Unsolved:Out-of-place artifact

From HandWiki
Short description: Objects that challenge historical chronology
Fragment of the Antikythera mechanism, a mechanical computer from the 2nd century BCE showing a previously unknown level of complexity

An out-of-place artifact (OOPArt or oopart) is an artifact of historical, archaeological, or paleontological interest found in an unusual context, which challenges conventional historical chronology by its presence in that context. Such artifacts may appear too advanced for the technology known to have existed at the time, or may suggest human presence at a time before humans are known to have existed. Other examples may suggest contact between different cultures that is hard to account for with conventional historical understanding.

This description of archaeological objects is used in fringe science such as cryptozoology, as well as by proponents of ancient astronaut theories, young Earth creationists, and paranormal enthusiasts.[1][2] It can describe a wide variety of items, from anomalies studied by mainstream science to pseudoarchaeology to objects that have been shown to be hoaxes 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 really a perfect cube, nor are the Klerksdorp spheres actual 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.[3]

Supporters regard OOPArts as evidence that mainstream science is overlooking huge areas of knowledge, either willfully or through ignorance.[2] Many writers or researchers who question conventional views of human history have used purported OOPArts in attempts to bolster their arguments.[2] Creation science often relies on allegedly anomalous finds in the archaeological record to challenge scientific chronologies and models of human evolution.[4] Claimed OOPArts have been used to support religious descriptions of prehistory, ancient astronaut theories, and the notion of vanished civilizations that possessed knowledge or technology more advanced than that known in modern times.[2]

Unusual artifacts

  • Antikythera mechanism: A form of mechanical computer created between 150 and 100 BCE based on theories of astronomy and mathematics believed to have been developed by the ancient Greeks. Its design and workmanship reflect a previously unknown, but not implausible, degree of sophistication and engineering.[5][6]
  • Maine penny: An 11th-century Norway coin found in a Native American shell midden at the Goddard Site in Brooklin, Maine, United States , which some authors have argued is evidence of direct contact between Vikings and Native Americans in Maine. The coin need not imply actual exploration of Maine by the Vikings, however; mainstream belief is that it was brought to Maine from Labrador or Newfoundland (where Vikings are known to have established colonies as early as the late 10th century) via an extensive northern trade network operated by indigenous peoples.[7] If Vikings did indeed visit Maine, a much greater number and variety of Viking artifacts might be expected in the archaeological record there.[citation needed] Of the nearly 20,000 objects found over a 15-year period at the Goddard Site, the coin was the sole non-native artifact.[8]
The Shroud of Turin: modern photo of the face, positive left, digitally processed negative image right
  • The Shroud of Turin, an ancient cloth which contains an image that resembles a sepia photographic negative. The image is much clearer when it is converted to a positive image, which was discovered by photographer Secondo Pia in 1898. The actual method that resulted in this image has not yet been conclusively identified. Some claim the image depicts Jesus of Nazareth and the fabric is the burial shroud in which he was wrapped after crucifixion. Mention of the shroud first appeared in historical records in 1357. In 1988, radiocarbon dating established that the shroud was from the Middle Ages, between the years 1260 and 1390.[9] All hypotheses put forward to challenge the radiocarbon dating have been scientifically refuted,[10] including the medieval repair hypothesis,[11][12][13] the bio-contamination hypothesis[14] and the carbon monoxide hypothesis.[15]
The Tamil Bell is a broken bronze bell used as a cooking pot by Māori women of New Zealand.
  • The Tamil Bell is a broken bronze bell with an inscription of old Tamil. The bell is a mystery due to its discovery in New Zealand by a missionary. Although nobody knows for certain how the bell came to New Zealand, one possible theory is that it was dropped off by Portuguese sailors who had acquired it from Tamil traders. Prior to being discovered by the missionary, local Maori had used it as a cooking pot. Given that it was supposedly discovered generations earlier, the artifact's exact origins could not be identified. The bell is now located at the National Museum of New Zealand.[16]
  • Coins from Marchinbar Island: Five coins from the Kilwa Sultanate on the Swahili coast discovered on Marchinbar Island in the Northern Territory of Australia in 1945 alongside four coins from 18th century Netherlands. The inscriptions on the coins identify a ruling Sultan of Kilwa, but it is unclear whether the ruler was from the 10th century or the 14th century. A similar coin, also thought to be from the Medieval Kilwa sultanate, was found in Australia in 2018 on Elcho Island.[17]

Questionable interpretations

The three components of the Baghdad Battery
  • Baghdad Battery: A ceramic vase, a copper tube, and an iron rod made in Parthian or Sassanid Persia, discovered in 1936. Fringe theorists have hypothesized that it may have been used as a galvanic cell for electroplating, though no electroplated artifacts from this era have been found.[18][19] The "battery" strongly resembles another type of object with a known purpose – storage vessels for sacred scrolls from nearby Seleucia on the Tigris.[20]
  • Dorchester Pot: A metal pot claimed to have been blasted out of solid rock in 1852. Mainstream commentators identify it as a Victorian-era candlestick or pipe holder.[21][22]
  • Kingoodie artifact: An object resembling a corroded nail, said to have been encased in solid rock. It was handled a number of times before being reported and there are no photographs of it.[23][24]
  • Lake Winnipesaukee mystery stone: Originally thought to be a record of a treaty between tribes, subsequent analysis has called its authenticity into question.[25][26]
  • Sivatherium of Kish: An ornamental war chariot figurine discovered in the Sumerian ruins of Kish, in what is now central Iraq, in 1928. The figurine, dated to the Early Dynastic I period (2800–2750 BCE), depicts a quadrupedal mammal with branched horns, a nose ring, and a rope tied to the ring. Because of the shape of the horns, Edwin Colbert identified it in 1936 as a depiction of a late-surviving, possibly domesticated Sivatherium, a vaguely moose-like relative of the giraffe that lived in North Africa and India during the Pleistocene but was believed to have become extinct early in the Holocene extinction event.[27] Henry Field and Berthold Laufer instead argued that it represented a captive Persian fallow deer and that the antlers had broken over the years. The missing antlers were indeed found in the Field Museum's storeroom in 1977.[28] After restoration in 1985, it was conclusively identified as a depiction of a Caspian red deer (Cervus elaphus maral).[29]
  • Tecaxic-Calixtlahuaca head: A terracotta offering head seemingly of Roman appearance found beneath three intact floors of a burial site in Mexico and dated between 1476 and 1510. There are disputed claims that its dating is older. Ancient Roman or Norse provenance has not been excluded.[30][31]

Alternative interpretations

The iron pillar of Delhi
  • Abydos helicopter: A pareidolia based on palimpsest carving in an ancient Egyptian temple.[32]
  • Dendera Lamps: Supposed to depict light bulbs, but made in Ptolemaic Egypt, debunked by the analysis of the epigraphic text.[33][34][35]
  • Sabu disk: a disk of notable precision apparently from ancient times in Saqqara. Its purpose is unknown.[36]
  • Iron Man (Eiserner Mann): An old iron pillar, said to be a unique oddity in Germany , but consistent with medieval methods of ironworking.[37]
  • Iron pillar of Delhi: A "rust-proof" iron pillar which supposedly demonstrates more advanced metallurgy than was available in India before 1000 CE.[38]
  • London Hammer: Also known as the "London Artifact", a hammer made of iron and wood that was found in London, Texas, in 1936. Part of the hammer is encased in "400-million-year-old" ("Ordovician era") rock. In 1985, anthropologist John R. Cole[39] hypothesized that the stone surrounding the hammer is a historic carbonate soil concretion.
  • Meister Print: A supposed human footprint from the Cambrian period, long before humans existed, which has been debunked as the result of a natural geologic process known as spall formation.[40]
  • Pacal's sarcophagus lid: Described by Erich von Däniken as a depiction of a spaceship.[41]
  • Piri Reis map: Several authors, and others such as Gavin Menzies and Charles Hapgood, have suggested that this map, compiled by the Turkish admiral Piri Reis, shows Antarctica long before it was discovered (cf. Terra Australis).[42][43]
  • Quimbaya airplanes: Golden objects found in Colombia and made by the Quimbaya civilization, which have been alleged to represent modern airplanes. In the Gold Museum, Bogotá, they are described as figures of birds and insects. Some of the artifacts have also been debunked as forgeries.[44]
  • Saqqara Bird: Supposedly depicts a glider, but made in Ancient Egypt.[45]
  • Shakōkidogū: Small humanoid and animal figurines made during the late Jōmon period (14,000–400 BCE) of prehistoric Japan, said to resemble extraterrestrial astronauts.[46]
  • Stone spheres of Costa Rica: Inaccurately described as being perfectly spherical, and therefore demonstrating greater stone-working skill in pre-Columbian times than has previously been known.[47]

Natural objects mistaken for artifacts

Eltanin Antenna
  • Aix-en-Provence petrified tools: Likely petrified tree remains.[48][49]
  • Baigong pipes: Their natural origins have been challenged.[50][51][52]
  • Bosnian pyramid complex: Unproven claim that there is a pyramid complex in the vicinity of town of Visoko in Bosnia.
  • Eltanin Antenna: Actually a sponge.[53][54]
  • Eoliths: Miocene knapped flint nodules mistaken in the 19th century for extremely primitive stone tools, which helped back the authenticity of Piltdown man.
  • Face on Mars: A pareidolia of a rock formation on Mars caused by the poor resolution of early orbital photography of the planet.[55]
  • Klerksdorp spheres: Actually pre-Cambrian concretions.[56][57]
  • Paluxy River tracks: Identified as giant humanoid footprints found alongside dinosaur tracks. Actually tracks of theropod dinosaurs, and 1930s forgeries.
  • Yonaguni Monument: An unusual underwater rock formation near the southern Ryukyu Islands, was considered a man-made monolith because of the even cracks.[58][59]
  • Ararat anomaly: The Ararat anomaly is a structure appearing on photographs of the snowfields near the summit of Mount Ararat, Turkey, initially believed by some Christian believers to be the remains of Noah's Ark. Located on the northwest corner of the Western Plateau of Mount Ararat, approximately 15,500 ft high, it was first filmed during a U.S. Air Force aerial reconnaissance mission in 1949. The Defense Intelligence Agency later indicated that the anomaly represents linear facades in the glacial ice, rather than an ancient structure.[60][61]

Erroneously dated objects

  • Aiud object: An aluminum wedge found in 1974 in the Mureș River in central Romania, near the town of Aiud; it has been claimed by Romanian UFOlogists to be of ancient and/or extraterrestrial origin,[62] yet it is more likely a fragment of modern machinery lost during excavation work.[63]
  • Coso artifact: Claimed to be prehistoric; actually a 1920s spark plug.[4]
  • Malachite Man: Thought to be from the early Cretaceous; actually a post-Columbian burial.[64][65]
  • Nampa figurine: Was a clay fired doll found in Nampa, Idaho during a well drilling. Early dating attempts believed the artifact to be 2 million years old due to the rock layer it was found in.[66] Later assessments found that the artifact was either only a few thousand years old[67] or a 19th-century Native American doll. Many have criticized the object as a likely hoax.[68]
  • Wolfsegg Iron: Thought to be from the Tertiary epoch; actually from an early mining operation. Inaccurately described as a perfect cube.[69]

Modern-day creations, forgeries and hoaxes

Babylonokia
  • Babylonokia: A clay tablet shaped like a mobile phone and created as an artwork in 2012. Fringe scientists and alternative archaeology proponents subsequently misrepresented a photograph of the artwork as showing an 800-year-old archaeological find. The story was popularised in a video on the YouTube channel Paranormal Crucible and led to the object being reported by some press sources as a mystery.[70]
  • Acámbaro figures: Mid-20th-century figurines of dinosaurs, attributed by Waldemar Julsrud to an ancient society.[71]
  • Calaveras Skull: A human skull found by miners in Calaveras County, California, which was purported to prove that humans, mastodons, and elephants had coexisted in prehistoric California. It was later revealed to be a hoax.[72]
  • Cardiff Giant: A 19th-century hoax of a ten-foot-tall supposedly petrified man exhibited as a giant from biblical times. Quickly debunked by experts, and by the confession of the forger,[73] it was nonetheless a popular marvel of the day.[74]
  • Crystal skulls: Supposedly demonstrate more advanced stone-cutting skill than was previously known from pre-Columbian Mesoamerica. Appear to have been made in the 19th century.[75]
  • Gosford Glyphs: A collection of Egyptian hieroglyphs in Central Coast, Australia, that have been dismissed as a hoax by authorities and academics after their discovery in the 1970s.[76]
  • Ica stones: Depict Inca dinosaur-hunters, surgery, and other modern or fanciful topics. Collected by Javier Cabrera Darquea, who claimed them to be prehistoric. Later revealed to be a forgery created by a local farmer.[77]
  • Japanese Paleolithic hoax: Perpetrated by discredited amateur archaeologist Shinichi Fujimura.[78]
  • Kensington Runestone: A runestone purportedly unearthed in 1898 in Kensington, Minnesota entangled in the roots of a tree. Runologists have dismissed the inscription's authenticity on linguistic evidence, while geologists disagree as to whether the stone shows weathering that would indicate a medieval date.[79]
  • Los Lunas Decalogue Stone: Supposedly made by pre-Columbian Israelite visitors to the Americas. Generally believed to be a modern-day hoax.[80]
  • Michigan relics: Supposedly ancient artifacts which have been alleged as proof that people of an ancient Near Eastern culture had lived in the U.S. state of Michigan; they are archaeological forgeries.[81]
  • Newark Holy Stones: Hoax "artifacts" used as extremely unlikely evidence that Hebrew peoples lived in the Precolumbian Americas.[82]
  • Piltdown Man: Supposedly skull parts from a "missing link" hominid, but exposed as an elaborate hoax 41 years after its "discovery".[83]
  • Tucson artifacts: Thirty-one lead objects that Charles E. Manier and his family found in 1924 near Picture Rocks, Arizona, which were initially thought by some to be created by early Mediterranean civilizations that had crossed the Atlantic in the first century, but were later determined to be a hoax.[84]
