Teensy long-necked dinosaur embryo reveals weird snout horn

I was born on a farm and we had chickens. We knew that it was common for baby chickens to scratch their way out of the eggshell when they hatched by using a small "horn" that grew out of the top of their beaks. This feature disappeared (don't know if it was reabsorbed or dropped off) soon after hatching, although one chicken we had went through her entire life with it still on top of her beak.
I'd imagine this dinosaur embryo had something similar.
