Here's another piece I collected a number of years ago from a Charlotte Co. FL beach. Much of it is broken, but what isn't looks like it could be part of a large tooth. The first three photos focus on the unbroken areas, two on the outside and one on what I think would have been on the inside. It's kind of difficult to grasp the shape without seeing it in person. The graph paper is 1/4 inch squares. This may be a bit of a challenge, but from what I've seen in the past, this group is up to the task. Thank you for any information.
