Titan posted a topic in Fossil IDHi All, I'm having trouble identifying what I have here. It's from the Upper Carboniferous - Pennsylvanian Stark shale. It is in a phosphorite nodule. Dimensions are 1.5 inch (3.81 cm) long by 1 inch (2.54 cm) wide. Any ideas would be appreciated. Apologies for the green tint - not sure what that is except for maybe the camera picking up the radiation from this shale layer . Thanks,
