An gigantic oyster fossil that was trawled up by fisherman has been MRI   scanned to reveal what could be a pearl as large as a golf ball.

The mollusc was given to an aquarium where experts used growth rings to   determine how old it was, and were keen to discover if there was a rare gem   inside.

The medical charity Cobalt, which provides state of the art scanning services,   heard of the prehistoric find and volunteered to scan the oyster.

The scan showed a mysterious smooth object about the size of a golf ball   inside the 145-million-year-old shell.

If it were removed and identified as a pearl, it could be worth many thousands   of pounds.

But experts have decided not to explore the contents any further because the   oyster would have to be destroyed.
