Greetings - I have had fun with family walking the beach at Casey Key near Venice Beach, Florida. I have been enjoying the conversations here and am hoping you all may have ideas about these finds. I am posting a few overview photos - labelled - and then a few close-ups - I have more photos (larger, too). Most of these are under 6 cm (1.c which looks like a hollowed-out bone is 19 cm.). I believe 1.a ia shark's tooth and 4.c is a stingray plate. Thank you for any assistance... will look forward to your ideas - of them all the one labelled "H" (looks like some sort of claw) and item 3 "some sort of tooth" may be the most interesting? I have three others I would like to post. Noelle
