Many suspect that the woods were once covered in water, pointing to such rocks as evidence.
I have an alternate theory.
I suspect that life originally developed on land, where, you will notice, things are much less damp and conducive to advancing in the conga line of life. These rocks display terran ancestors to the creatures presently found in the seas. They were likely forced into the water to seek out new sources of food.
