What is "xenoarchaeology"

n. (context science fiction English) A fictional science, concerned with the physical remains of alien cultures. These may be found on planets which have been inhabited or visited by extraterrestrials.

Xenoarchaeology is a hypothetical form of archaeology that exists mainly in works of science fiction. The field is concerned with the study of material remains to reconstruct and interpret past life-ways of alien civilizations. Xenoarchaeology is not currently practiced by mainstream archaeologists due to the current lack of any material for the discipline to study.
