When this occurs bodily tissues can be preserved, but it as extremely rare occurrence. When an organic item is buried in sediment, heat and pressure causes the release of hydrogen and oxygen, which leaves behind a carbon residue.

Dating technqies can be split into two groups: When dating sediments the source of the organic matter and the likelihood of any age discrpancy between the material and the sediments in which they are found need to be considered.

For example, sediments can contein organic materials eroded and redeposited from older sediments, in this case the organic matter will be considerably older than the sediments with which it is associated.

Instead it is usually worked into the soil by a series biological, physical and / or chemical processes.

This means that a soil sample will contain a mixture of particles each potentially dating to any period within the history of the soils development; hence, The dynamics or organic matter and mineral grain inclusion in the soil is an important factor in the measured date.

It is hoped that absolute dating will be successfully implemented in the future in this region.

Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.

The term refers to the fact that an approximate date can be inferred by comparison with something else of known age.

Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.

One thing to keep in mind is that, "the fossil record is highly skewed in favor of organisms that died and were preserved in calm seas, estuaries, tidal flats, or the deep ocean floor (where there are few scavengers and little disruption of layers)" (Panell 2014: 1839). Permineralization, or petrification, is the most common process.

This occurs when organic remains decay and water seeps into the remains and deposits minerals that form crystals which harden.
