revasius Posted January 14, 2017 Share Posted January 14, 2017 I found this piece several years ago in the Calvert Formation, MD. It has a hole that appears to be drilled through it. Is this a trace fossil, natural occurrence in bone or man made? Regards, Rich Link to comment Share on other sites More sharing options...

flyg Posted January 14, 2017 Share Posted January 14, 2017 I will toss out the possibility of a banner stone, a human artifact. I'm not very knowledgeable about these artifacts, but the fine, regular through-hole and general shape suggests possibly a banner stone that has been broken and/or worn in a high-energy surf zone or river. This is just an idea to check out. I've seen a few examples of stones and half-stones from rivers in coastal SC, but I'm a complete novice at paleontology and archaeology.
