**************************** Shark teeth, in being shed or bring torn out during feeding, may have been hit by other teeth in the shark's mouth. This might have occurred by another tooth grazing the unexpelled, shed tooth as the shark closed it's mouth. The damage appears as straight, shallow, parallel scratches at odd angles to the enamel hydration cracking which occur during fossilization. These scratches are caused by serrations on another tooth and are generally very fine occurring in rows of about 50 per inch. Another type of damage occurs when the tip of another tooth comes down perpendicular on to the blade of a shed tooth and leaves a distinctive "V' shaped groove. See photos below. The 4 irregular deep gouges in the first photo and the edge damage in the second were caused by tips of other teeth while the shallow parallel scratches in the first photo were caused by a single tooth's serrated blade edge.
Fossilized prey animal bones and vertebra also exhibit these teeth marks. (See whale vertebra photos below.)
Another scenario could be that the tooth became imbedded in the prey animal during feeding and was bitten during a subsequent bite. (We have some teeth that appear to have made the journey completely through the shark's digestive system. These teeth have uniform corrosion to blade and root as if bathed in acid.)
