Fossilized sauropod eggs displayed at Indroda Dinosaur and Fossil Park. Dinosaur eggs are the organic vessels in which a dinosaur embryo develops. When the first scientifically documented remains of non-avian dinosaurs were being described in England during the 1820s, it was presumed that dinosaurs had laid eggs because they were reptiles. [1]
Model of a dinosaur egg. Dinosaur reproduction shows correlation with archosaur physiology, with newborns hatching from eggs that were laid in nests. [1] [2] Dinosaurs did not nurture their offspring as mammals typically do, and because dinosaurs did not nurse, it is likely that most dinosaurs were capable of surviving on their own after hatching.

The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records, measures 45-by-20 millimeters (about 1.77-by-0.79 inches). Discovered in Japan's Tamba City, this ...
For decades, Compsognathus was known as the smallest known non-avian dinosaur, [5] although some dinosaurs discovered later, such as Mahakala and Microraptor, were even smaller. [ 25 ] [ 26 ] The German specimen was estimated to be 70–75 cm (28–30 in) [ 5 ] and 89 cm (35 in) [ 3 ] in length by separate authors, while the larger French ...
Macroelongatoolithus is an oogenus of large theropod dinosaur eggs, representing the eggs of giant caenagnathid oviraptorosaurs. They are known from Asia and from North America. Historically, several oospecies have been assigned to Macroelongatoolithus, however they are all now considered to be a single oospecies: M. carlylensis.
Baby Yingliang (YLSNHM01266) is a remarkably preserved dinosaur embryo discovered in Ganzhou, southern China. It was discovered in rock layers of the Hekou Formation, which dates to the Late Cretaceous. The embryo belongs to an oviraptorid theropod dinosaur, and the egg is classified as elongatoolithid.
Ark: Survival Evolved (stylized as ARK) is a 2017 action-adventure survival video game developed by Studio Wildcard. In the game, players must survive being stranded on one of several maps filled with roaming dinosaurs , fictional fantasy monsters, and other prehistoric animals, natural hazards, and potentially hostile human players.
Fossilized dinosaur eggs displayed at Indroda Dinosaur and Fossil Park. Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil. Under rare circumstances a fossil egg may preserve the remains of the once-developing embryo ...
