Archaeologists revealed more wonders of the ancient world in 2021.
They ranged from a lost city, a mummy with a golden tongue, and 2,400-year-old baskets of fruit.
We document some of the best archaeological finds of the last 12 months.
In 2021 archaeologists discovered an array of lost treasures of the ancient world.
Insider's coverage of the archaeological breakthroughs included Egyptian mummies with tongues of gold, sunken Crusader trove, and 2000-year-old Roman slave quarters perfectly preserved by a volcanic eruption.
2,400-year-old baskets of fruit discovered in ancient Egyptian city under the sea
In August 2021, Insider's Alia Shoaib reported that 2,400-year-old baskets of fruit were discovered in an ancient Egyptian under-sea city Thonis-Heracleion.
Archaeologists found a trove of ancient artifacts from the fourth century BCE, including wicker baskets filled with doum, fruit from an African palm tree, grape seeds, and Greek ceramics.
The fascinating discovery was made by a team of researchers from the European Institute for Underwater Archaeology, led by the French marine archaeologist Franck Goddio, who discovered the ruin of Thonis-Heracleion twenty years ago.
Goddio told the Guardian that the fruit had been untouched for over 2000 years, calling the find "incredible."
Archaeologists discovered 2 ancient graves of a mother and baby near Stonehenge in England
In February, Archaeologists in England found two ancient graves near the prehistoric Stonehenge in Salisbury.
The find was made during excavations necessary before the creation of a new highway tunnel.
The two graves were declared to be roughly 4,500 years old - as old as the stones in the central circle of the henge - and belonging to a mother and baby.
The pair were thought to be related to those who built the circle, with Matt Leivers, an archaeologist with Wessex Archaeology who helped survey the area having told Insider: "The later arrangements of bluestones would have been built around the time these people lived and died - if they weren't the builders then they might have been their relatives, or perhaps their children or grandchildren."
Stonehenge has been a mystery for centuries - until February 2021, when researchers discovered the stones had been transported from Wales to Salisbury, suggesting the henge is a type of burial ground.
'Lost golden city' found in Egypt
In April 2021, Jacob Sarkisian reported that a "lost golden city" was found in Egypt, 300 miles south of Cairo.
It was one of the largest ancient cities ever discovered in the country and one of the most significant finds since the discovery of Tutankhamun's tomb a century ago.
The team said in a statement: "The Egyptian mission under Dr. Zahi Hawass found the city that was lost under the sands. The city is 3,000 years old, dates to the reign of Amenhotep III, and continued to be used by Tutankhamun and Ay."
The city features several neighborhoods, intact 10-feet-high walls, and even a bakery.
The earliest evidence of tobacco used by hunter-gatherers in the US West 12,000 years ago
At the beginning of October 2021, Joshua Zitser reported that the earliest evidence of tobacco use was found in Utah.
The find dates back over 12,000 years, with the leaf believed to be used by hunter-gatherers for food preparation.
This uncovered the fact that humans may have been using tobacco some 9,000 years earlier than previously thought.

An amateur diver found a 3-foot sword off the Israeli coast dating back to the Crusades
In October 2021, an amateur diver in Israel made an incredible find: a three-foot crusade-era sword.
Shlomi Katzin came across a giant sword, covered in shells and marine life, 13 feet under the Mediterranean waves as he was exploring the waters of the Carmel coast.
Katzin also found giant metal and stone anchors and bits of pottery nestled in a 1,000 square-foot patch of the sandy seabed during his exploration.
Katzin reported his find to the Israel Antiquities Authority, and they declared the sword to be from between the 11th and 13th centuries.
"It is exciting to encounter such a personal object, taking you 900 years back in time to a different era, with knights, armor, and swords." Nir Distelfeld, an inspector for the IAA's Robbery Prevention Unit, said in a press release.

Archaeologists discovered an Egyptian mummy buried with a golden tongue
In February 2021, archaeologists in Egypt uncovered a mummy buried with a golden tongue in its mouth.
Egyptian and Dominican archaeologists found 16 burial shafts at the Taposiris Magna Temple near Alexandria. When searching the places of rest, they found one mummy who was given a golden amulet in the shape of a tongue placed in its mouth.
The amulet is a great honor, thought to give the dead the ability to speak to gods.
Rare evidence of Roman crucifixion found in England
In December 2021, Insider's Rebecca Cohen and Erin Schumaker reported that a skeleton in England was found with a nail through its foot - rare evidence of Roman crucifixion.
Researchers in Cambridgeshire were analyzing findings from a dig of an ancient Roman settlement, and when they researched the bones found, they discovered this evidence of crucifixion.
While crucifixion was thought to be relatively common for the Roman era, few pieces of evidence for it exist.
The find is just the fourth known crucifixion in the world, with it ranking as the best-preserved one.
Astonishing images of Roman slave quarters in Pompeii frozen in time for almost 2,000 years by a volcanic eruption
In November 2021, archaeologists in Pompeii, Italy, found incredibly well-preserved 2000-year old slave quarters.
The room, frozen in time due to the Mount Vesuvius eruption of 79 AD, featured beds, a chest, and a chamber pot.
Gabriel Zuchtriegel, director-general of Pompeii's archaeological park, hailed the findings on the Pompeii website as a "window into the precarious reality of people who seldom appear in historical sources."
High-tech scanners 'unwrapped' a mummified Egyptian pharaoh, revealing a seemingly healthy 35-year-old with no clues for how he died
Just as 2021 closed, Insider's science reporter Dr. Marianne Guenot reported how 3D CT scanners had been used to 'unwrap' a mummified Egyptian pharaoh.
The images showed "unprecedented detail" of the body of Amenhotep I, said Sahar Saleem, a professor of radiology and lead author of a study on the mummy.
Amenhotep was the second Pharaoh of Egypt's 18th dynasty, ruling for over two decades in 1525 BC.
The scans were able to age the Pharaoh and tell that he was 5 feet, 6 inches, tall, circumcised, had a narrow chin, a small narrow nose, curly hair, mildly protruding upper teeth, and a pierced left ear.
The discovery of a 2000-year-old dagger was a vital clue to revealing a forgotten battle between the Roman Empire's legions and tribal warriors
In Switzerland, a volunteer archaeologist uncovered a Roman-era dagger that has revealed intricate details of an ancient battle.
Schmid unearthed the dagger in the mountainous Graubünden region of Switzerland, an area believed to be the site of a lost battlefield where Imperial Roman soldiers fought Rhaetian warriors in approximately 15 BC.
This discovery then sparked further explorations, revealing a battlefield.
The dagger, dated to around 15 BC, is a rare find. The team behind the discovery explained that only four of its kind had ever been found in former Roman territories.
