“Oopart”—or “out-of-place artifact”—is the term given to numerous prehistoric objects found in various places across the world today that show a level of technological sophistication incongruous with our present paradigm.
Many scientists attempt to explain these ooparts away as natural phenomena. Yet others say that such dismissive explanations only whitewash over the mounting evidence: that prehistoric civilizations had advanced knowledge, and this knowledge was lost over the ages only to be developed anew in modern times.
We will look at a variety of ooparts here, ranging from millions to hundreds of years old in purported age, but all supposedly demonstrating advancement well beyond their time.
Whether these are fact or merely fiction we cannot say. We can only offer a glimpse at what’s known, supposed, or hypothesized regarding these phenomena, in the spirit of being open-minded and geared toward real scientific discovery.
Clay jars with asphalt stoppers and iron rods made some 2,000 years ago have been proven capable of generating more than a volt of electricity. These ancient “batteries” were found by German archaeologist Wilhelm Konig in 1938, just outside of Baghdad, Iraq.
“The batteries have always attracted interest as curios,” Dr. Paul Craddock, a metallurgy expert at the British Museum, told the BBC in 2003. “They are a one-off. As far as we know, nobody else has found anything like these. They are odd things; they are one of life’s enigmas.”
16. Ancient Egyptian Light Bulb?
A relief beneath the Temple of Hathor at Dendera, Egypt, depicts figures standing around a large light-bulb-like object. Erich Von Däniken, who wrote “Chariot of the Gods,” created a model of the bulb which works when connected to a power source, emitting an eerie, purplish light.
15. Great Wall of Texas
In 1852, in what is now known as Rockwall County, Texas, farmers digging a well discovered what appeared to be an ancient rock wall. Estimated to be some 200,000 to 400,000 years old, some say it’s a natural formation while others say it’s clearly man-made.
Geologist James Shelton and Harvard-trained architect John Lindsey have noted elements that seem to be of architectural design, including archways, linteled portals, and square openings that resemble windows.
14. 1.8-Billion-Year-Old Nuclear Reactor?
In 1972, a French factory imported uranium ore from Oklo, in Africa’s Gabon Republic. The uranium had already been extracted. They found the site of origin to have apparently functioned as a large-scale nuclear reactor that came into being 1.8 billion years ago and was in operation for some 500,000 years.
Dr. Glenn T. Seaborg, former head of the United States Atomic Energy Commission and Nobel Prize winner for his work in the synthesis of heavy elements, believed it wasn’t a natural phenomenon, and thus must be a man-made nuclear reactor.
For uranium to “burn” in a reaction, very precise conditions are needed. The water must be extremely pure, for one—much purer than exists naturally. The material U-235 is necessary for nuclear fission to occur. It is one of the isotopes found naturally in uranium. Several specialists in reactor engineering have said they believe the uranium in Oklo could not have been rich enough in U-235 for a reaction to take place naturally.
A map created by Turkish admiral and cartographer Piri Reis in 1513, but sourced from various earlier maps, is thought by some to depict Antarctica as it was in a very remote age before it was covered with ice.
A landmass is shown to jut out from the southern coastline of South America. Captain Lorenzo W. Burroughs, a U.S. Air Force captain in the cartographic section, wrote a letter to Dr. Charles Hapgood in 1961 saying that this landmass seems to accurately show Antarctica’s coast as it is under the ice.
Dr. Hapgood (1904–1982) was one of the first to publicly suggest that the Piri Reis map depicts Antarctica during a prehistoric time. He was a Harvard-educated historian whose theories about geological shifts earned the admiration of Albert Einstein. He hypothesized that the land masses shifted, explaining why Antarctica is shown as connected to South America.
Modern studies refute Hapgood’s theory that such a shift could have taken place within thousands of years, but they show it could have happened within millions of years.
12. 2,000-Year-Old Earthquake Detector
In 132 A.D., Zhang Heng created the world’s first seismoscope. How exactly it works remains a mystery, but replicas have worked with a precision comparable to modern instruments.
In 138 A.D., it correctly indicated that an earthquake occurred about 300 miles west of Luoyang, the capital city. No one had felt the quake in Luoyang and dismissed the warning until a messenger arrived days later, requesting aid.
11. 150,000-Year-Old Pipes?
Caves near Mount Baigong in China contain pipes leading to a nearby lake. They were dated by the Beijing Institute of Geology to about 150,000 years ago, according to Brian Dunning of Skeptoid.com.
State-run media Xinhua reported that the pipes were analyzed at a local smeltery and 8 percent of the material could not be identified. Zheng Jiandong, a geology research fellow from the China Earthquake Administration, told state-run newspaper People’s Daily, in 2007, that some of the pipes were found to be highly radioactive.
Jiandong said iron-rich magma may have risen from deep in the Earth, bringing the iron into fissures where it may have solidified into tubes; though he admitted, “There is indeed something mysterious about these pipes.” He cited the radioactivity as an example of the strange qualities of the pipes.
A mechanism often referred to as an ancient “computer,” which was built by Greeks around 150 B.C., was able to calculate astronomical changes with great precision.
“If it hadn’t been discovered … no one would possibly believe that it could exist because it’s so sophisticated,” said Mathematician Tony Freeth in a NOVA documentary. Mathias Buttet, director of research and development for watch-maker Hublot, said in a video released by the Hellenic Republic Ministry of Culture and Tourism, “This Antikythera Mechanism includes ingenious features which are not found in modern watch-making.”
9. Drill Bit in Coal
John Buchanan, Esq., presented a mysterious object to a meeting of the Society of Antiquaries of Scotland on Dec. 13, 1852. A drill bit had been found encapsulated in coal about 22 inches thick, buried in a bed of clay mixed with boulders about 7 feet thick.
The Earth’s coal is said to have formed hundreds of millions of years ago. The Society decided that the instrument was of a modern level of advancement. But it concluded that “the iron instrument might have been part of a borer broken during some former search for coal.”
8. 2.8-Billion-Year-Old Spheres?
Spheres with fine grooves around them, found in mines in South Africa, have been said by some to be naturally formed masses of mineral matter. Others have said they were precisely shaped by a prehistoric human hand.
“The globes, which have a fibrous structure on the inside with a shell around it, are very hard and cannot be scratched, even by steel,” said Roelf Marx, curator of the museum of Klerksdorp, South Africa, according to Michael Cremo’s book, “Forbidden Archaeology: The Hidden History of the Human Race.” Marx said the spheres are about 2.8 billion years old.
If they are mineral masses, it is unclear how exactly they formed.
7. Iron Pillar of Delhi
This pillar is at least 1,500 years old but could be older. It remains rust-free and is of astounding purity. It is 99.72 percent iron, according to professor A.P. Gupta, head of the Department of Applied Sciences and Humanities at the Institute of Technology and Management in India.
In modern times, wrought iron has been made with a purity of 99.8 percent, but it contains manganese and sulfur, two ingredients absent in the pillar.
It was made at least “400 years before the largest known foundry of the world could have produced it,” wrote John Rowlett in “A Study of the Craftsmen of Ancient and Medieval Civilizations to Show the Influence of their Training on our Present Day Method of Trade Education.”
6. Viking Sword Ulfberht
When archaeologists found the Viking sword Ulfberht, dating from 800 to 1000 A.D., they were stunned. They couldn’t see how the technology to make such a sword would have been available until the Industrial Revolution, 800 years later.
Its carbon content is three times higher than other swords of its time and impurities were removed to such a degree that the iron ore must have been heated to at least 3,000 degrees Fahrenheit.
5. 100-Million-Year-Old Hammer?
A hammer was found in London, Texas, in 1934, encased in stone that had formed around it. The rock surrounding the hammer is said to be more than 100 million years old.
Glen J. Kuban, a vocal skeptic of claims that the hammer was made millions of years ago, said the stone may contain materials that are more than 100 million years old, but that doesn’t mean the rock formed around the hammer so long ago.
He said that some limestone has formed around artifacts known to be from the 20th century, so concretions can form fairly quickly around objects. (Concretions are masses of hardened mineral matter).
Carl Baugh, who was in possession of the artifact, has said the wooden handle has turned to coal (evidence of its great age) and that the metal its made of has a strange composition. Critics have called for independent testing to verify these claims, but so far no such testing has been conducted.
4. Prehistoric Work Site?
Workers at a stone quarry near Aix-en-Provence, France, in the 18th century, came across tools stuck in a layer of limestone 50 feet underground.
The wooden instruments had turned into agate, a hard stone. Porter wrote: “Everything tended to prove that this work had been executed upon the spot where the traces existed. The presence of man had then preceded the formation of this stone, and that very considerably since he was already arrived at such a degree of civilization that the arts were known to him, and that he wrought the stone and formed columns out of it.”
As stated in the case of the hammer above, limestone has been known to form relatively quickly around modern tools.
3. Million-Year-Old Bridge?
According to ancient Indian legend, King Rama built a bridge between India and Sri Lanka more than a million years ago. What appears to be remnants of such a bridge have been seen from satellite images, but many say its a natural formation.
No single natural explanation has been agreed upon by geologists. Dating has been controversial, as some say any given part of the bridge (such as coral samples) cannot give a true picture of how old the entire bridge is.
2. 500,000-Year-Old Spark Plug?
In 1961, three people were out searching for geodes for their gem and gift shop in Olancha, California, when they found what appeared to be a spark plug encased in a geode. Virginia Maxey, one of the three discoverers, said at the time that a geologist examined the fossils around the device and dated the device at 500,000 years old or older.
The geologist was never named, and the current whereabouts of the artifact are unknown. Critics of the claim, Pierre Stromberg and Paul V. Heinrich, only have x-rays and an artist’s sketch of the artifact to analyze. They think it was a modern spark plug encased in a quick-forming concretion rather than a geode.
But, Stromberg and Heinrich have said, “There is little hard evidence that the original discoverers intended to deceive anyone.”
1. Prehistoric Wall Near Bahamas?
A wall of rock in large, thick block shapes was found off the coast of the Bahamas in 1968. Archaeologist William Donato has conducted multiple dives to investigate the wall and hypothesizes it is a man-made structure some 12,000 to 19,000 years old, built to protect a prehistoric settlement from waves.
Dr. Eugene Shinn, a retired geologist who worked for the U.S. Geological Survey, has said core rock samples he took show a dip toward deep water. If all the cores show a dip toward deep water, this would prove the rock formed where it is and did not form elsewhere, later to be transported by humans to its present location.
His later writings said that all of his samples showed this dip, seeming to prove it is a natural formation. But his earlier study stated that only 25 percent of his samples showed a dip.
Dr. Greg Little, a psychologist who has taken an interest in this structure, confronted Shinn about this discrepancy and Shinn admitted he didn’t really take his study seriously. He said, “I got a little carried away to make a good story.”
