A new caudipterid from the Lower Cretaceous of China with information on the evolution of the manus of Oviraptorosauria [PDF]

open access: yesScientific Reports, 2019
AbstractCaudipteridae is a basal clade of Oviraptorosauria, all known species from the Early Cretaceous Jehol Biota of northeastern China. They were one of the first feathered dinosaur groups discovered, and possessed avian-like pennaceous remiges and rectrices.

Oviraptorosauria: Morphology, Phylogeny, and Endocranial Evolution [PDF]

open access: yes, 2011
Oviraptorosauria, an extinct lineage of coelurosaurian dinosaurs from the Cretaceous of Asia and North America, includes some of the most morphologically distinctive theropod taxa yet known. Their bizarre appearance and numerous skeletal similarities with extant birds instantly made oviraptorosaurs the subject of considerable interest when first ...

Birdlike growth and mixed-age flocks in avimimids (Theropoda, Oviraptorosauria). [PDF]

open access: yesSci Rep, 2019
AbstractAvimimids were unusual, birdlike oviraptorosaurs from the Late Cretaceous of Asia. Initially enigmatic, new information has ameliorated the understanding of their anatomy, phylogenetic position, and behaviour. A monodominant bonebed from the Nemegt Formation of Mongolia showed that some avimimids were gregarious, but the site is unusual in the ...

The first ornithomimosaur remains from Germany [PDF]

open access: yesActa Palaeontologica Polonica
Ornithomimosauria is a group of coelurosaurs primarily known from the Cretaceous of Asia and North America. The European record is comparatively sparse, with Pelecanimimus from the Lower Cretaceous of Spain being the only unequivocal representative. Here,

New material ofChirostenotes pergracilis(Theropoda, Oviraptorosauria) from the Campanian Dinosaur Park Formation of Alberta, Canada [PDF]

open access: yesHistorical Biology, 2020
The taxonomy of caenagnathids from the Dinosaur Park Formation of Alberta, Canada, has remained problematic because of incomplete, partial skeletons that do not overlap anatomically.

Cranial Anatomy of Citipati osmolskae (Theropoda, Oviraptorosauria), and a Reinterpretation of the Holotype of Oviraptor philoceratops [PDF]

open access: yesAmerican Museum Novitates, 2002
We describe the skull of the holotype of Citipati osmolskae, one of the best preserved oviraptorid skulls known. The skull preserves stapes and epipterygoids, and the mandible preserves a slender coronoid bone, none of which has been reported before in oviraptorids.

Elongatoolithid eggs containing oviraptorid (Theropoda, Oviraptorosauria) embryos from the Upper Cretaceous of Southern China [PDF]

open access: yesBMC Evolutionary Biology, 2016
Oviraptorids, like many other dinosaurs, clearly had a complex pattern of skeletal growth involving numerous morphological changes. However, many ontogenetic skeletal changes in oviraptorids were previously unclear due to the lack of well preserved specimens that represent very young developmental stages.Here we report three elongatoolithid dinosaur ...

Anatomy, systematics, and evolution of Oviraptorosauria (Dinosauria, Theropoda)

open access: yes, 2019
Here I describe new oviraptorosaur specimens and add to our knowledge of the anatomy, growth, behaviour, ecology, and evolution of oviraptorosaurs. Oviraptorosaurs were a diverse group of theropods known from a long history of discovery and a relatively abundant fossil record. Most analyses divide the toothless members of the clade into three families:

Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs. [PDF]

open access: yesJ Anat
A combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.
