Black putrefaction

Body in stages of black putrefaction. Black putrefaction is the stage where the exposed flesh blackens, and the internal organs and tissues take on a creamy consistency. The body then hastens toward fermentation and molding, referred to as butyric fermentation. This stage typically occurs after rigor mortis has passed, and the body begins to emit a foul odor. Black putrefaction is a key factor in estimating time since death in forensic investigations and can provide important information about the cause of death and circumstances surrounding it.
