Did you know that shark teeth are quite valuable for those who collect them? Do you want to know how and why it is so? To understand this, you first need to know an interesting fact about sharks. Shark fish have been surviving for millions of years, and when they die, sand sediment provides them a covering. A shark’s teeth fall off when it dies, because its body only has cartilage that dissolves on its death. Thus, its teeth go down to the bottom of an ocean where they are fossilized over thousands of years due to possessing a cover of sand sediment.
