The mollusc, named Ming, was calculated to be 405-years-old when scientists accidentally killed it by opening its shell. New calculations have now emerged that the original age of the quahog clam was actually 507-years-old when it died - a good 102 years older than estimated.

It means Ming, named after the Chinese dynasty, was born in 1499. Ming was found alive by climate change experts from Bangor University in north Wales on a trip dredging the seabeds of Iceland in 2006, 'Daily Mirror' reported.
