A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
Otherwise, however, younger people generally putrefy more quickly than older people. [citation needed] Condition of the body: A body with a greater fat percentage and less lean body mass will have a faster rate of putrefaction, as fat retains more heat and it carries a larger amount of fluid in the tissues.

The cause of postmortem caloricity varies depending on the cause of death: Postmortem glycogenolysis – a phenomenon beginning soon after death observed in nearly all cadavers. In an average adult, postmortem glycogenolysis can produce up to 140 calories of heat which can raise the temperature of the body by up to 2 °C.
Up to 13 hours after death, eyeball cooling in pigs provides a reasonable estimate of time since death. [30] After 13 hours, muscle and rectal temperatures in pigs are better estimates of time since death. [31] In dogs: what changes and when. Eye K+ decreases from 1.5 hours after death to 7 hours after death. [32]
A large flock of vultures can reduce human corpse or carcass of large animal to skeleton within few hours. After skeletonization, if scavenging animals do not destroy or remove the bones, acids in many fertile soils take about 20 years to completely dissolve the skeleton of mid- to large-size mammals, such as humans, leaving no trace of the ...
A company called Tomorrow Biostasis is focusing on human cryopreservation in the hopes it can eventually reverse death.. The new Berlin startup has already preserved the bodies of about 10 ...
A measured rectal temperature can give some indication of the time of death. Although the heat conduction which leads to body cooling follows an exponential decay curve, it can be approximated as a linear process: 2 °C during the first hour and 1 °C per hour until the body nears ambient temperature.
Since 2003, 954 confirmed cases of human H5N1 have been reported to the World Health Organization, and about half of those people have died. The case fatality rate is approximately 52%, per the CDC .
