The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc(软体动物),
The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together
Dr Paul Butler, from the University’s School of Ocean Sciences, said: “We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we’ve got the right age now.” The mollusc was born in 1499 – just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509.
