A SPECTACULAR fossil specimen that suggests the presence of an avian type of nesting behaviour in oviraptorids, a clade of non-avian maniraptoran theropods, is reported here. The substantial evidence indicating that birds are a type of theropod dinosaur has led to copious discussion concerning the origin and possible presence of advanced avian reproductive behaviour in non-avian dinosaurs. Although the inference of behaviour from fossils is problematic, some remarkable discoveries, such as the…

Dinosaur eggs and nesting behaviors: A paleobiological investigation
TLDR
A review of Mesozoic saurischian egg materials, in comparison with extant crocodilians and avians, and their paleobiological interpretation based on the presence of embryos in ovo or brooding adults on egg clutches shows that many oological characters and reproductive behaviors associated with modern birds are rooted among non-avian theropods.
Exceptional preservation of a Late Cretaceous dinosaur nesting site from Mongolia reveals colonial nesting behavior in a non-avian theropod
Colonial nesting behavior has been inferred in a variety of non-avian dinosaurs based on high concentrations of nests preserved in an area, but sedimentologic and taphonomic evidence demonstrating…
Oldest known dinosaurian nesting site and reproductive biology of the Early Jurassic sauropodomorph Massospondylus
TLDR
A temporally calibrated optimization of dinosaurian reproductive biology not only demonstrates the primary significance of the Massospondylus nesting site, but provides additional insights into the initial stages of the evolutionary history of dinosaurs, including evidence that deposition of eggs in a tightly organized single layer in a nest evolved independently from brooding.
UNIQUE MANIRAPTORAN EGG CLUTCH FROM THE UPPER CRETACEOUS TWO MEDICINE FORMATION OF MONTANA REVEALS THEROPOD NESTING BEHAVIOUR
TLDR
This clutch reveals that the egg-layer of Montanoolithus strongorum had a unique suite of reproductive characteristics and nesting behaviours among maniraptorans.
Reconstruction of oviraptorid clutches illuminates their unique nesting biology
TLDR
It is indicated that the oviraptorid clutch has a unique architecture unknown from extant bird clutches, implying an apomorphic nesting mode, which supports the hypothesis that the clutch-associated ovirptorid adults possibly represent females after an oviposition before a catastrophic sandstorm/flooding burial.
Bird-like characteristics of troodontid theropod eggshell
TLDR
The identification of squamatic ultrastructure in troodontid eggshell, which was previously thought to lack this structure, reveals problems with the previous assignment of this eggshell to the dinosauroid-prismatic morphotype and with the concept of eggshell morphotype in the current eggshell parataxonomy.
Hatching Asynchrony in Oviraptorid Dinosaurs Sheds Light on Their Unique Nesting Biology
TLDR
The inferred hatching asynchrony in combination with previously surmised thermoregulatory incubation and communal nesting behaviors very likely suggests that oviraptorid dinosaurs presented a unique reproductive biology lacking modern analogs, which is contrary to the predominant view that their reproductive biology was intermediate between that of modern crocodiles and birds.
Oviraptor philoceratops Dinosaurs
Oviraptor philoceratops [2] was a small bird-like dinosaur that lived about seventy-five million years ago, during the late Cretaceous period. In 1923, George Olsen of the American Museum of Natural…
Incubation behaviours of oviraptorosaur dinosaurs in relation to body size
TLDR
The results suggest that the smallest oviraptorosaurs probably sat directly on the eggs, whereas with increasing body size more weight was likely carried by the central opening, reducing or eliminating the load on the Eggs and still potentially allowing for some contact during incubation in giant species.
RARE IN SITU PRESERVATION OF ADULT CROCODYLIAN WITH EGGS FROM THE MIDDLE EOCENE OF GEISELTAL, GERMANY
TLDR
A remarkable fossil of an adult crocodylian preserved in situ with eggs from the middle Eocene of Geiseltal, Germany is presented, providing the first-reported evidence for the antiquity of parental care in the croc Codylian lineage.

TLDR
Phylogenetic analysis of 60 taxa using parental-care data in combination with anatomical data shows that biparental care is primitive for birds, and that bipparental incubation arose from an ancestral condition in which neither parent incubated.
