An embryonic skeleton of a nonavian theropod dinosaur was found preserved in an egg from Upper Cretaceous rocks in the Gobi Desert of Mongolia. Cranial features identify the embryo as a member of Oviraptoridae. Two embryo-sized skulls of dromaeosaurids, similar to that of Velociraptor, were also recovered in the nest. The eggshell microstructure is similar to that of ratite birds and is of a type common in the Djadokhta Formation at the Flaming Cliffs (Bayn Dzak). Discovery of a nest of such… Expand

Unusual Theropod Eggshells from the Early Cretaceous Blesa Formation of the Iberian Range, Spain
Trigonoolithus amoae oogen. et oosp. nov. is described on the basis of abundant eggshell fragments from the La Cantalera 1 site in the Early Cretaceous (early Barremian) Blesa Formation, TeruelExpand
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. Expand
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. Expand
Palaeontology: Pterosaur embryo from the Early Cretaceous
TLDR
A Chinese fossil from the Early Cretaceous period containing an embryo that is unambiguously a pterosaur is described, confirming that pterosaurs were egg-layers and sheds new light on the understanding of pterOSaur development. Expand
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.

Dinosaur Eggs Associated with Crustacean Trace Fossils from the Upper Cretaceous of Jiangxi, China: Evidence for Foraging Behavior?
TLDR
The seven dinosaurian eggs reported clearly belong to the Elongatoolithidae and burrow traces were most likely made by small crustaceans, prompting the question as to whether invertebrate activity had relations with the buried eggs. Expand
Viviparity in a Triassic marine archosauromorph reptile
Eggs or embryos have been reported in various groups of fossil reptiles, where viviparity is a common mode of reproduction in aquatic taxa such as the ichthyopterygians, some groups ofExpand

Bird-like characteristics of the jaws and teeth of troodontid theropods (Dinosauria, Saurischia)
TLDR
A critical examination of all jaws and teeth attributed to Troodon, Stenonychosaurus, and Pectinodon concluded that Troodon is the senior synonym of these genera, and that the name Troodontidae has priority over Saurornithoididae. Expand

Congenital hereditary hypothyroidism—prenatal diagnosis and treatment
TLDR
Experienced experience indicates that testing of amniotic fluid for TSH in the 22nd week of gestation can be diagnostic for congenital primary hypothyroidism, and it is suggested that the treatment approach described is warranted in all cases in which there is a high risk of congenitalPrimary hypothyroxine.

TLDR
The reduced catalytic activity of the -Gly49-psi(COS)-Ile50-backbone-engineered enzyme analogue provides direct experimental evidence to support the suggestion that backbone hydrogen bonds from the enzyme flaps to the substrate are important for the catalytic function of the HIV-1 protease. Expand
