Background The origin of sauropod dinosaurs is one of the major landmarks of dinosaur evolution but is still poorly understood. This drastic transformation involved major skeletal modifications, including a shift from the small and gracile condition of primitive sauropodomorphs to the gigantic and quadrupedal condition of sauropods. Recent findings in the Late Triassic–Early Jurassic of Gondwana provide critical evidence to understand the origin and early evolution of sauropods. Methodology… 

A new basal sauropod from the pre-Toarcian Jurassic of South Africa: evidence of niche-partitioning at the sauropodomorph–sauropod boundary?

Key changes in the dentition, axial skeleton and forelimb of this new species suggest a genuine functional distinction occurring at the sauropodiform-sauropod boundary, which may partially explain the rarity of true sauropods in the basal rocks of the Jurassic.

A new basal sauropodiform from South Africa and the phylogenetic relationships of basal sauropodomorphs

Sefapanosaurus, together with other transitional sauropodomorphs reported during the last decade, highlights the importance of Gondwanan taxa for understanding the palaeobiodiversity, global distribution, and macroevolutionary changes in the group related to the rise of sauropods.

Reassessment of Unaysaurus tolentinoi (Dinosauria: Sauropodomorpha) from the Late Triassic (early Norian) of Brazil, with a consideration of the evidence for monophyly within non-sauropodan sauropodomorphs

Although strong anatomical evidence for monophyletic divergences amongst early sauropodomorphs remains elusive, the relatively low stratigraphical occurrence of Unaysaurus demonstrates that the typical ‘prosauropod’ bauplan – and hence habitual herbivory – had evolved by the early Norian.

The postcranial anatomy of Coloradisaurus brevis (Dinosauria: Sauropodomorpha) from the Late Triassic of Argentina and its phylogenetic implications

New postrcanial remains of Coloradisaurus brevis, the most gracile sauropodomorph from this unit, are described here and evaluated within a phylogenetic context, indicating strong character support for the inclusion of ColorAdisaurus and Lufengosaurus within Massospondylidae.

A new dinosaur with theropod affinities from the Late Triassic Santa Maria Formation, south Brazil

Nhandumirim waldsangae shows that some typical theropod characters were already present early in dinosaur evolution, and it represents possibly the oldest record of the group known in Brazil.

Postcranial Anatomy and Phylogenetic Relationships of Mussaurus patagonicus (Dinosauria, Sauropodomorpha)

The postcranial anatomy of four specimens of basal sauropodomorphs from the Late Triassic of Patagonia, Argentina are described and identified as adult individuals of Mussaurus patagonicus, which is recovered as a non-sauropod anchisaurian and is depicted outside the ‘quadrupedal clade’.

Osteological Redescription of the Late Triassic Sauropodomorph Dinosaur Thecodontosaurus antiquus Based on New Material from Tytherington, Southwestern England

ABSTRACT Thecodontosaurus antiquus is a basal sauropodomorph from the Rhaetian locality of Durdham Down in Bristol, U.K. Sauropodomorph material putatively assigned to this species was found at the

A derived sauropodiform dinosaur and other sauropodomorph material from the Late Triassic of Canton Schaffhausen, Switzerland

Although sauropodomorph dinosaurs have been known for a long time from the Late Triassic of central Europe, sauropodomorph diversity and faunal composition has remained controversial until today.

Postcranial axial skeleton of Europasaurus holgeri (Dinosauria, Sauropoda) from the Upper Jurassic of Germany: implications for sauropod ontogeny and phylogenetic relationships of basal Macronaria

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.

New material and revision of Melanorosaurus thabanensis, a basal sauropodomorph from the Upper Triassic of Lesotho

The holotype femur of Melanorosaurus thabanensis is redescribed from the Elliot Formation of Lesotho, as well as associated remains, and the first phylogenetic analysis including both this specimen and Melanosaurus is conducted, leading to the conclusion that the femur described in the original publication can no longer be referred to Melanoriansaurus.



Anatomy of a basal sauropodomorph dinosaur from the Early Jurassic Hanson Formation of Antarctica

The anatomy of a basal sauropodomorph (Dinosauria: Saurischia) from the Early Jurassic Hanson Formation of Antarctica is described in detail and preliminary phylogenetic analyses suggest a close relationship between the new Antarctic taxon and Lufengosaurus.

A new transitional sauropodomorph dinosaur from the Early Jurassic of South Africa and the evolution of sauropod feeding and quadrupedalism

Cursorial ability appears to have been reduced and the weight bearing axis of the pes shifted to a medial, entaxonic position, falsifying the hypothesis that entaxony evolved in sauropods only after an obligate quadrupedal gait had been adopted.

Anatomy and phylogenetic relationships of Tazoudasaurus naimi (Dinosauria, Sauropoda) from the late Early Jurassic of Morocco

The complete osteology of the basal sauropod Tazoudasaurus naimi from the late Early Jurassic Toundoute continental series of Ouarzazate Province, Morocco, is presented. The described material

The species taxonomy of the sauropodomorph dinosaurs from the Löwenstein Formation (Norian, Late Triassic) of Germany

It was found that two discrete taxa comprise the current hypodigm of Sellosaurus, the more common form of which is a plesiomorphic form for which the correct name is Efraasia minor comb and is placed in this genus as Plateosaurus gracilis.


The results of this preliminary analysis indicate that Lamplughsaura is either a basal Sauropoda or, less likely, based on Templeton's test, a stem sauropodomorph.

A phylogenetic analysis of basal sauropodomorph relationships: Implications for the origin of sauropod dinosaurs2

The most parsimonious trees suggest that Efraasia, Mussaurus, Thecodontosaurus and Saturnalia are increasingly more distant sister-taxa to the remaining sauropodomorphs, while character mapping indicates several apomorphic features that support the monophyly of a plateosaurian clade or subgroups within it.

A revision of the problematic sauropodomorph dinosaurs from Manchester, Connecticut and the status of Anchisaurus Marsh

A revised cladistic analysis continues to find support for Anchisaurus as a relatively derived basal sauropodomorph that lies outside of the clade Melanorosaurus + Sauropoda but is more closely related to it than to ‘core prosauropods’ such as Plateosaurus and Massospondylus.

Anchisaurus polyzelus (Hitchcock): The Smallest Known Sauropod Dinosaur and the Evolution of Gigantism among Sauropodomorph Dinosaurs

Optimization of femur length using square change parsimony indicates that the lineage leading to Neosauropoda underwent gradual and sustained size increase for most of its history since its divergence from Theropoda and that A. polyzelus represents a reversal of this trend and has decreased in size relative to the sauropod common ancestor.


Abstract Re-examination of the surviving specimens of Thecodontosaurus antiquus indicates that this plesiomorphic sauropodomorph can be diagnosed on the basis of elongate basipterygoid processes, a

Skull anatomy of Mussaurus patagonicus (Dinosauria: Sauropodomorpha) from the Late Triassic of Patagonia

The skull anatomy of Mussaurus patagonicus from the Upper Triassic Laguna Colorada Formation is described based on a revision of the type material and several recently found specimens, revealing major changes in the rostral and temporal regions.
