The bone of a large extinct creature, once treasured by the ancient Greeks, has finally found a permanent home in England.

Known as the Nichoria bone, the blackened fossil is part of the thigh bone of an immense extinct mammal that roamed southern Greece perhaps a million years ago. The bone was collected by ancient Greeks and may have even helped inspire certain beasts in Greek classical mythology. It was then rediscovered 40 years ago.

Since then the fossil had largely vanished from the public eye.

"It was presumed lost until 1998. Following my inquiries, the fossil was found stored in a cellar at the University of Minnesota. It then spent the last decade in various U.S. labs," Adrienne Mayor, a research scholar in Classics and History of Science at Stanford University, told Discovery News.

The historic fossil has been welcomed by curators at the Ashmolean Museum in Oxford, England.

"This venerable bone deserves to be displayed. It is one of only two large vertebrate fossils that were deliberately collected in antiquity and unearthed by archaeologists in Greece," Mayor said.

Large fossil remains of prehistoric species, like this petrified thigh bone, might have been the inspiration for many legendary beasts of classical mythology, according to Mayor, who described the fossil for the first time in her 2000 book "The First Fossil Hunters."

Uncovering the roots of several myths, the book, whose revised edition has been published this month, showed that prehistoric fossils exist in the very places where myths about giant beings arose.

"Most likely, the ancient Greeks found the bone in the lignite deposits of the Megalopolis basin, known in antiquity as the 'Battleground of the Giants.' There, the dense concentration of large fossil bones inspired the belief that entire armies of giants were blasted by Zeus's thunderbolts," Mayor told Discovery News.

Perhaps revered as the thigh bone of a mythic giant, the Nichoria bone was discovered on the ancient acropolis at Nichoria between 1969 and 1975 by archaeologists of the Minnesota Messenia Expedition.

The fact that it was carefully stored on the acropolis, which stood some 35 miles from the lignite deposits where the bone was probably found, shows that the ancient Greeks had a great interest in fossils.

"The bone provides further confirmation that the ancient Greeks already found such specimens and ascribed special significance to them," Hans-Dieter Sues, senior scientist and curator of vertebrate paleontology at the Smithsonian's National Museum of Natural History in Washington, D.C., told Discovery News.

Identified in 1978 as the femur of a "Pliocene elephant," the bone was lost for two decades. Rediscovered in 1998 in the Archaeometry Laboratory of the University of Minnesota, Duluth, it remained uncataloged until Mayor recognized its significance.

She took the fossil to the American Museum of Natural History in New York, where it was examined by paleontologist Nikos Solounias, an expert in Greek fossils of the Miocene to Holocene epochs.

Solounias identified the bone as the distal end of the femur of a woolly rhinoceros, or possibly a Chalicotherium, a large herbivore, and dated it to the Pleistocene era (2 million to 10,000 years ago).

According to Solounias, the rusty-black color of the fossil bone indicates that it was most likely collected from the lignite deposits near the ancient town of Megalopolis. Carried by the ancient Greeks to the sunny acropolis of Nichoria, and then unearthed two millennia later, the bone traveled extensively in the last decade.

From Greece, across the Mediterranean and Atlantic, it went to Minnesota, then east to Princeton, New Jersey and New York City to be identified by paleontologists. Then west again to Bozeman, Mont., where it was professionally stabilized by restorers at the Museum of the Rockies, to prevent further breakage.

"It was then transported overland to Palo Alto, Calif., where it rested on my desk, as I searched for a proper home in a leading museum," Mayor said.

This spring, the relic traveled back over the Atlantic, from California to its final home at the Ashmolean Museum in Oxford, where it will be displayed in the Greek and Roman Antiquities Gallery.

Explainer: Seven real-life archaeological mysteries

  • Alexandre Meneghini  /  AP file

    Hollywood's favorite archaeologist has chased around Egypt, India, the Middle East ... and the Amazon as well. "Indiana Jones and the Kingdom of the Crystal Skull" is loosely inspired by a supposed Mesoamerican legend that 13 widely dispersed crystal skulls will yield unprecedented powers when united.

    In real life, several purported crystal skulls are housed in museums around the world, though archaeologists doubt their ancient provenance and mystical powers. Instead, these skulls are primarily seen as fakes sold by 19th-century antiquities dealers to feed a market hungry for pre-Hispanic relics. Nevertheless, the archaeological mystery of the crystal skulls lives on. Skull hunters still search for them, and the Maya believe they hold special powers. In this picture, a priest hoists a skull in a ceremony at the Palenque ruins in Mexico.

  • Where is the grave of Genghis Khan?

    Where is Genghis Khan buried? Nobody knows. The bloody Mongol warrior became famous as the ruler of an empire that eventually stretched from China to Hungary, but he asked to be buried in an unmarked grave. According to legend, anyone who witnessed the burial party en route to the funeral in 1227 was killed, and then the soldiers and servants who attended the funeral were massacred. Thus, the grave site has been one of archaeology's enduring mysteries. But scientists may be closing in on the location at last. In 2004, they unearthed the site of Genghis Khan's 13th-century palace, which is pictured here. Ancient texts suggest the grave itself could be nearby.

  • What happened on Easter Island?

    Hundreds of monolithic statues called Moai, including the ones in this picture, ring remote Easter Island in the South Pacific. They face inland from the shore, presumably keeping watch over ancestral lands. Scientists unraveling the mystery of how the Polynesian settlers moved the statues are also piecing together the tale of the settlers' demise. According to a leading theory, giant palms were hacked down to roll the statues into place beginning in about 1200. As the population swelled, more chiefs requested statues, and more trees were felled. Eventually the island was denuded. Easter Island's environment — and society — collapsed. Other researchers pin the blame on Europeans, disease and rats.

  • Was Stonehenge a place of healing?

    Every year at the summer solstice, thousands of people witness the season's first sunrise at Stonehenge, about 90 miles west of London in the English countryside. Was the monument erected beginning around 3000 B.C. for the secular purpose of marking time? Perhaps, some scholars say. Another prominent theory suggests it was a place of worship. The most recent idea holds that the monument was erected as center of healing. Archaeologists dug at the site for the first time in nearly half a century to get a precise date for Stonehenge's bluestones, which were thought to have healing powers. A close match with the time frame during which archaeologists believe the stones were taken from the Perseli Mountains, 153 miles away, could help confirm the theory.

  • Why were the Nazca Lines etched?

    Hundreds of lines and figures etched into the coastal desert of southern Peru have baffled archaeologists for decades. The Nazca people made the playing-field sized etchings between 200 B.C. and A.D. 700 by removing rust-colored pebbles to reveal the lighter soils beneath. Some are simple shapes reminiscent of geometry class. Others are recognizable animals, such as the hummingbird in this image. But what do they mean? Theories proposed over the years have ranged from religious and astronomical purposes to guideposts of sorts for finding water.

  • What is China's terracotta army guarding?

    In 1974, archaeologists found an army of thousands of terracotta statues standing guard outside the tomb of Qin Shi Huang Di, the ruler who unified China in 221 B.C. The find ranks as one of the greatest archaeological discoveries of the 20th century. Each of the soldiers has a unique facial expression, and the troops are aligned according to rank in trenchlike corridors, accompanied by horses and chariots.

    As impressive as the army may be, scientists suspect that even greater treasure lies within Qin's unexcavated tomb. An account by an ancient court historian suggests that the tomb is full of miniature palaces, rivers of mercury and precious stones to represent the moon and stars. Remote sensing and nearby excavations have lent some credence to the writings.

  • How were the Egyptian pyramids built?

    The Great Pyramid of Giza near Cairo, one of the ancient Seven Wonders of the World, retains its world-famous status in a 21st-century list of seven wonders. Its mystique partly rests in just how the 479-foot-tall burial structure was built. Most Egyptologists believe large stones were moved from a quarry and lifted into place, but how? Teams of workers could have dragged the 2.5-ton stones with brute force, or perhaps they rolled them on logs. However they did it, recent research suggests the workers were skilled, not untrained slaves.
