Genuine Megalodon Shark Tooth (138.1 grams)
Megalodon was an prehistoric shark that may have been 40 feet (12m) long or more. (There are a few scientists who estimate it could have been up to 50 to 100 feet long -15.5 to 31m long) This is at least two or three times as long as the Great White Shark.
Their size is only a projected estimate based on the fossilized teeth and a few fossilized vertebrae that have been found.
Megalodon lived from roughly 25 to 1.6 million years ago, during the Miocene and Pliocene epochs.
