This specimen is an Angustiden shark tooth, an early ancestor of the carcharodon megalodon shark. If a shark loses a tooth while biting into something, another tooth from the second row would replace the missing tooth within four minutes. Thus many teeth were lost over the lifetime of a shark. This ancient shark lived between 15 million and 25 million years ago. The ancient sharks could grow up to 50 feet in length. The carcharodon megalodon had many rows of sharp teeth. The carcharodon teeth have a single point, often with serrated edges. These teeth vary in size from small to large. The end of the tooth or root is often preserved The fossil shark teeth are often found in phosphate mines, and sometimes in beach areas. Some teeth are found by divers. A fossil shark tooth is easy to tell from a modern day shark tooth as a fossil tooth is made of stone and the modern tooth is not. Each fossil shark tooth is genuine and no two are exactly alike. The item you receive may have slight variations from the one photographed.
