Museums are expansive institutions, often housing archives that span multiple warehouses. Given their immense size, it’s no surprise that valuable and rare artifacts occasionally go unnoticed or misplaced. From ancient sounds unheard for millennia to mysterious UFO artifacts likened to “Britain’s Roswell,” these remarkable pieces of history have been thankfully rediscovered.
10. A Statue of Alexander the Great Without a Nose

In 2019, while conducting an inventory at a storage facility of the Archaeological Museum of Veroia in Greece, archaeologists stumbled upon a marble statue partially concealed beneath other artifacts. Though missing its nose, the face was unmistakable—it was Alexander the Great.
The remarkable bust had been overlooked for years, hidden in the shadows of the warehouse. Originally unearthed in the remains of a Greek village, the statue bore more than just a missing nose. During the 18th or 19th century, it had been repurposed as construction material, embedded in a wall and coated with mortar. At the time of its initial discovery, researchers failed to recognize that the statue portrayed the legendary Macedonian king.
A recent analysis revealed that the artwork dates back to the second century BC, approximately two centuries after the death of Alexander the Great. The 2,100-year-old statue was meticulously restored and is now exhibited at the Museum of Royal Tombs of Aigai in Vergina.
9. A Colossal Sea Monster

In 2023, a researcher sifting through fossil collections at the Abingdon County Hall Museum in the UK stumbled upon an enormous vertebra. This unexpected find led to the identification of three additional vertebrae, all unearthed in Oxfordshire and estimated to be 152 million years old.
This was no ordinary Jurassic-era creature. Detailed scans of the fossils confirmed they belonged to a pliosaur, a terrifying marine predator resembling a mix between a crocodile and a turtle, equipped with paddle-shaped flippers and razor-sharp jaws. Notably, its bite force surpassed even that of a Tyrannosaurus rex.
Pliosaurs were apex predators that varied in species and size. This particular specimen, measuring between 32 and 47 feet (9.8 to 14.4 meters) in length, is the largest ever discovered, solidifying its place as one of the most formidable carnivores to have roamed the ancient seas.
8. A Strange Tale Involving Charles Dickens

Charles Dickens, the renowned author, found himself at the center of an unusual incident that he did not fabricate. It began with a letter he wrote on Christmas Eve in 1869, expressing his frustration with the Great Western Railway Company for failing to deliver his Christmas turkey. After inquiries, he discovered the bird had been lost in an unexpected fire.
This peculiar event might have remained unknown if not for a rediscovered letter at the National Railway Museum, where it had been overlooked for years. In the letter, Dickens graciously accepted the railway company’s apology and noted that he was handling the situation with a sense of humor.
Dickens might not have been as understanding had he been aware of two key details: this was his final Christmas turkey (he passed away months later), and railway staff had sold portions of the charred bird to locals for sixpence each.
7. The Counterfeit That Turned Out to Be Genuine

Some treasures remain hidden in plain sight. For years, the Field Museum in Chicago showcased a sword unearthed in the 1930s from the Danube River in Budapest. Labeled as a Medieval-era replica of a Bronze Age Hungarian weapon, it was long considered an ancient forgery.
In 2022, a Hungarian archaeologist visiting the museum immediately identified the sword as an authentic Bronze Age artifact. This revelation prompted the museum’s curator to conduct an X-ray analysis, which confirmed the sword’s composition of tin and copper matched that of genuine Bronze Age relics.
The 3,000-year-old sword was likely intentionally cast into the Danube River between 1,080 and 900 BC. During this period, it was customary to ritually deposit weapons into rivers to honor battles or commemorate the passing of loved ones.
6. The True Final Captive Thylacine

Contrary to popular belief, the last captive thylacine was not a male named Benjamin. In 1936, a female Tasmanian tiger was illegally captured and sold to the Beaumaris Zoo in Hobart, where Benjamin was also housed. She survived him but succumbed to exposure four months later. Her death went unnoticed as a historic moment—marking the end of thylacines in captivity forever.
As time passed, the truth emerged, but efforts to locate her remains proved futile. Concerns grew that her body had been discarded after death, potentially lost forever. However, in 2022, staff at the Tasmanian Museum and Art Gallery (TMAG) discovered an unpublished report indicating that her remains had been housed in their museum all along.
The report revealed that the remains had been donated to TMAG and stored in the museum’s educational section, not the zoological department where researchers had previously searched. Upon opening a cupboard in the educational archives, they found the preserved pelt and skeleton of the female thylacine. She had been used in school programs to teach students about thylacine anatomy before being archived in the 1980s.
5. Exceptionally Rare Pyramid Timber

In 1872, a cedar plank measuring 5 inches (13cm) was discovered inside the Queen’s Chamber of Egypt’s Great Pyramid. This artifact was one of only three items ever found within the pyramid, making its disappearance a significant loss.
A breakthrough came in 2001 when an archival record surfaced, indicating the fragment had been donated to a Scottish university. Despite knowing the institution’s name (the University of Aberdeen), the wood remained elusive.
By 2019, the artifact had been missing for 70 years. That same year, an assistant curator at the University of Aberdeen stumbled upon a cigar tin in their Asia museum collection. Inside were fragments of wood, later identified as the shattered Giza artifact. Testing confirmed the wood was 5,000 years old, suggesting it was used during the pyramid’s construction and left behind by its builders, not later visitors.
4. Sounds Silenced for 18,000 Years

In 2021, researchers unveiled the results of an unexpected discovery. While reviewing the inventory of the Natural History Museum of Toulouse in France, they came across an oversized seashell. Found in 1931 in the Marsoulas cave near the Pyrenees Mountains, the shell belonged to the Pyrenean Magdalenians, who inhabited the cave 18,000 years ago.
Initially mistaken for a communal drinking cup with a broken tip, further analysis revealed that the shell’s tip had been intentionally modified, with holes drilled and a mouthpiece added. This indicated it was, in fact, a musical instrument.
The team couldn’t resist testing the conch, and after 18,000 years of silence, it produced rich tones close to C, C-sharp, and D. This was just the first experiment, and the shell is believed to be capable of producing even more sounds. Notably, it is the oldest known musical shell of its kind.
3. The Silpho Moor UFO Incident

In 1957, three men stumbled upon an unusual object on Silpho Moor near Scarborough, later dubbed a “copper-bottomed flying saucer” by newspapers. Measuring 18 inches (45cm) in diameter and adorned with mysterious hieroglyphs on copper sheets, the artifact was deemed a hoax by experts. However, public fascination soared, earning it the dramatic title of “Britain’s Roswell.”
The fragments eventually vanished, only to resurface decades later. A man searching the Science Museum archives for files on aviation historian and UFO enthusiast Charles Harvard Gibbs-Smith discovered a cigarette tin containing metal pieces and a note labeling them as “alleged UFO bits.” These fragments closely matched descriptions of the 1957 Silpho Moor discovery.
The contents of the tin included several metal pieces and a note referencing “alleged UFO bits.” Given their striking resemblance to the 1957 Silpho Moor object, it’s highly likely they are remnants of the same artifact.
2. Footage Once Thought to Be a Legend

Film enthusiasts long whispered about the existence of a 1898 Mardi Gras parade film. If genuine, it would be the oldest moving footage of both the New Orleans Mardi Gras and the city itself. While many dismissed it as myth, Arthur Hardy was determined to uncover this cinematic treasure. After years of fruitless searching, he nearly abandoned hope.
However, Hardy’s persistence paid off when he contacted the Louisiana State Museum. The museum’s curator reached out to the Rex Organization, which oversees the Mardi Gras parade. An archivist from the organization eventually located the legendary footage in 2022 at the Eye Filmmuseum in Amsterdam.
The two-minute film captures six floats from the February 22, 1898, parade, themed “Harvest Queens.” One float featured people dressed as pineapples, while another showcased Rex, the “King of the Carnival.” A third float carried a live bull, a tradition discontinued in the early 20th century in favor of papier-mache replicas.
1. The Final Breath of Edison

While Henry Ford is celebrated for inventing the gas-powered car, fewer know he once worked as an engineer at Thomas Edison’s company. Their friendship spanned over three decades until Edison’s death in 1931. Grieving, Ford requested Edison’s son to capture his father’s last breath in a test tube as a keepsake.
Ford died in 1947, and his belongings were stored in boxes at the Henry Ford Museum in Michigan. Decades later, museum staff discovered the test tube and exhibited it. The tale of Edison’s “final breath” quickly captivated public imagination.
The truth behind the legend remains unclear. While Edison’s son did present Ford with the tube, it’s unknown whether it captured Edison’s last breath or was simply an empty container from the room where he passed away.
