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] .

Until the 1980s, discoveries of fossilized eggs and bones of young dinosaurs were extremely rare, but dinosaur eggs have now been discovered on several continents, and fossils of hatchlings, juveniles, and adults have been found for most major groups.

2020年4月9日 · The world's oldest dinosaur eggs are helping us understand how baby dinosaurs grew. New high-powered scans of an early dinosaur species' fossilised eggs are showing for the first time how the animals' teeth developed while still inside the egg.

2021年3月18日 · Within 70-million-year-old rock deposits located in southern China's Jiangxi Province, researchers unearthed a preserved fossil of an oviraptorosaur crouched over a nest of 24 eggs, reports Alaa...

2021年12月21日 · Scientists have announced the discovery of a perfectly preserved dinosaur embryo that was preparing to hatch from its egg, just like a chicken. The embryo was discovered in Ganzhou in southern...

2023年3月21日 · Today’s paleontologists tend to agree that different dinosaur species laid different amounts of eggs. While some species produced around 1 to 5 in a single sitting, others produced around 15 to 20. Paleontologists have even discovered one type of dinosaur, the psittacosaurus, that laid around 35 eggs at a time.

2020年6月22日 · One study found evidence that some of the earliest dinosaurs laid soft-shelled eggs, and not eggs with hard shells as was previously thought. The second discovery is another soft-shelled egg that...

The structure of the eggs can help scientists figure out whether dinosaurs were more like birds or reptiles. And, in a very few cases, a fossilized egg can show paleontologists what a dinosaur embryo looked like.

real dinosaur eggs Now lets end by cheering ourselves up with some real dinosaur eggs. Remember, always look for eggshell ornamentation, cracks/deformities (there are perfect eggs out there, but they're very rare) and ask yourself, does it resemble any of the types of fakes we looked at above.

Fossil eggs and nests are the only evidence about the reproductive biology of dinosaurs. Eggs and nests are called indirect fossils because they are not real (direct) parts of the organism that produced them. However, only the nests must be regarded as trace fossils.
