so this is one of the best preserved dinosaur embryos ever found and reported in science and because it is so well preserved we can observe its posture very clearly which allows us to compare it with other dinosaurs as well as modern birds after careful fossil preparation basically we see the whole skeleton very clearly although some body parts are still embedded inside the dinosaur egg and we can see very very clean and well preserved skull which doesn't have any teeth and this feature is actually it's very typical in oviraptorosaur and because of this feature we assigned and together with other anatomical features we assigned this specimen to oviraptorosaur so in modern day birds they have unique behavior called parking so starting from day 17 they will curl their body up with its head in between its legs and then on 18 day 19 day until day 20 they will start to move into final tucking posture that is putting their right wing on top of his head and this posture was suggested to help the birth stabilize when they try to crack the eggshell using its beak so and this behavior has long been thought unique to birth but now we see evidence in our fossil that even in number dinosaurs they might have the same type of prehatching behavior
