With 75% of the Earths surface covered with water it's no surprise that there is such a huge diversity of creatures that live - and have lived in the seas and oceans.
Sharks are such an effective killing machine that you would expect them to have flourished for a long period of time - and you would be right!
On this page I offer a good selection of teeth from a wide variety of sharks. Some are still swimming today - and some, like the incredible Megalodon have died out.
Have a browse through these teeth and we're sure you will find something to improve your fossil collection or that would make a super gift. Children especially love sharks, and I sell many teeth to young shark fiends!
