Osteology of the First Early-Stage Juvenile Skeleton of Plateosaurus trossingensis (Norian, Frick, Switzerland)

TLDR
The observed morphology suggests that adult morphology was either achieved early in ontogeny of Plateosaurus, or alternatively that developmental plasticity, which has previously been found to result in high variability of adult body size, could potentially also extend to morphological development.

A new African Titanosaurian Sauropod Dinosaur from the middle Cretaceous Galula Formation (Mtuka Member), Rukwa Rift Basin, Southwestern Tanzania

TLDR
Both comparative morphology and phylogenetic analyses support Mnyamawamtuka as a distinct and distant relative to Rukwatitan bisepultus and Shingopana songwensis from the younger Namba Member of the Galula Formation with these results largely congruent with newly constrained ages for the Mtuka Member (Aptian–Cenomanian) and Namba Members (Campanian).

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

A juvenile Diamantinasaurus matildae (Dinosauria: Titanosauria) from the Upper Cretaceous Winton Formation of Queensland, Australia, with implications for sauropod ontogeny

ABSTRACT Although sauropod dinosaur bones are the most abundant vertebrate fossils found in the Upper Cretaceous Winton Formation of northeast Australia, only subadult and adult specimens have been

Osteological revision of the holotype of the Middle Jurassic sauropod dinosaur Patagosaurus fariasi Bonaparte, 1979 (Sauropoda: Cetiosauridae)

ABSTRACT Middle Jurassic sauropod taxa are poorly known, due to a stratigraphic bias of localities yielding body fossils. One such locality is Cerro Cóndor North, Cañadón Asfalto Formation,

A Basal Lithostrotian Titanosaur (Dinosauria: Sauropoda) with a Complete Skull: Implications for the Evolution and Paleobiology of Titanosauria

TLDR
A number of distinctive morphologies—such as the ossified cervical tendon, extremely pneumatized cervical vertebrae, and a habitually downward-facing snout—that have rarely, if ever, been documented in other titanosaurs are documented, thus broadening the understanding of the anatomical diversity of this remarkable sauropod clade.

Osteology and phylogenetic relationships of Tehuelchesaurus benitezii (Dinosauria, Sauropoda) from the Upper Jurassic of Patagonia

TLDR
The phylogenetic relationships of this taxon are tested through an extensive cladistic analysis that recovers Tehuelchesaurus as a non-titanosauriform camarasauromorph, deeply nested within Neosauropoda.

A New Sauropodomorph Dinosaur from the Early Jurassic of Patagonia and the Origin and Evolution of the Sauropod-type Sacrum

TLDR
The dental and postcranial anatomy of Leonerasaurus supports its close affinities with basal sauropods, and shows that the characteristic sauropod body plan evolved gradually, with a step-wise pattern of character appearance.

TLDR
The holotype of Andesaurus delgadoi is re-describe, comprising dorsal, sacral, and caudal vertebrae, as well as limb and pelvic elements, and putative titanosaur synapomorphies are recognized.

A NEW TITANOSAURIFORM SAUROPOD (DINOSAURIA: SAURISCHIA) FROM THE EARLY CRETACEOUS OF CENTRAL TEXAS AND ITS PHYLOGENETIC RELATIONSHIPS

  • P. Rose
  • Geography, Environmental Science
  • 2007
TLDR
The Texas sauropod does not possess synapomorphies of Somphospondyli, and derived characters that have been used to define the Titanosauria are also absent, affirming its placement as a basal titanosauriform.

The Osteology of Chubutisaurus insignis Del Corro, 1975 (Dinosauria: Neosauropoda) from the ‘Middle’ Cretaceous of Central Patagonia, Argentina

TLDR
The phylogenetic analysis presented here resolves Chubutisaurus as the most basal somphospondylian.

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).

TLDR
Phylogenetic results support a sister group relationship between the Asian Cretaceous sauropods Erketu and Qiaowanlong, erasing the evidence for the dispersal of Brachiosauridae into Asia.
