Hepatocytes individualize over 6 hours after death. [35] In canine livers, the bile duct epithelium detaches from the basement membrane after 3 days. Hepatocyte nuclei autolyze by 7 days. [36] In equine livers, autolysis can occur as early as 1 hour after death. Autolysis progresses over 72 hours. [37]
After death, when a body is submerged in water a process called Saponification occurs. This is the process in which adipocere is formed. This is the process in which adipocere is formed. Adipocere is a wax-like substance that covers bodies created by the hydrolysis of triglycerides in adipose tissue.
Decomposition in animals is a process that begins immediately after death and involves the destruction of soft tissue, leaving behind skeletonized remains. The chemical process of decomposition is complex and involves the breakdown of soft tissue, as the body passes through the sequential stages of decomposition. [2]
The approximate time it takes putrefaction to occur is dependent on various factors. Internal factors that affect the rate of putrefaction include the age at which death has occurred, the overall structure and condition of the body, the cause of death, and external injuries arising before or after death.
A body buried in a sufficiently dry environment may be well preserved for decades. This was observed in the case for murdered civil rights activist Medgar Evers, who was found to be almost perfectly preserved over 30 years after his death, permitting an accurate autopsy when the case of his murder was re-opened in the 1990s.

Livor mortis (from Latin līvor 'bluish color, bruise' and mortis 'of death'), postmortem lividity (from Latin post mortem 'after death' and lividitas 'black and blueness'), hypostasis (from Greek ὑπό (hypo) 'under, beneath' and στάσις (stasis) 'a standing') [1] [2] or suggillation, is the second stage of death and one of the signs of ...
Autolysis is uncommon in living adult organisms and usually occurs in necrotic tissue as enzymes act on components of the cell that would not normally serve as substrates. These enzymes are released due to the cessation of active processes in the cell that provide substrates in healthy, living tissue; autolysis in itself is not an active process.
Skeletonization is the state of a dead organism after undergoing decomposition. [1] Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed. By the end of the skeletonization process, all soft tissue will ...
