66-Million-Year-Old Fully Articulated Dinosaur Embryo is Discovered Inside of a Fossilized Egg
Back in a land before time, many dinosaurs laid eggs. With parents guarding their clutches, tiny baby dinosaurs might eventually emerge from incubating embryos. Yet this process is only occasionally captured in the fossil record. Fossils of nesting dinosaurs atop eggs, or of complete egg embryos, are quite rare. However, a fully articulated dinosaur embryo was discovered inside a fossilized egg held by a Chinese museum, according to a paper published in iScience in 2021.
