There is something interesting about the way these predators move and their many rows to teeth that just enthrall us. If you've been into the store with your kids, you know there is nothing cooler than to let them feel the size of a real Megalodon tooth. This tooth is from an extinct species of shark that lived over 28 to 1.5 million years ago. Carcharodon Megalodon is regarded as one of the largest predators in history and dominated the warm water seas during the Neogene Period. The only remains of these giants are their teeth and a few vertebrae. Scientists believe the C. Megalodon shark reached a length over 60 feet long and weighed over 52 tons. C. Megalodon's appearance would be similar yet six times bigger than a stocky Great White Shark. Most likely, this predator fed on large marine vertebrates, including whales.
