    I’m unsure what you’ve got there. Croc toe wouldn’t be my first guess, but I really don’t know. @joyce-drakeford

    Ginglymostoma is the genus of nurse shark most often found at Belgrade.  I have seen an excellent image of an actual Nebrius tooth from there but it was from the Eocene rather than the Oligocene/Miocene formations.  To differentiate the two genus, the center cusp on Ginglymostoma is noticeably much larger than the lateral cusps and stands out as in your tooth.  In Nebrius, the center cusp is larger but not as exaggerated as in Ginglymostoma.  I suspect that by the late Oligocene, Nebrius no longer existed in the Atlantic.

    Thank you for the information on the nurse shark teeth at the Belgrade Quarry.  I would like to label the nurse shark teeth that I have collected at the quarry, do you think all of these are Ginglymostoma?

    Hi, @julie-niederkorn!  Perhaps @bill-heim, @vperez, or @rleder could help you with your labels.  I don’t think they received a notification about your post.

    Julie @julie-niederkorn, that is a Hemipristis lower anterior tooth.    Here is an image of a large one from Florida.

    Larger images of the nurse shark teeth would help.   The center 2 teeth are clearly Ginglymostoma as is the second from the right.  Some of the others, I am not so sure.
