Shark Tooth ID

[marfijak]

Hello, 

I have been collection shark teeth and other coastal fossils for some time now. Only recently have I developed an interest in identifying them all. I have been working through the dichotomous keys, various ID sites, and old fossil forum threads trying to get a feel for general teeth shapes. Below are three teeth that I am having trouble with. They are in fairly poor condition (especially their roots), but I think you all may be able to identified them by general shape. The first one is particularly interesting to me because it is very thick, it feels fat, bulging even on the labial side. These three teeth were collected in Georgia salt marshes (Pleistocene I believe). 

 

Thank you!

I think all three are Carcharhinus. Even if they were in perfect condition it would be difficult to identify to species because there are many Carcharhinus species and many look similar to one another.

Totally agree with Eric.

 

Check out some of the dentitions of the extant Carcharhinus species at the link below.  There are at least 32 named extant species.

I also completely agree with Al Dente on your teeth. 90% of the Carcharhinus teeth on my collection are labeled as C. sp.

Thank you all for taking the time to help a novice like me. I am quickly coming to the same understanding with my teeth that the genus level is good enough.
