Heart and Head Holey Stones

There is a particular part of the beach between Lundin Links and Lower Largo, where if tide and sand conditions are right, can find stones with holes in them. These holes are naturally made by rock boring molluscs such as a piddock. This heart shaped stone is one of the most unusual that I've found.

Would have thought it impossible for a stone to look startled, until I saw this one on the beach. Note all the tiny barnacles on the top of the stone and the surrounding rocks.

The two holes in this little stone immediately suggest a face. A slight case of pareidolia.
