An out-of-place artifact (OOPArt or oopart) is an
artifact of historical, archaeological, or paleontological interest to someone that is claimed to have been found in an unusual context, which someone claims to challenge conventional
historical
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categ ...
chronology by its presence in that context. Some people might think that those artifacts are too advanced for the technology known to have existed at the time, or that
human presence existed at a time before humans are
known to have existed. Other people might hypothesize about a contact between different cultures that is hard to account for with conventional historical understanding.

es or to have conventional explanations.
Critics argue that most purported OOPArts which are not hoaxes are the result of mistaken interpretation and wishful thinking, such as a mistaken belief that a particular culture could not have created an artifact or technology due to a lack of knowledge or materials. In some cases, the uncertainty results from inaccurate descriptions. For example, the cuboid
Wolfsegg Iron is not a perfect cube, nor are the
Klerksdorp spheres perfect spheres. The
Iron pillar of Delhi was said to be "rust proof", but it has some rust near its base; its relative resistance to corrosion is due to slag inclusions left over from the manufacturing conditions and environmental factors.
Supporters regard OOPArts as evidence that mainstream science is overlooking huge areas of knowledge, either willfully or through ignorance.
Many writers or researchers who question conventional views of human history have used purported OOPArts in attempts to bolster their arguments.
