Figure 10. The belemnite Neohibolithes from the Altmann–Member, Barremian, southwestern Altmann–Sattel, Alpstein Massif (Switzerland). Specimen NMSG Coll. P. Kürsteiner 5A.05.07.

Silicification rings on the surface of the rostrum. Specimen whitened with NH₄Cl. Note the thin silica crust with underlying original calcite (termed by some “shelter preservation”). Also, the centers are slightly fuzed which was never observed in our material.
