Question: How long have sharks lived? Answer : Sharks have been around for a long, long time, even before the dinosaurs! Our Sharks category has a great site called Zoom Sharks that features a cool timeline of the evolution of sharks. These toothy predators have been swimming in the ocean for over 350 million years! They even evolved over 100 million years before the dinosaurs did. Dinosaurs are long gone, but the sharks are still around. An extinct shark called the Megalodon was over forty feet long--we know about them from their fossilized teeth, which are three times as big as Great White teeth! That would give them quite a smile, don't you think?
