This is an exceptional upper jaw from the extinct bony fish Enchodus (Actinopterygii-ray-finned fish)

The opaque minerals represent the 17 % of the sample composed mostly of iron

although their absolute chemical composition is dependent on the physical and chemical properties of the usually granular-crystalline material providing an electrically and thermally conductive dissipation network for lightning-facilitated energy transfer
