Fossilized Dinosaur eggs displayed at Indroda Dinosaur and Fossil Park. This timeline of egg fossils research is a chronologically ordered list of important discoveries, controversies of interpretation, taxonomic revisions, and cultural portrayals of egg fossils. Humans have encountered egg fossils for thousands of years. In Stone Age Mongolia, local peoples fashioned fossil dinosaur eggshell ...
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]
Philip Kerourio debunked Erben and others' suggestion that an increase in the incidence of pathological eggs in dinosaurs led to their extinction. He found that only 0.5–2.5% of eggs in the area Erben and the others studied had multiple shell layers and observed no evidence that these pathologies became more common through the Late Cretaceous ...
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 ...
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 ...

Paleontologists found 100 eggs and 80 skeletons from a dinosaur called Mussaurus at a site in Patagonia, suggesting the animals lived in groups.
These small eggs (measuring 77–123 mm (3.0–4.8 in) long) are similar to the eggs of oviraptorid dinosaurs (oofamily Elongatoolithidae), but have a distinctive type of ornamentation. Continuoolithus nests would have been incubated under vegetation and sediment, unlike nests of Troodon and oviraptorids, which were incubated by brooding adults.
