Bone Daddy Posted July 24, 2019 Share Posted July 24, 2019 I received some rough material that is labeled as Mahantango Formation, Middle Devonian : Givetian, McCoy's Ferry, Maryland. The stone has some strange circular impressions on it. I have no idea what these are. Can anyone tell me what these impressions are? Thanks in advance!
