Completely natural. Mother nature is a spectacular artisan. Limestone, sandstone and various sedimentary stone concretions are commonly mistaken for artifacts. Around here, I expect to see some of them in just about every new collection I look at. Here's a page showing a few examples of popular concretions - http://www.priweb.org/ed/concretions.htm
