Lots of rare ancient objects can be found underground. Let's take a look at some of the rarest underground discoveries ever.
Archeologists and amateurs have made some incredible discoveries which can either reveal valuable information about the past or create entirely new mysteries. From 10 million-year-old teeth to thousands of baffling golden spirals, here are some of the most interesting ancient rare objects found underground.
10. Egyptian Sphinx
Everyone’s seen the Great Sphinx of Giza – the giant limestone statue depicting a mythical creature which combines the strength of a lion with the worldly might of a king – but Egyptian archeologists made a surprising new discovery in September 2018.
While draining groundwater from the Pharaonic temple of Kom Ombo near the southern city of Aswan, a team of archeologists uncovered an intact hidden Sphinx sculpture.
9. Danish Spirals
Archeologists in Denmark were truly baffled by the discovery of some bizarre Bronze Age objects during a series of digs in the area of Beoslunde in 2015. This nicknamed ‘golden enigma’ came in the form of 2,000 tiny spirals of tightly wound gold wires each no more than an inch in length, which if combined would make up ½ a pound of solid gold.

8. 10 Million-Year-Old-Teeth
The next highly controversial discovery was made in September 2016 at a fossil site in Eppelsheim in Germany, sparking a hotly debated conversation about the origin story of mankind. The unusual objects in the image below may look like dinosaur claws or insects fossilized in amber, but it is in fact two teeth believed to be around 9.7 million years old.
The well-preserved teeth were recovered from sediments, and their incredibly close resemblance to teeth belonging to a fossil of an early human ancestor known as Australopithecus Afarensis or ‘Lucy’ posed important questions about human history.7. Medieval Ring
It’s not always seasoned archeologists who make surprising underground finds, as proven by a 34-year-old man who made an astounding discovery after taking up amateur metal detecting as a hobby.
Mark Thompson had been scouring Sherwood Forest in Nottinghamshire for just 20 minutes in 2016 when a signal indicated that there was a hidden treasure below the dirt.
A gold sapphire stone ring discovered by an amateur treasure hunter and their metal detector in Sherwood Forest (the home of the legendary Robin Hood). It likely dates back to the 14th century.
6. Alien Aluminum
Back in 1974, builders working on the shores of the Mures River near the town of Aiud in Communist Romania happened across a strange object buried 33 feet underground, but the discovery was not made public until 1995 when it became the center of a controversial conspiracy.
The chunk of lightweight metal is just 7 inches in length and 5 inches in width with a thickness of 3 inches, but when testing revealed it was made from 90% aluminum, alarm bells sounded. The unrecognizable object was estimated to be a staggering 250,000 years old, but as metallic aluminum was not produced by mankind until just 200 years ago, this discovery became one baffling mystery.The ‘Auid Aluminium Wedge’ has remained unidentified over the years, but its distinct concavities seem to suggest it had been manufactured possibly as part of some larger piece of machinery.
5. Thracian Chariot
Karanovo in Bulgaria was the site of an exciting find for a team of archeologists who uncovered this rare find back in 2008. The image below reveals a 2000-year-old chariot from the Thracian era.
The wooden chariot was covered in bronze and would have been decorated with scenes from Thracian mythology which are now difficult to see in its decomposing state. Alongside the chariot were two complete horse skeletons as the animals which pulled the chariot would’ve been ceremoniously killed before the burial.And in 2009 the team made a further discovery. A brick tomb containing the remains of a man dressed in armor with several items like gold coins and a silver cup suggested that the body was a nobleman or ruler who was deliberately buried nearby.
4. Viking Sword
The Viking age is shrouded in legend and folklore, so any evidence of the lives of these ancient Scandinavian warriors is highly valued by archeologists. Surprisingly, a metal-detecting hobbyist from Loppi in Finland uncovered an astounding Viking sword on his own farmstead in September 2017.
3. Scottish Stone Balls
For more than 200 years, the bizarre objects in the image below have been puzzling archeologists from Ireland to Norway.
Over 500 of these extra-terrestrial-looking stone balls have turned up, with the most prolific area of discovery being the Orkney Islands and mainland Scotland, where the Scottish National Museum in Edinburgh houses the world’s largest collection.
2. Jackpot
Happening upon the biggest treasure trove in the history of Japan isn’t something archeologists can expect every day, but one team literally hit the jackpot in March 2018 when they made the incredible discovery in the image below.
This giant clay pitcher was unearthed in the city of Hasuda during excavations of the medieval epoch of the warring kingdoms during the second half of the 15th or 16th centuries and is thought to belong to a former Samurai. The 27-inch pot contained 260,000 copper coins which would have been connected by a rope through the characteristic hole in the middle of each coin at the time of burial sometime after the XV century.
Honorable Mention
Before we investigate the most amazing rare object, here’s an honorable mention: the Roman Dodecahedrons. If you thought the Scottish stone balls were baffling, these interesting ancient objects will blow your mind.
Around 100 of these strange artifacts dating back to the 2nd or 3rd century AD have been found over the years anywhere from Wales, Hungary, Spain, Italy, Germany and France. The Roman Dodecahedron can be identified by its 12 bronze or stone pentagonal faces each with a circular hole of varying size and knobs on each corner – but what does it all mean?As there is no mention of such an object in contemporary accounts or imagery, speculation has varied from candlestick holders, dice, knitting aid or even measuring tools – although the latter is unlikely as the dodecahedron is not standardized in size, ranging from 4-11cm.1. Ancient Boulders
In May 2015, German granite supplier VGB Natursteine made an incredibly rare discovery near the Bavarian Forest in the form of some seriously impressive buried stones. These giant ‘woolsack-weathered boulders’ range in size and shape with heights of almost 20 feet, the biggest of which weighed 72 tonnes and is over 1500 cubic feet in size.
Each boulder carefully removed from the quarry originated around 300 million years ago and was formed when a section of the planet's crust known as a ‘granite massif’ was displaced. Rainwater then penetrated the surface strata of this huge section of rock, decomposing the edges and corners of the topmost layers through a process of ‘spheroidal weathering’.
