Maceration (bone)
Maceration is a bone preparation technique whereby a clean skeleton is obtained from a vertebrate carcass by leaving it to decompose inside a closed container at near-constant temperature. This may be done as part of a forensic investigation, as a recovered body is too badly decomposed for a meaningful autopsy, but with enough flesh or skin remaining as to obscure macroscopically visible evidence, such as cut-marks. In most cases, maceration is done on the carcass of an animal for educational purposes.
==Description==
Maceration is a form of controlled putrefaction, a stage of decomposition in which the proteins of the body's cells are broken down and consumed by bacteria in anaerobic conditions. The temperature is usually maintained at a constant optimal temperature in an incubator. Maceration generates very strong and distasteful odors, and is therefore usually done in a closed container in a ventilated area.
Maceration is an alternative to the ''Dermestes'' method in which skin beetles are used to clean the flesh off of the corpse, a method which is used with corpses of small mammals, birds, reptiles, and amphibians, because these animals' bones tend to fall apart in many tiny parts. Maceration is an unsuitable method to clean the bones of a fish, as they have a poorly articulated, pliable skeleton.
