Aepyornis Eggs

The elephant bird or Aepyornis, originally found on the island of Madagascar, became extinct around 1700. But at least 19 eggs, belonging to the huge, flightless birds, were still around when the last survey was completed in 1933. And they’re bigger than the largest known dinosaur eggs, with a capacity of up to 2-1/2 gallons. That’s the equivalent of 180 large chicken eggs or seven ostrich eggs.
