SCARCE Prionace glauca (Blue Shark) tooth from the Pliocene Pisco Formation of Sacaco, Peru. Due to their pelagic habits, Prionace teeth are extremely rare to find fossilized. All natural with no repairs or restoration.
 
Private Vault specimens are hand-picked from my personal collection, and are stand-out fossils based on exceptional rarity, condition, coloration, etc., or a combination of such traits, making them very difficult to obtain.
