Why would a toothed whale and a marsupial possum be buried together in Tasmania? Well, these creatures from vastly different habitats are part of a massive fossil graveyard of thousands of creatures all buried together.

And actually we find these graveyards all over the world. One is made up of trillions of microscopic marine creatures. It stretches through Europe into the Middle East—and even into the Midwest of the US! You would probably recognize a small part of these chalk beds as, well, the famous White Cliffs of Dover in England.

Now, what could bury creatures on such a massive scale? The global flood of Noah’s day.
