Fossils

We found these on Shanklin beach. I believe they are petrified cockles that have been turned to stone. The loose ones came out of the larger piece which was from a lot larger rock to start with. I have wet the surface of them so they would be more visible in the shot.
The extra is of three pieces of petrified wood and two other pieces that I thought were interesting were a piece of rock that shows where some cockles have been and half a hollowed out rock.
