I grew up going to the SC coast with my mom(actually lived there the first few years of my life). I've never lost my fascination with searching for shark teeth(my profile photo is my mother, my deceased sister, and myself at a very young age, looking at our former home in Garden City, SC), and it's known within the group of friends that my wife and I vacation with. Point is, I found this last year at Carolina Beach in NC. I pride myself on a keen eye, but I initially thought it to be nothing more than an ironically accurate shaped piece of wood. I kept it none the less, and "white-lied" to the other couples with us in our airbnb that i was confident it was a tooth. I forgot all about it until about a week ago. After a little research, I'm pretty sure it is, in fact, a tooth. But, I'm leaning towards a reptile. Again, I'm an amateur, just hoping someone can give me an answer. Thanks in advance.
