American shark teeth

I have a pretty good collection of Miocene

fossil shark teeth from North America(South Carolina).

Among them are parts of meg teeth, great white,

Isurus hastalis, Hemipristis serra and even Carcharinus obscurus.

They are practically all  black, only some are not.I have three practically full meg teeth. The biggest one is shown on the photo. Another tooth is lateral, and another small posterior. Also in this collection are two huge teeth halves - megalodon and Carcharocles chubutensis.

My strangest tooth is the one shown on the second photograph.         Megalodon tooth("meg")

 It's or Isurus hastalis or Great White. It has no serrations, like Isurus, but is shaped like  Carcharodon(I really prefer a Great White).

There some Hemipristis teeth with funny serrations! One is small, and another is relatively big(4-5 sm).

The most abundant fossils are teeth of Carcharodon and Carcharocles.
