The two mega-shark teeth in the images above are both from the Suwannee River. The first is pathological from damage to the tooth file in the shark's jaw. The second tooth is normal.

I would love to find something like this. I imagine these are quite rare. What do you think causes these? Trauma? Mineral deficiencies?

Often, it's a stingray barb lodged in the jaw, perhaps affecting two tooth files [anlagen].
