How big is the pearl inside an oyster the size of your face? According to the Daily Mail, experts at the Blue Reef Aquarium in Portsmouth, England, are trying to determine just that.
An ancient oyster ten times larger than its modern counterparts could contain a golf ball sized pearl.
The 100 million-year-old fossil discovered off the British coast will undergo an MRI scan to see if contains what would likely be one of the largest pearls on record. "It was discovered in the nets of a fishing boat which was dredging here in the Solent," said a spokesman from the Blue Reef Aquarium.
"Oysters can be aged by annual growth rings on their shells and we have counted more than 200 rings on this oyster making it an extremely long-lived individual. It's obviously a million-to-one chance that it would contain anything but, if you were to go purely on the dimensions of the shell then you'd be looking at a golf ball-sized pearl."
