How would you like this massive egg for Easter? It was laid by an Elephant Bird which went extinct hundreds of years ago.
The egg is so huge you could fit about 120 chicken eggs inside.
Scientific specialist James Hyslop said: "The egg is the largest egg ever laid by any animal. They are bigger than dinosaur eggs."
The egg is up for auction in London and could fetch up to £30,000.
It might be a bit heavy for the Easter bunny to deliver for you though!
