An invisible elephant graveyard on the African prairie

An elephant is a very spiritual animal. It is said that an elephant can predict his own death. When the old elephant knows the limit is coming, it will sneak out of the elephant group and hide it alone into the elephant graveyard in the dense forest valley, where it is waiting for death. For hundreds of years, there are similar legends as long as there are elephants. Indeed, although the elephant's body is huge, no one has ever seen the bodies of wild elephants. Where have all of them gone? According to an African Kenya chief, he once lost his way in hunting and stumbled into a bone filled cave. From the size and shape of the skeleton, elephants should be left behind. He also saw an elephant staggering in and fell dead on the ground. The two former Soviet explorers went in search of directions, and saw a valley full of animal bones.

Does the elephant graveyard exist? Some people think that this is just a lie made by some poachers to cover up the crime of hunting elephants. There had been such a tragedy in 1920s: a group of elephants were heavily huned by European explorers, and they were not lucky enough to meet a forest fire. The explorers got a lot of ivory, so they made up the story of the elephant graveyard.

Some zoologists have witnessed the funeral of elephants. The elephants surrounded the dead companions for mourning, then dug out the pit with their tusks, and rolled up stones with their noses to bury them. But all those buried are female elephants or baby elephants. The bodies of the elephants with precious Ivory have never been found. Some people thought they were all in the marsh before death, so people could not find their bodies. But how do elephants know their dead time?
