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 inside, in which case it also contains body fossils .
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 ...
The formation of fossil eggs begins with the original egg itself. Not all eggs that end up fossilizing experience the death of their embryo beforehand. Even eggs that successfully hatch can fossilize. In fact, not only is this possible it's actually common. Many fossil dinosaur eggs are preserved with their tops broken open by the escaping ...

The Gannanoolithus holotype specimen, YLSNHM 01579, consists of a clutch of eight eggs. Specimens CUGW EH067-1 (a single egg) and EH067-2 (a pair of eggs) were also referred to the oogenus. All of the known fossil eggs have been found in layers of the Lianhe Formation in the Shahe Industrial Zone of Ganzhou City in Jiangxi Province, China. The ...
Reptile egg fossils are the fossilized remains of eggs laid by reptiles. The fossil record of reptile eggs goes back at least as far as the Early Permian . However, since the earliest reptile eggs probably had soft shells with little preservation potential , reptilian eggs may go back significantly farther than their fossil record.
Antarcticoolithus is an oogenus of large fossil eggs from the Maastrichtian part of the Lopez de Bertodano Formation of Seymour Island, Antarctica. The genus contains the type species A. bradyi, described by Legendre et al. in 2020. [1] The fossil egg, the first found in Antarctica, was discovered in 2011 by a Chilean team of researchers.
