Even if elephants come across the body of another elephant that has been long dead, its remains picked apart by hyenas and its skeleton scattered, they bunch and get tense. They approach the carcass as a group, and caress the bones with what can only be described as reverence. They stroke the dead elephant, touching it all over with their trunks and their back feet. They will smell it. They might pick up a tusk or a bone and carry it for a while. They will place even the tiniest bit of ivory under their feet and gently rock back and forth.
