Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. Knowing the different stages of decomposition can help investigators in determining the post-mortem interval (PMI). The rate of decomposition of human remains can vary due to environmental factors and other factors. Environmental factors include temperature, burning, humidity, and the availability of oxygen. Other factors include body size, clothing, and the cause of death.

👉 Corpse decomposition in the context of Mummification
A mummy is a dead human or an animal whose soft tissues and organs have been preserved by either intentional or accidental exposure to chemicals, extreme cold, very low humidity, or lack of air, so that the recovered body does not decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least the early 17th century.
Mummies of humans and animals have been found on every continent, both as a result of natural preservation through unusual conditions, and as cultural artifacts. Over one million animal mummies have been found in Egypt, many of which are cats. Many of the Egyptian animal mummies are sacred ibis, and radiocarbon dating suggests the Egyptian ibis mummies that have been analyzed were from a time frame that falls between approximately 450 and 250 BC.

Corpse decomposition in the context of Sarcophagus
A sarcophagus (pl.: sarcophagi or sarcophaguses) is a coffin, most commonly carved in stone, and usually displayed above ground, though it may also be buried. The word sarcophagus comes from the Greek σάρξ sarx meaning "flesh", and φαγεῖν phagein meaning "to eat"; hence sarcophagus means "flesh-eating", from the phrase lithos sarkophagos (λίθος σαρκοφάγος), "flesh-eating stone". The word also came to refer to a particular kind of limestone that was thought to rapidly facilitate the decomposition of the flesh of corpses contained within it due to the chemical properties of the limestone itself.
Corpse decomposition in the context of Vampire
A vampire is a mythical creature that subsists by feeding on the vital essence (generally in the form of blood) of the living. In European folklore, vampires are undead humanoid creatures that often visited loved ones and caused mischief or deaths in the neighbourhoods which they inhabited while they were alive. They wore shrouds and were often described as bloated and of ruddy or dark countenance, markedly different from today's gaunt, pale vampire which dates from the early 19th century.
Vampiric entities have been recorded in cultures around the world, but the term vampire was first popularized in Western Europe following reports of an 18th-century mass hysteria drawing on a pre-existing folk belief in Southeastern and Eastern Europe. This delusion led, in certain cases, not only to individuals being accused of vampirism, but also to the corpses of such suspected vampires being pierced with stakes.Local variants in Southeastern Europe were also known by different names, such as shtriga in Albania, vrykolakas in Greece and strigoi in Romania, cognate with Italian strega, meaning 'witch'.
Corpse decomposition in the context of Body farm
A body farm is a research facility where decomposition of humans and animals can be studied in a variety of settings. The initial facility was conceived by anthropologist William M. Bass in 1981 at the University of Tennessee in Knoxville, Tennessee, where Bass was interested in studying the decomposition of a human corpse from the time of death to the time of decay. The aim was to gain a better understanding of the decomposition process, permitting the development of techniques for extracting information such as the timing and circumstances of death from human remains. Body farm research is of particular interest in forensic anthropology and related disciplines, and has applications in the fields of law enforcement and forensic science. Numerous purposes exist for these research facilities, yet their main purpose is to study and form an understanding of the decompositional changes that occur with the human body. By placing the bodies outside to face the elements, researchers are able to get a better understanding of the decomposition process. This research is then used for medical, legal and educational purposes. Following the outdoor research, skeletal remains are cleaned and curated in permanent known skeletal collections open for research. Such collections are critical for testing and developing new identification methods.
