ID Help - North Myrtle Beach Finds (tooth, bone/turtle)

[bkstyl]

Hello, I hope all is well.  I'm looking for some help with ID'ing two items I found on North Myrtle Beach (between 13th and 15th avenue's).  The city is in the process of building a new drainage system around 18th avenue that extends out into the ocean (kind of looks like a pier). So there a a fair amount of offshore digging going on.  

 

I looked around on the web, a few other resources and a book and couldn't come to a conclusion on the ID for these items.  One is a sharks tooth (#1 is the front with ruler for size, #2 is the back, #3 is the front a little closer)...I'm thinking maybe Dusky. 

 

The other is a bone or possibly turtle (#4 side view, #5 is the back, #6 is the front, and #7 is with a ruler for size).

 

Any help you can provide would be greatly appreciated

I'd lean Bull over dusky on the tooth, and turtle on the second piece.
