Sauropod dinosaur embryos from the Late Cretaceous of Patagonia
TLDR
The first known unequivocal embryonic remains of sauropod dinosaurs—the only known non-avian dinosaur embryos from Gondwana—are described from a nesting ground in the Upper Cretaceous stage of Patagonia, Argentina and it is proposed that these specimens belong to the same sauroPod species.
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).
EMBRYOS AND EGGS FOR THE CRETACEOUS THEROPOD DINOSAUR TROODON FORMOSUS
TLDR
Elongate and asymmetric eggs of the oospecies Prismatoolithus levis occur regularly in the Upper Cretaceous Two Medicine Formation of western Montana and show several aspects either shared or convergent with some birds, and further demonstrate the close relationship of Troodontidae and Aves.
LATE CRETACEOUS AVIAN EGGS WITH EMBRYOS FROM ARGENTINA
TLDR
This data indicates that the distribution of Carboniferous strata in the Northern Hemisphere has changed significantly in recent centuries, with the largest changes occurring in the western hemisphere during the Bronze and Iron Age.
Nest Structure for Sauropods: Sedimentary Criteria for Recognition of Dinosaur Nesting Traces
Abstract Six egg-filled depressions discovered in the Upper Cretaceous Anacleto Formation (Campanian) of Patagonia, Argentina, and interpreted as dinosaur nests, provide the only known evidence of
Avian Paternal Care Had Dinosaur Origin
TLDR
Paternal care in both troodontids and oviraptorids indicates that this care system evolved before the emergence of birds and represents birds' ancestral condition.
New Oviraptorid Embryos from Bugin-Tsav, Nemegt Formation (Upper Cretaceous), Mongolia, with Insights into Their Habitat and Growth
TLDR
Eggs containing well-preserved skeletons were collected from Bugin-tsav, an Upper Cretaceous locality in the Nemegt Formation, Ömnögov' Aimag, Mongolia, andBone histology indicates that all embryos were probably close to hatching, based on the degree of ossification and in comparison with ossified patterns in living birds.
Comparison of water vapor conductance in a titanosaur egg from the Upper Cretaceous of Argentina and a Megaloolithus siruguei egg from Spain
TLDR
This study indicates that at least some dinosaurs did not fully bury their eggs, and suggests that higher embryonic growth rates may have required incubation in a more open environment, where water conservation represented a more critical factor than in a buried clutch.
The First Dictyoolithus Egg Clutches from the Lishui Basin, Zhejiang Province, China
ABSTRACT Three clutches and eight additional eggs are described from the Upper Cretaceous Chichengshan Formation in the Lishui Basin of Zhejiang Province, China. The three clutches contain 6–18
