This is my Mako fossil sharktooth I found yesterday scuba diving in the Gulf of Mexico, Florida. I measured it at 2 inches. The Extinct Mako shark lived in the Miocene era approximately 12 million years ago. Mako sharks grew up to 30 feet long and had a deadly arsenal of 147 razor sharp teeth. There have been teeth found that exceed 3 Inches ! ... Therefore a 3 Inch tooth would belong to a 26 foot long Mako Shark.
