In the past, researchers have found egg-stealing dragon individuals lying on egg nests in Mongolia and the Gobi region of Inner Mongolia, but the lack of embryonic fossils in the nests has long been controversial.
" egg-stealing dragons already have 'asynchronous hatching', a more progressive hatching method in living birds. It can be said that dinosaurs' reproductive methods are far more complex than previously recognized. Xu Xing, co-author of the paper
