Hi Everyone- I'm a newbie to the forum, but a long time shark tooth hunter and general enthusiast of all things rocks, gems, fossils, and geology. Thanks so much for taking the time to help me out! I've been collecting sharks teeth for a few months from Juno Beach, Florida (~25 miles north of West Palm Beach). Usually on the surface of the sand, or, occasionally, sifting through the shell beds right at the breakers, max waist deep. I have found quite a few of these items in the first two rows, and I cannot source them online with google searches of any type. I've only tried image searching a bit, but the results were pretty crazy. What are these things? As you can see, we have left and right versions here, and some are more complete with some interesting finer features still attached. They are rock hard and feel like solid stone, cool to the touch. Most all of them are the amber/orange/brown colors, but some are darker green/brown. I would love to learn more about these! Additionally, I've put four items in the third row that are clearly different to the many items of interest, but also represent the same feel of material in a different shape. Any ideas? Here are five pics below: (this is all shot on millimeter paper, and I noted a 1 inch line, a 1 cm line, and a 1mm^2 square. 1 - top down image row 1 most complete samples of main interest row 2 - less complete samples of main interest row 3 - the second inquiry of various sizes 2 - top down image, but tilted from bottom 3 - top down image, but tilted from top 4 - top down image, all specimens turned over on opposite side relative to first three images 5 - top down image, all specimens turned over on opposite side relative to first three images, but tilted from bottom

Even tho we've lived in Florida for over 15 years, this weekend was the first time we actually went looking for shark teeth. And then again today. I confess, once I started flipping these over and looking closely, I've answered most of my own questions. Especially in light instead of quickly fading dusk! The first pic are the 2 I'm certain are real now. In particular the grey one. Next 4 are one I'm not sure about. But if I'm wrong about any others being rocks or shells please let me know! Thanks!
