This is a real fossilized raptor (theropod dinosaur) egg! It was originally found in East Asia and was purchased from a Korean paleontology collection. It dates back roughly 75 million years and you can even see the preserved, "rippled" texture on the eggshell.
It is very likely that this egg hatched, or was preyed upon, due to the layering and positioning of the shell fragments.
We can ship this ~4" long specimen worldwide and it comes with a lifetime guarantee of authenticity.
