Rigor mortis is possibly one of the most well known of the taphonomic changes and is the process that causes the muscles in the body to stiffen resulting in rigidity due to a range of chemical changes in the muscle structure. Muscle fibers, which in life move because of sliding filament theory, rely on the conversion of ATP to ADP.

This rigidity may begin shortly after death — within 10 – 15 minutes — or may not begin until several hours later, depending on the condition of the body at the time of death and on environmental factors, such as moisture content of the air and particularly.

8. The rigor mortis will now have completed and at this peak stage the body will remain completely stiff for approximately 12 additional hours. It’s almost impossible to try to move or manipulate any particular body part without having to apply quite a bit of force.
