OK, these shouldnt be too hard. I have hunches, but not really strong on these types. 

 

First is from Belgrade mine, NC. Thinking alopias...

While your not supposed to use coins for size reference I do enjoy the 1940 wheat penny (collected coins until I realized they weren't old enough and started collecting fossils)

Looks like all are Alopias. 

 

OK. Wasnt sure on the middle three. They are so narrow compared to the others it threw me off.

I agree with Alopias sp.

 

Anterior Alopias teeth are narrow compared to the lateral and posterior teeth. Another thing to keep an eye out for is that Alopias superciliosus teeth also display marked sexual differences, especially in the anterior teeth. This sexual heterodonty produces more narrow and sinuous teeth with higher, more flexed cusps in males compared to the broader teeth in females. This isn't saying your teeth are necessarily A. superciliosus, I'm just making a general Alopias statement.

 

There's a nice comparison on Elasmo that directly discusses this in teeth of Lee Creek A. cf superciliosus with pictures. LINK
