A rare fossilized egg from the extinct Elephant Bird goes to auction

Christie's London has put on display what is thought to be one of the largest eggs ever seen: a rare, fossilized egg from the extinct Elephant Bird.

The egg measures 30 centimeters high and 21 centimeters wide, and is expected to fetch up more than £30,000 when it is auctioned at the end of the month.

Experts with Christie's say Elephant Bird eggs are the largest the world has ever seen, even larger than those laid by dinosaurs. The enormous egg is about 120 times the size of an ordinary chicken egg

The Elephant Bird was the largest bird ever to have lived. Resembling a heavily-built ostrich, it was hunted to extinction. It is thought that this rare egg was discovered in the late 19th or early 20th century.

The egg will be auctioned off in London on April 24.
