Graywacke Imprints

Recently I noticed some interesting imprints in the graywacke at John Brown’s Beach. As best I can tell, something that was formerly there is no longer there, and that something was different than the rest of the rock. Perhaps it was some sort of softer stone embedded in the harder graywacke that eroded easily? I was also intrigued by the shapes, and am wondering if I could get a positive look at it with silly putty or something.
