Titan Posted July 23, 2020 Share Posted July 23, 2020 Hi 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, Link to post Share on other sites
Petalodus12 Posted July 23, 2020 Share Posted July 23, 2020 Could possibly be vertebrate material, maybe fish skull material, but I’m not sure 1 Link to post Share on other sites
jdp Posted July 24, 2020 Share Posted July 24, 2020 Actinopterygian (ray-finned fish) parasphenoid. An actinopt expert might be able to ID it more definitely. 3 Link to post Share on other sites
