Totenkopf

Totenkopf (i.e. skull, literally dead's head) is the German word for the skull and crossbones and death's head symbols. The Totenkopf symbol is an old international symbol for death, the defiance of death, danger, or the dead, as well as piracy. It consists usually of the human skull with or without the mandible and often includes two crossed long-bones (femurs), most often depicted with the crossbones being behind some part of the skull.
