Recently acquired this rare 185mm nuchal bone from Dunkleosteus Terrelli, just thought to share it since there are very few Dunkleosteus material on the commercial market! Attached pictures below just to see the size of this since on most fish it's the size of your thumbnail! Devonian Cleveland Shale Cleveland, Ohio USA 185mm (7.2 inches) nuchal bone
