06481 - Great Collection of 4 Onchopristis numidus Cretaceous Sawfish Rostral Teeth Cretaceous Shark teeth bulk although their absolute chemical composition

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

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

The contrast between the root and the enameled crown is sharp and perfect

06481 - Great Collection of 4 Onchopristis numidus Cretaceous Sawfish Rostral Teeth Cretaceous Shark teeth bulk although their absolute chemical compositionGreat collection of 4 specimens. Some of them have glued and tiny filled fractures. Onchopristis is a genus of extinct giant sawfish that lived in the Lower Cretaceous to Upper Cretaceous in North Africa and New Zealand. It had an elongated snout lined laterally with barbed teeth. It is a large sawfish, known from remains throughout North America, North Africa and New Zealand. It was very large, up to 8 m (26. 2 ft) long when fully grown. As with
