This fossil is easy to find on the beach anywhere between Redcar and Saltburn. Often known as a Devil’s Toenail.
It is a relative of they oyster and lived on the seabed in large numbers. This shell had two parts, one much larger than the other. Sometimes you find them still joined together.
You often see many lines on the shell. These are growth rings and you could guess how old the Gryphaea was before it died by counting them.
