The articulated postcranial skeleton of an oviraptorid dinosaur (Theropoda, Coelurosauria) from the Late Cretaceous Djadokhta Formation of Ukhaa Tolgod, Mongolia, is preserved overlying a nest. The eggs are similar in size, shape, and ornamentation to another egg from this locality in which an oviraptorid embryo is preserved, suggesting that the nest is of the same species as the adult skeleton overlying it and was parented by the adult. The lack of a skull precludes specific identification… 
An Embryonic Oviraptorid (Dinosauria: Theropoda) from the Upper Cretaceous of Mongolia
TLDR
The skeleton of an embryonic oviraptorid skeleton described within an egg from the Late Cretaceous Djadokha Formation of Ukhaa Tolgod, Mongolia suggests that this species was closer to the precocial-altricial spectrum of developmental patterns than living Aves.
A New Specimen of Pinacosaurus grangeri (Dinosauria: Ornithischia) from the Late Cretaceous of Mongolia: Ontogeny and Phylogeny of Ankylosaurs
TLDR
The occurrence of a juvenile ankylosaur from the Upper Cretaceous locality Ukhaa Tolgod in southern Mongolia is reported, indicating that extensive morphological variability exists in the narial anatomy of P. grangeri.
Chicken-sized oviraptorid dinosaurs from central China and their ontogenetic implications
TLDR
The comparison of the measurements of 115 skeletons indicates that oviraptorids maintain their hind limb proportions regardless of ontogenetic stage or absolute size, which is a pattern seen more commonly in herbivores than in carnivores.
New Specimens of Nemegtomaia from the Baruungoyot and Nemegt Formations (Late Cretaceous) of Mongolia
TLDR
Nemegtomaia represents the fourth known genus of oviraptorid for which individuals have been found on nests of eggs and is found in both arid/aeolian (Baruungoyot Formation) and more humid/fluvial (NemEGt Formation) facies.
A new oviraptorid (Dinosauria: Theropoda) from the Upper Cretaceous of Bayan Mandahu, Inner Mongolia
Abstract:  A new oviraptorid is described on the basis of a partial forelimb collected from the Upper Cretaceous redbeds of Bayan Mandahu, Inner Mongolia. Machairasaurus leptonychus, gen. et sp. nov.
A New Caenagnathid (Dinosauria: Oviraptorosauria) from the Horseshoe Canyon Formation of Alberta, Canada, and a Reevaluation of the Relationships of Caenagnathidae
TLDR
Phylogenetic analysis resolves the complicated relationships of Caenagnathidae and allows the evolution of display features to be traced throughout Oviraptorosauria.
Postcranial skeletal anatomy of the holotype and referred specimens of Buitreraptor gonzalezorum Makovicky, Apesteguía and Agnolín 2005 (Theropoda, Dromaeosauridae), from the Late Cretaceous of Patagonia
TLDR
The holotype is the most complete specimen yet found, so an exhaustive description of it provides much valuable anatomical information, and a revised phylogenetic analysis recovered Buitreraptor as an unenlagiine dromaeosaurid, in agreement with previous works.
Cranial Anatomy of Citipati osmolskae (Theropoda, Oviraptorosauria), and a Reinterpretation of the Holotype of Oviraptor philoceratops
TLDR
Comparison of the new skull with the poorly preserved skull of the holotype of Oviraptor philoceratops demonstrates that the braincase and palate of the latter are similar to those of other oviraptorids, suggesting it may be the most basal ovIRaptorid.
NEW INFORMATION ON SEGISAURUS HALLI, A SMALL THEROPOD DINOSAUR FROM THE EARLY JURASSIC OF ARIZONA
Abstract Here we redescribe the holotype and only specimen of Segisaurus halli, a small Early Jurassic dinosaur and the only theropod known from the Navajo Sandstone. Our study highlights several
Elongatoolithid eggs containing oviraptorid (Theropoda, Oviraptorosauria) embryos from the Upper Cretaceous of Southern China
TLDR
The first known oviraptorid embryos associated with pathological eggshells are reported from the Upper Cretaceous Nanxiong Formation of Nankang District, Ganzhou City, Jiangxi Province, China that contain in ovo embryonic skeletons, and the absence of structural and histological abnormalities indicates the environmental factor that led to the eggshell pathologies did not affect the skeletal development of the ovirptorids themselves.

On the presence of furculae in some non-maniraptoran theropods
TLDR
DINO 11541 is closely related to Allosaurus and the presence of a furcula suggests that Allosaurus also had afurcula and that elements previously described as Allosaurus gastralia from the Cleveland-Lloyd Dinosaur Quarry are actually a growth series of furculae.
Nest and egg clutches of the dinosaur Troodon formosus and the evolution of avian reproductive traits
TLDR
Non-avian coelurosaurians possess several primitive features found in crocodilians and several derived features shared with birds (relatively larger and potentially asymmetric eggs, one egg produced per oviduct at a time, loss of egg retention, open nests, brooding).

On the discovery of an oviraptorid skeleton on a nest of eggs at Bayan Mandahu, Inner Mongolia, People's Republic of China
A partial skeleton of Oviraptor (which means egg thief), collected at Bayan Mandahu (Inner Mongolia, People's Republic of China) in 1990 was lying on top of a nest of eggs. Of the six known skeletons
The presence of a furcula in tyrannosaurid theropods, and its phylogenetic and functional implications
TLDR
A rerun of Bryant and Russell's (1993) congruence test was conducted against a new and larger tree reflecting new ideas about theropod phylogeny, and results more consistently show that clavicles are primitively present in theropods.
Evolutionary and Systematic Significance of Crocodilian Nesting Habits
TLDR
There are absolute differences in these nesting habits and, as I hope to show, these differences are also closely correlated with the evolution and systematics of the group.
Classification of fossil eggshells of amniotic vertebrates
TLDR
About 18 groups of fossil eggshells referred to turtles, geckoes, crocodiles, and to 14 "families" or dinosaur and bird oological remains are described and their composition, occurence, paleobiology and systematics are shortly presented.
Fossil mammals from the "Mesaverde" Formation (late Cretaceous, Judithian) of the Bighorn and Wind River basins, Wyoming : with definitions of late Cretaceous North American land-mammal "ages".
TLDR
Comparisons suggest that the Judithian mammalian fauna of what was then coastal parts of the western interior was essentially homogeneous geographically, at least from southern Alberta to central Wyoming, and Judithian mammal faunas of the Rocky Mountains must be younger in age.
