Impressive specimen with the natural association of 2 brittlestars of the genus Ophiura

-The bend at the end of the tip is a specific trait of Pterosaur claws: The tip shows a thin flange or ridge of bone on the very tip on the ventral edge

03049 - Superb Pyritized 0.62'' Goniatites Devonian Cephalopod KemKem_Beds_Fish_Assemblage Impressive specimen with the naturalImpressive 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.
