A clam’s long timescaleSourced
An age count revised to 507
Ming was an ocean quahog collected off Iceland in 2006. Its shell growth lines initially suggested 405 years, later revised to 507. The name referred to China’s Ming dynasty, not to where the clam was found.
Centuries were recorded inside a palm-sized shell.
