It is very common to find fish vertebrae in the Cretaceous sites in the south of Morocco

This piece belongs with absolute certainty to a great raptor

04179 - Superb Pyritized 1.31 Inch Goniatites Devonian Cephalopod Bone_Claw to spot predators rather thanImpressive example of this Devonian cephalopod. It is naturally pyritized. It has undergone a taphonomic process of permineralization in Iron Sulfide (Pyrite). Permineralization is a process of fossilization in which mineral deposits form internal casts of organisms. The characteristic lines of suture of this cephalopod of the Paleozoic can be perfectly observed. Nice specimen.
