wellwellwell Posted March 5, 2019 Share Posted March 5, 2019 Hello, i have a small bone fragment found on a beach on the James river in Virginia. It is very dense and all of the grain seems to generate from a central point. At first it seems like a fragment of a vertebra, but comparing to others I have found it seems different. Curious to see if anyone has any other ideas, thanks for your time, Link to comment Share on other sites More sharing options...
