Video: Auction of giant eggs

A rare, giant bird egg, believed to be the largest, is being auctioned in London.

The egg is produced by a native elephant bird in Madagascar, Africa. This is a flightless bird and extinct around the 13th to 17th centuries.

BBC quoted James Hyslop, a scientist at Christie's auction house, where the auctioned egg said: "This is the biggest egg ever. It's even bigger than a dinosaur egg."

The egg size is 100 times larger than the normal egg. It is 30cm long, 21cm in diameter. The egg can reach £ 30,000.
