BobWill Posted August 19 Share Posted August 19 These came from the Late Pennsylvanian, Finis Shale member of the Graham Formation at Jacksboro Texas. Bottom right is likely to be an echinoid spine with that stereom-looking texture and the others may be conodonts or scolecodonts but I am not familiar enough with them to say. Any ideas? Scale is millimeters. 4 Link to comment Share on other sites More sharing options...
