Ying Baby, a 72 to 66 million years old duck-billed dinosaur embryo, 

was discovered inside a fist-sized fossil in East China. 

It is the most complete and the best-preserved embryo fossil ever scientifically recorded of its kind.

The size of the egg, with a diameter of roughly 9 centimeters, 

suggests that small eggs and late body development are the primitive traits of large herbivore dinosaurs with duck-like flat beaks. 

Ying Baby is currently housed in Yingliang Stone Natural History Museum, China.
