These shark teeth are from the Gulf Of Mexico Venice Florida and are millions of years old, Piacenzian / Pliocene era on the Geologic time table. They range in size from 1/8 - 3/4 inch and are from many species of sharks such as Bull, Hammerhead, Sand Tiger, and many other species. * PLEASE NOTE * These are partial teeth ( pieces ) and are not for wire wrapping. These teeth are great for craft projects and other uses. Please be sure to visit my eBay store for more great deals on shark teeth including whole teeth up to 1 inch, jewelry, fossilized shells, and thousands of other items. Thanks for looking and have a great day, Jeff B.
