Dinosaurs grew in the egg in a similar fashion to modern birds, a study suggests.

Scientists made the discovery after examining a cache of more than 200 fossilised bones from embryonic dinosaurs, all believed to belong to the same species, Lufengosaurus, a 26ft, long-necked sauropod.

The Early Jurassic fossils,
dating back 200 million years to the start of the dinosaurs’ reign, originated from several nests in southern China.

The embryos were at different stages of growth, allowing scientists to study how Lufengosaurus developed before hatching.
