An exceptionally preserved Lower Cretaceous ecosystem
TLDR
Findings include feathered theropod dinosaurs and early birds, which provide additional, indisputable support for the dinosaurian ancestry of birds, and much new evidence on the evolution of feathers and flight.
Dinosaur diversity and the rock record
TLDR
Strong statistically robust correlations demonstrate that almost all aspects of ornithischian and theropod diversity curves can be explained by geological megabiases, whereas the sauropodomorph record diverges from modelled predictions and may be a stronger contender for identifying evolutionary signals.
A new hypothesis of dinosaur relationships and early dinosaur evolution
TLDR
This study has found a sister-group relationship between Ornithischia and Theropoda (united in the new clade Ornithoscelida), with Sauropodomorpha and Herrerasauridae (as the redefined Saurischia) forming its monophyletic outgroup.
A phylogenetic analysis of basal sauropodomorph relationships: Implications for the origin of sauropod dinosaurs2
TLDR
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.
The evolution of sauropod feeding mechanisms
TLDR
Sauropods were gigantic, long-necked, herbivorous dinosaurs, which dominated many Jurassic and Cretaceous terrestrial faunas, and the ‘aquatic’ hypothesis had an important effect on interpretations of sauropod feeding habits and mechanisms.
Homeotic effects, somitogenesis and the evolution of vertebral numbers in recent and fossil amniotes
TLDR
It is shown that the mammalian (synapsid) and reptilian lineages show early in their evolutionary histories clear divergences in axial developmental plasticity, in terms of both regionalization and meristic change, with basal synapsids sharing the conserved axial configuration of crown mammals, and basal reptiles demonstrating the plasticity of extant taxa.
Testing the effect of the rock record on diversity: a multidisciplinary approach to elucidating the generic richness of sauropodomorph dinosaurs through time
TLDR
Despite its distortion by sampling biases, much of sauropodomorph palaeobiodiversity can be interpreted as a reflection of genuine biological signals, and fluctuations in sea level may account for some of these diversity patterns.
Sauropod dinosaurs from the Lower Cretaceous of eastern Asia: taxonomic and biogeographical implications
Sauropod dinosaurs are poorly represented in the Lower Cretaceous of eastern Asia. Here, we describe a number of isolated sauropod teeth from the Kuwajima Formation (?Berriasian–?Hauterivian) of
