A rare and complete sub-fossilized Elephant bird egg that is more than 100 times the size of an ordinary chicken egg is up for auction in London.
Elephant birds became extinct sometime between the 13th and 17th centuries. Resembling a heavily-built ostrich, it would have stood up to 11 feet high. It is thought the bird was hunted to extinction.
The complete, sub-fossilized egg is 12 inches high and 8 ¾ inches wide. It is expected to fetch roughly £30,000 ($45,000) when it is sold April 24.
