bluegilldvm Posted May 1, 2023 Share Posted May 1, 2023 I found these while splitting some black shale collected at a private club in Grundy County. The first 3 pics are of one specimen and the last 2 are of another specimen but not as well preserved. Thanks. 1 Link to comment Share on other sites More sharing options...
