Extremely rare Notidanodon lanceolatus tooth from the Albian of Stary Oskol, Russia. A highly desirable Cretaceous Hexanchid (Cow Shark) tooth. Exceptional coloration on this specimen. This specimen is over 1" wide and is 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.
