A partial dinosaur skeleton from the Upper Triassic (Norian) sediments of South Africa is described and named Antetonitrus ingenipes. It provides the first informative look at a basal sauropod that was beginning to show adaptations towards graviportal quadrupedalism such as an elongated forelimb, a modified femoral architecture, a shortened metatarsus and a changed distribution of weight across the foot. These adaptations allowed the clade to produce the largest–ever terrestrial animals…

NEW INFORMATION ON LESSEMSAURUS SAUROPOIDES (DINOSAURIA: SAUROPODOMORPHA) FROM THE UPPER TRIASSIC OF ARGENTINA
TLDR
This assemblage of bones shows numerous derived characters, including some derived similarities exclusively shared with Antetonitrus ingenipes from the Upper Triassic of South Africa, and an unusual combination of plesiomorphic character states present in many non-eusauropod sauropodomorphs.
A New Basal Sauropodomorph Dinosaur from the Upper Elliot Formation (Lower Jurassic) of South Africa
ABSTRACT A new basal sauropodomorph dinosaur, Massospondylus kaalae sp. nov., is named on the basis of a partial skull from the upper Elliot Formation (Lower Jurassic) of the Herschel District,
A basal sauropod dinosaur from the Early Jurassic of Morocco
Embryos of an Early Jurassic Prosauropod Dinosaur and Their Evolutionary Significance
TLDR
Embryonic body proportions and an absence of well-developed teeth suggest that hatchlings of this dinosaur may have required parental care and suggests that the quadrupedal gait of giant sauropods may have evolved by retardation of postnatal negative allometry of the forelimbs.
A new transitional sauropodomorph dinosaur from the Early Jurassic of South Africa and the evolution of sauropod feeding and quadrupedalism
TLDR
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.
Solving a dinosaurian puzzle: the identity of Aliwalia rex Galton

TLDR
Eucnemesaurus fortis Van Hoepen 1920 from the Late Triassic of South Africa is demonstrated to be the senior synonym of the puzzling dinosaur taxon Aliwalia rex Galton 1985 and it supports the paraphyletic nature of the traditional ‘prosauropod’ assemblage.
Biology of the sauropod dinosaurs: the evolution of gigantism
TLDR
There is no evidence, however, that resource availability and global physicochemical parameters were different enough in the Mesozoic to have led to sauropod gigantism.
An elephant-sized Late Triassic synapsid with erect limbs
TLDR
The discovery of Lisowicia overturns the established picture of the Triassic megaherbivore radiation as a phenomenon restricted to dinosaurs and shows that stem-group mammals were capable of reaching body sizes that were not attained again in mammalian evolution until the latest Eocene.
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.

The discovery of an incomplete sauropod skeleton from the Late Triassic period of Thailand provides the first osteological evidence of pre-Jurassic sauropods and substantiates theoretical predictions that there was a fairly long period of sauro pod evolution during the Triassic.

TLDR
Morphological evidence presented here suggests a semi-tubular manus was an exaptation that ultimately functioned as a weight-distributing structure, and that this unique morphology may have been present in basal sauropods.
