The record breaking find is thought to have been laid by the Great Elephant Bird of Madagascar, a species last seen in 1658. It measures nearly half a metre in length, which is 180 times bigger than a normal chicken's egg. Auctioneers at Bonhams in London are hopeful that it will bj sold for over £30,000.  Contacts 176 PP Info 177 Sport 300 Next News Contacts PP Info PP Rjpts
