1. Prehistoric Megalodon was the largest predator that ever lived, dwarfing its modern relative, the great white shark. If you could place a fully grown Megalodon upright on its nose, it would be as tall as what? a California redwood tree the Statue of Liberty the Eiffel tower a six-story building

2. What does "Megalodon" mean? mighty galleon massive jaw giant tooth loud roar

3. Megalodon's main prey was Odobenocetops, which was what sort of creature? a whale a bizarre form of amphibious sloth a prehistoric seal a giant squid

4. Megalodon had to eat at least 2 percent of its 20 ton body weight, or half a ton, daily to maintain its existence. This is proportionately a bit less than a human being eats. Why do humans eat more than sharks? because human brains need more energy to keep their bodies warm because water buoys fish up so they need less energy than humans to move nobody knows for sure

6. Megalodon appeared in prehistoric oceans during the Oligocene Period and ruled the oceans for 20 million years. It became extinct 2 million years ago, due to what phenomenon? volcanic eruptions in the ocean floor cooling of the oceans a virus that attacked its immune system a huge meteorite

7. Only fossilised Megalodon jaws and teeth have been found ? never any Megalodon skeletons. Why not? marine archaelogists can't work at those depths 2 million years or more in sea water will erode the hardest bones megalodon had no bones the bones crumble away at the first contact with air

8. Marine "treasure hunters" are always eager to find fossilised Megalodon teeth, as there is a ready market for them. Who are the eager purchasers? orthodontic researchers the adherents of certain religious cults museums and private collectors manufacturers of alternative medicines

9. What colour are fossilised Megalodon teeth? blood red white they can be any colour at all black

10.
