In the search for buried history, archaeologists pour their resources into uncovering the remnants of the distant past. With know-how, persistence and a little luck, archaeologists can push aside dirt and rock and find an artifact of historical significance. Although chance plays a big role in unearthing history, archaeological treasures have been stumbled upon purely by accident, often by those outside the scientific community. In these photos, explore several particularly serendipitous finds of unique artifacts, some of which reach as far back as prehistory.
On Sept. 12, 1940, four teenagers followed their wayward dog into a cave complex near the village of Montignac in southwestern France. To their surprise, the caves hosted something remarkable: nearly 2,000 paintings and etchings of animals, humans and abstract shapes on the walls dating back between 15,000 and 25,000 years. Known as the Lascaux caves, the complex features figures depicted in surprising detail given the age of the illustrations. Animals portrayed on the cave walls included horses, stags, bison and felines. Archaeologists believed the caves were used for ritualistic purposes. Some parts of the illustrations even appear to construct a narrative, but what they mean exactly has yet to be deciphered. The caves were open to the public in 1948, but closed in 1963 in order to preserve the site from damage.
The Dead Sea Scrolls are a collection of over 800 biblical texts made of animal skin and papyrus. Dating to around 2,000 years ago, between the years 200 B.C. and 70 A.D., the scrolls could well be the oldest such documents in existence and have deepened historians' understanding of religious history. These documents may have been lost to history had a Bedouin shepherd named Muhammed edh-Dhib and his cousin not stumbled upon the first manuscripts along the northern shore of the Dead Sea at a remote site known as Qumran in 1947. The last fragments of the Dead Sea Scrolls collection was uncovered in the mid-1950s. Although the scrolls have been extensively studied and translated, one big mystery remains: Who exactly wrote them?
As Napoleon Bonaparte's army marched through north Africa during his campaign in Egypt, they stumbled upon what would become known as the Rosetta Stone, after the town where it was discovered. Within Bonaparte's army was a squadron of scholars called Institute of Egypt, also known as the Scientific and Artistic Commission. As the military settled around the Nile Delta, the Institute explored local ruins and artifacts. After the discovery of the stone in 1799, several copies of the inscriptions on its face were made, since no one could read them at the time. By 1802, the Greek and Demotic portions of the stone had been deciphered by scholars. The hieroglyphics posed a different challenge all together, however, and it would take 20 years before French scholar Jean-François Champollion announced that he had cracked the code. By deciphering the hieroglyphs, Champollion opened a whole new door to understanding the civilization of ancient Egypt. The Rosetta Stone is currently kept in the British Museum.
In case you don't know what a geoglyph is, ancient Peruvians went through the trouble of leaving a picture-perfect definition. Known as the Nazca Lines, these giant carvings into the Earth were only discovered by airplane in the 1930s. Located in the Nazva desert in southern Peru around 250 miles (400 kilometers) south of Lima, the geoglyphs resemble a number of animals including a spider (as seen here), a condor, a monkey, a tree, as well as human figures and geometric patterns. Why exactly indigenous tribes living in the area between 100 B.C. and 650 A.D. felt compelled to produce these works remains a mystery, though archaeologists agree that it is likely tied to religious customs.
In 1991, German tourists stumbled upon a frozen body in a glacier on the Ötztal Alps between Italy and Austria. Although they originally thought the corpse to be the result of a recent death, the iceman mummy, named Ötzi, in fact dated back 5,300 years. Since Ötzi's discovery, the mummy has been extensively studied. Scientists have learned everything from his last meal to his cause of death to his possible occupation and they have even made reconstructions of his face. Ötzi died in the spring as a result of an arrowhead striking his left clavicle artery. He likely received a ceremonial burial and was found beside tools and other personal items.
Over the years, metal detector enthusiasts, particularly those in the United Kingdom, have uncovered archaeological treasures buried beneath the Earth. In 2009, 30-year-old Nick Davies hauled in 10,000 ancient Roman coins that he had found inside a clay pot buried in Shropshire, U.K. That same year, a trove of 1,500 gold and silver pieces dating back to the Dark Ages were found on a farmer's field in the western region of Staffordshire, England. Last year, 63-year-old David Crisp uncovered 52,000 ancient Roman coins, later given a value of around $1 million, in a clay pot in southwestern England.

In 1986, divers stumbled upon a nearly 2,000-year-old Roman shipwreck some six miles off the coast of the town of Grado, Italy. Measuring 55 feet long and 16 feet wide, the small trade vessel was stocked with 600 amphorae, or vases, packed with sardines and other fish. Further study of the shipwreck revealed that the ancient Roman engineers also had built in a hydraulic system that allowed the ship to carry an aquarium with live fish.
New rock lines discovered in Peru predate the famous Nazca Lines by centuries and likely once marked the site of ancient fairs, researchers say.
The lines were created by people of the Paracas, a civilization that arose around 800 B.C. in what is now Peru. The Paracas culture predated the Nazca culture, which came onto the scene around 100 B.C. The Nazca people are famous for their fantastic geoglyphs, or rock lines, built in the shapes of monkeys, birds and other animals.
The new lines date to around 300 B.C., making them at least 300 years older than the oldest Nazca lines, said Charles Stanish, the director of the Cotsen Institute of Archaeology at the University of California, Los Angeles, who reported the new find today (May 5) in the journal Proceedings of the National Academy of Sciences.
"They used the lines in a different way than the Nazca," Stanish told Live Science. "They basically created these areas of highly ritualized processions and activities that were not settled permanently." [See Images of Ancient 'Nazca' Lines & Fair Site]
The closest European analog, Stanish said, would be the medieval fairs that brought visitors from far and wide.
Stanish and his team discovered the lines in the Chinca Valley, which is about 125 miles (200 kilometers) south of Lima, Peru. The area has a history of pre-European-contact settlements stretching from at least 800 B.C. to the 1500s A.D.
Archaeological surveys revealed large, ancient mounds in the valley. Over three field seasons, Stanish and his colleagues mapped these mounds, as well as nearby rock lines associated with each mound. They found 71 geoglyph lines or segments, 353 rock cairns, rocks forming circles or rectangles, and one point at which a series of lines converged in a circle of rays. The researchers also excavated one cluster of man-made mounds.
The excavations and mapping revealed a carefully built environment. Some long lines marked the spot where the sun would have set during the June solstice (the winter solstice in the Southern Hemisphere). Two U-shaped mounds also pointed toward the June solstice sunset, and the largest platform mound on the site lined up with the solstice as well. These lines and mounds probably served as a way to mark time during festivals, Stanish said.
"I don't think people needed the signposts, but it was more kind of a ritualized thing, where you come down and everything's prepared," he said.

Some lines are set out to frame pyramid structures, Stanish said. The lines are parallel, but because parallel lines seem to converge with distance, these framing lines appear to point directly at pyramids. Other lines run parallel to roads that are still used today, Stanish said.
The desert lines and mounds are about 9 miles (15 km) from settlements near the coast. Stanish and his colleagues suspect that the ancient "fairgrounds" were built on land that was useless for farming and were intended to attract tradespeople and buyers from the coast and the Andes highlands.
The mounds, pyramids and lines were likely the ancient version of neon signs, Stanish explained: "We're expending time and effort and resources to make our place bigger and better," he said, explaining the mindset of those who created the constructions. The various settlements on the coast probably competed to attract the most participants to their own fairs.
To confirm this notion, the researchers plan to excavate pyramids near the coast, looking for artifacts that would link settlements to the desert lines and mounds.
The discovery of these older rock lines emphasizes the geoglyphs had more than one function, Stanish said. People have long looked for "the" reason for the Nazca lines, but it's more accurate to think of the lines like multi-purpose technology, he said.
"The lines are effectively a social technology," Stanish said. "They're using it for certain purposes. Some people have said the lines point out sacred mountains. Sure, why not? The lines point out sacred pyramids. Why not? The lines could be used to point out processions," Stanish said of both the Nazca and Peru lines.
In that way, Stanish said, the lines are like pottery: one invention used for multiple purposes.
"Native Americans in this part of the world were extremely ingenious," he said.
