As far as we know, all dinosaurs hatch from eggs, including extinct dinosaurs and modern birds! Shared behaviors like these are evidence of common ancestry. And today, scientists use observations of living relatives to breathe life into animals that have been extinct for millions of years. #stem #museumtok #paleontology #dinosaurs #creatorsearchinsights

Fossils of dinosaur eggs rarely have bones inside them. In 1993, however, museum scientists found an egg in the Gobi Better that contained the remains of a tiny dinosaur embryo from 80,000,000 years ago. This was the first non avian theropod embryo ever found, and you can see a cast of it on the museum's 4th Floor. The fossilized egg was discovered as part of a weathering nest of eggs. The egg was already broken open rank exposing the bones of a curled up oviraptorid embryo within. Uncurled, the embryo would measure about eight inches in length. By studying specimens like this, paleontologists are able to draw two conclusions. One, oviraptor and closely related dinosaurs had an advanced system of parental care. And two, many behaviors seen in modern bad, such as sitting on the nest, evolved earlier in the history of dinosaurs and were inherited by birds.
