Deetjens bodies, also known as mummified bodies, refer to preserved human remains that have undergone natural mummification processes such as desiccation or freezing. Synonymously, these bodies can be referred to as ancient desiccated corpses, dried cadavers, or arid mummies. The term "Deetjens bodies" originated from the fascinating preservation of bodies found in the Deetjens Cliff Cave in Utah, USA, where countless well-preserved mummies were discovered. However, to describe similar preserved bodies discovered elsewhere, synonyms like desiccated remains, dried-out corpses, or even mummified cadavers can be used interchangeably. These terms acknowledge the unique state of preservation these bodies have undergone, showcasing their remarkable historical and scientific significance.
