ABSTRACT The cranial anatomy of the basal sauropodomorph Coloradisaurus brevis from the upper levels of the Norian Los Colorados Formation is here redescribed and comparisons made based on the holotype skull and mandible. Coloradisaurus brevis is diagnosed by most of the features proposed in the original description and an additional set of autapomorphies, such as presence of circular upper temporal fenestrae, laminae on the ventrolateral margins of a ventral fossa of the basisphenoid and on… 
Skull remains of the dinosaur Saturnalia tupiniquim (Late Triassic, Brazil): With comments on the early evolution of sauropodomorph feeding behaviour
TLDR
A principal co-ordinates analysis of the sauropodomorph jaw feeding apparatus shows marked shifts in morphospace occupation in different stages of the first 30 million years of their evolutionary history, suggesting that, despite also having an omnivorous diet, the feeding behaviour of some early Carnian sauro podomorphs was markedly different from that of later Triassic taxa.
Redescription of the Cranium of Jingshanosaurus xinwaensis (Dinosauria: Sauropodomorpha) from the Lower Jurassic Lufeng Formation of Yunnan Province, China
TLDR
A better understanding of Jingshanosaurus will allow for reconstruction of the ecomorphotypic diversity of the Lower Jurassic Lufeng dinosaurs and help to decipher the origin and early evolution of sauropodiforms, the clade ultimately leading to the gigantic sauropods.
Ngwevu intloko: a new early sauropodomorph dinosaur from the Lower Jurassic Elliot Formation of South Africa and comments on cranial ontogeny in Massospondylus carinatus
TLDR
Ngwevu intloko, a new genus of upper Elliot basal sauropodomorph is named on the basis of a complete skull and partial skeleton previously assigned to Massospondylus carinatus, which reveals that BP/1/4779 had nearly reached adult size at the time of its death at a minimum age of 10 years.
New material and revision of Melanorosaurus thabanensis, a basal sauropodomorph from the Upper Triassic of Lesotho
TLDR
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.
A revised cranial description of Massospondylus carinatus Owen (Dinosauria: Sauropodomorpha) based on computed tomographic scans and a review of cranial characters for basal Sauropodomorpha
TLDR
This work digitally reconstructs the bones of the facial skeleton, braincase, and palate of a complete, undistorted cranium of M. carinatus (BP/1/5241) and hypothesizes 27 new cranial characters useful for determining relationships in non-sauropodan Sauropodomorpha, delete five pre-existing characters and revise the scores of several existing Cranial characters to make more explicit homology statements.
New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: is there more than one species?
TLDR
New skull material from Frick is described including eight complete and six partial skulls, more than doubling the number of known skulls of P. trossingensis and includes the first known juvenile skulls of Plateosaurus, allowing for detecting ontogenetic changes.
Braincase anatomy of the early sauropodomorph Saturnalia tupiniquim (Late Triassic, Brazil)
ABSTRACT The braincase anatomy of the sauropodomorph dinosaur Saturnalia tupiniquim from the Upper Triassic (Carnian) Santa Maria Formation of Brazil is described for the first time using computed
Craniomandibular osteology of Macrocollum itaquii (Dinosauria: Sauropodomorpha) from the Late Triassic of southern Brazil
  • R. Müller
  • Biology, Environmental Science
    Journal of Systematic Palaeontology
  • 2019
TLDR
A detailed description of the craniomandibular anatomy of M. itaquii is presented, based on the holotype, a paratype and a newly referred specimen, to elucidate the transition from slender basal sauropodomorphs to more robust derived members within this group.
Cranium and Vertebral Column of Xingxiulong chengi (Dinosauria: Sauropodomorpha) from the Early Jurassic of China
TLDR
A detailed osteological description of the axial skeleton of Xingxiulong chengi, including both the cranial and postcranial elements, is provided, and its anatomy is compared with that of other known non‐sauropodan sauropodomorphs.
Morphological Diversity and Evolution of the Jugal in Dinosaurs
TLDR
The conspicuous jugal ornaments seen in many ornithischian dinosaurs, like the less striking ones documented in some saurischians, may have played an important role in the social behavior of the species that possessed them, adding to the evidence that agonistic behavior was likely widespread among Ornithischians in particular.

TLDR
A detailed re-description of the cranial osteology of Yunnanosaurus huangi Young, 1942 is presented and an emended diagnosis for this taxon is proposed on the basis of numerous autapomorphic characters (including an expanded internarial bar, unusual midline cranial bosses, and the possession of elongate maxillary tooth crowns lacking marginal serrations).

This study supports referral of AMNH FARB 6810 to P. erlenbergiensis on the basis of the following characters: occipital condyle above level of parasphenoid; basisphenoid with transverse, subvertical lamina extending between basipterygoid processes; and peglike process projecting medially from the middle of the palatine.
