Very little is known about funerary practices in Iron Age Britain, since few human remains have survived. However, the environment in northwest Scotland is more conducive to preserving bone from that period. Archaeologists have previously noted evidence of postmortem manipulation of human remains, such as mummification, and of modifying human bones into tools or decorative artifacts. Now a new paper published in the journal Antiquity describes evidence of postmortem brain removal in remains from that region, as well as sharpened limb bones, possibly for use as tools.
The remains in question were found in 2000 at a burial cairn in Loch Borralie, near the most northwest tip of the Scottish mainland, after erosion revealed a human cranium. The excavated remains belonged to two individuals: one an adult female and the other a juvenile of (at the time) indeterminate sex; the cranium belonged to the latter. The authors of the new paper conducted a fresh osteoarchaeological analysis as well as multi-isotope and ancient DNA analysis. Radiocarbon dating of molar teeth from both sets of remains placed their deaths as occurring between 50 BCE and 70 CE.
In the case of the female individual, the authors noted an unusual break at the base of the cranium that likely occurred near the time of death. It's the kind of fracture that one gets from high-velocity impacts, including vehicular collisions, sporting accidents, falls, assaults, or even long-drop hanging. But the known forensic patterns observed in the aforementioned scenarios don't exactly match the pattern of the Iron Age cranium, leading the authors to conclude that it likely resulted from a targeted impact. They also noted perimortem fractures on both scapulae.

At Kurd Qaburstan, an ancient site in the Kurdistan region of Iraq, archaeologists have uncovered the first substantial group of cuneiform administrative tablets found in the Erbil region, along with evidence of large-scale destruction, mass graves and citywide fortifications. Together, the discoveries are providing one of the clearest archaeological records yet uncovered of siege warfare and urban life during the Middle Bronze Age.
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt event, is still debated. Even more uncertain is how and when humans went from being "archaic" to "modern."
A remarkable archaeological discovery in Slovakia is changing what scientists thought they knew about life and death in some of Europe’s earliest farming communities. Since 2022, researchers have been excavating a 7,000-year-old settlement near the modern town of Vráble. What they found was startling: dozens of human skeletons piled together in and around a ditch, […]
A curious recent discovery has revealed a promising new underground archaeological find at the ancient site of Buto in Egypt’s Nile Delta.
Researchers who were testing a remote sensing technology designed to locate buried structures and other below-ground features reported the unique find earlier this year, which could be a previously undiscovered tomb or temple now believed to date as far back as 2,600 years.
The discovery was made at the Tell el-Fara’in site, more commonly known as Buto, which comprises the remains of an ancient city that thrived around 5,600 years ago during Egypt’s Predynastic period.
Origins of a Mystery
Buto underwent several periods of destruction and reassembly throughout its history, making it a significant focus of past archaeological work.
Some of the city’s oldest portions are currently entombed beneath several centuries’ worth of accumulated mud and soil, a factor that significantly complicates traditional excavations. To help them locate an ideal location for future excavation, the team employed an approach that combined SAR (Sentinel-1 GRD) satellite imagery with electrical resistivity tomography (ERT) measurements, which helped them pinpoint an ideal location to dig that would best enable an investigation of Buto’s settlement phases.
“Sentinel-1 (C-band) satellite imagery captured on May 5, 2018, was processed using SNAP software (version 9.0.0) to identify large-scale anomalies indicative of buried structures,” the team reports in a paper detailing their findings, which appeared in Applied Geophysics in March.
“Based on these detected anomalies, the locations for ERT profiles were strategically selected to maximize the likelihood of indicating significant subsurface features,” the team explained.
ERT technology is ideal for such carefully targeted excavation, since it relies on electrical currents placed into the ground, which researchers then use to collect data that helps them assemble a three-dimensional model of the buried structures. This imagery is generated based on differences in the way various materials either display electrical conductivity or resistance.
Buried Discoveries Emerge
Based on the team’s scans, the top three meters of the area revealed a distinctive layer of material, which the team judged to be broken pottery and debris—likely associated with Roman periods of occupation.
However, going further down in their scans, descending to a depth of approximately six meters, the team discovered something more intriguing: what appeared to be some kind of large buried structure.
Based on its depth, the team believes this unique structure is likely associated with the Saite period, which dates it to around 2,600 years ago. Although it remains unknown precisely what the structure is, or what its exact purpose may have been, one possibility is that it could be a large shrine, or even a tomb.
Uncovering Religious Artifacts
Following the initial discovery, the team undertook preliminary excavations of a small 10 x 10-meter area. This revealed walls constructed of mudbrick, as well as religious artifacts in locations that aligned with the team’s scans.
“The presence of a small offering basin along with numerous religious amulets depicting Egyptian deities such as Isis, Horus, Taweret, and Wadjet further supports the temple hypothesis,” the team writes in their study.

Also among the religious artifacts uncovered at the site were a “remarkable bronze amulet with a suspension hole, representing Horus the child” as well as amulets featuring a crouching lion, an amulet of Anubis, and the remains of limestone statues “in sexual positions” along with “a faience plaque with relief carvings of Hathor on both sides.”
However, the team reports that one of the most significant artifacts recovered from this area of the excavation was a steatite scarab bearing the name of King Thutmose III, which the team believes “may have functioned as an amulet or seal.”
“Collectively, these artefacts indicate the presence of a religious site with strong cultic and ceremonial associations, further reinforcing the interpretation of the structure as a temple from the 26th Dynasty,” the team says.
Ongoing Excavations
While still in the early phases, the team’s discoveries so far help to validate the geophysical and remote sensing techniques that made the discovery possible. “The results of this study demonstrate the effectiveness of combining geophysical measurements and remote sensing data,” the team writes, adding that they provided “a very accurate vision in detecting buried settlements in a complex region.”
“3D inversion algorithms were particularly effective in delineating buried mudbrick walls and architectural structures, significantly enhancing our understanding of site formation processes,” the researchers add.
Going forward, the team recommends further ERT surveys, which may help to reveal additional information about the site’s deepest occupation levels. For the time being, the team believes the evidence in hand points to the interpretation of the site and its features as an ancient temple, and that evidence points to the possibility that another may be located nearby.
“Our findings suggest that, in addition to the known temple, another temple may remain buried under a thick clay layer, which will be investigated through extensive measurements in forthcoming studies,” the team writes.
The recent paper, “Multi-scale detection of buried archaeological elements across different occupation phases: an integrated approach using radar satellite imagery and electric resistivity tomography at Buto, northwestern Nile Delta of Egypt,” appeared in Applied Geophysics on March 10, 2026.

A new analysis of 2,000-year-old skeletons found in northern Scotland has revealed an unusual funeral ritual involving the manipulation of dead bodies.
It is difficult to identify funerary practices in Iron Age (c. 800 BC–AD 43) Britain, as human remains rarely survive. However, evidence is particularly prominent in north-west Scotland, because environmental conditions support the preservation of bone. To take advantage of this, a team of researchers from the U.K. and U.S. examined two individuals (one adult female and one juvenile male) buried in a low stone cairn at Loch Borralie in Sutherland, close to the north-west extremity of the Scottish mainland.
New radiocarbon dates from Sala Keimada, a hard-to-reach chamber of Cueva Palomera in the province of Burgos, northern Spain, suggest that generations of people returned to the sacred space from the end of the Ice Age through the Iron Age, leaving behind art, structures and offerings.
Archaeologists excavating Maya sites at Kaxil Uinik and Ayiin Winik in Belize have discovered the first reported Late Postclassic altar in the region, along with additional evidence that Postclassic Maya people continued to visit abandoned locations. The study, published in Latin American Antiquity, indicates that these activities fit into a broad pattern of Postclassic veneration of earlier Maya civilization after its decline.
In 1925, while exploring the remote jungles of the Amazon on a quest to uncover a fabled lost city, British explorer Percy Fawcett and his small expedition party vanished without a trace.
Fawcett, a noted geographer, artillery officer, cartographer, surveyor, and archaeologist, set off into the rainforest accompanied only by his son, Jack Fawcett, and Jack’s best friend, Raleigh Rimell. Their goal was to locate an ancient lost city rumored to exist in the heart of the Amazon that Fawcett and others called “The Lost City of Z.”
While Fawcett and his expedition crew’s fate remains unknown, new advancements in modern archaeological science, propelled by technologies that include unmanned aerial vehicles and LiDAR, are now revealing what could be the archaeological reality behind part of what the ill-fated British explorer sought.
“The reward is that we’re finally finding the ‘lost civilisation’ that explorers like Percy Fawcett were searching for a century ago,” says José Iriarte, a professor of archaeology at the University of Exeter, writing in a piece featured at The Conversation, though adding that such discoveries are now being made “by cajoling a drone rather than battering through jungle.”
LiDAR: Unearthing Lost Worlds Hidden from Time
For a time, archaeologists presumed that the Amazon rainforest was a vast wilderness that, while abundant in resources, would have been capable of supporting only small, scattered communities.
With the aid of modern technologies, those past ideas have gradually changed as new archaeological evidence continues to push researchers toward rethinking past assumptions. Among these technologies is advanced laser-mapping technology known as LiDAR (light detection and ranging), which archaeologists have put to great use in the last several decades to aid in uncovering evidence of surface features that were once either inaccessible or otherwise invisible during ground-based surveys.
Something else that LiDAR excels at is penetrating the dense forest of areas like the Amazon, enabling researchers to get unprecedented aerial views of the surface below the canopy, along with any structures that may have been left there by humans from long ago. The result has been evidence of sprawling ancient societies hidden beneath the cover of thick jungle, revealing the Amazon as a region that once supported large populations that existed in sophisticated, interconnected landscapes.

Rediscovering a ‘Lost Civilization’ in the Amazon
A particularly striking example of such discoveries involves the Llanos de Moxos region of northern Bolivia, where recent LiDAR surveys have revealed the presence of a sprawling archaeological site long hidden by dense jungle. Archaeologists believe the ancient settlement is linked to what is called the Casarabe culture, which would have thrived in the area sometime between A.D. 500 and 1400.
“The Casarabe organized into a hierarchy of four different sizes of settlements,” writes Professor Iriarte in his recent piece at The Conversation. “The biggest ones—the primary settlements—were as large as 3km² or 300 hectares.”
“That’s enough space for over 400 football pitches,” Iriarte notes, “suggesting that they could have accommodated substantial numbers of people.”
Unseen Evidence of an Ancient Amazonian Culture
Viewed from the ground, an observer who braved this dense region of Bolivian jungle might only see thick patches of forest separated by grassland savannahs.
That all changes when viewing LiDAR imagery obtained during aerial surveys, however. Through the sensitive detection capabilities afforded by laser pulses that can easily penetrate the dense vegetation, a lost world emerges—one the likes of which Percy Fawcett and other early explorers once only dreamed of rediscovering.
Researchers have now successfully identified a vast network of settlements at Llanos de Moxos, connected by raised causeways, canals, reservoirs, and engineered agricultural systems that cover an area of close to 20,000 square kilometers.
These complexes upend past thinking about the presence of isolated settlements in the region, and instead appear to show sites covering areas as large as three square kilometers, featuring monumental civic and ceremonial architecture, towering conical pyramids that ascend to heights of 20 meters, and the presence of massive U-shaped structures, which archaeologists believe had likely served as ceremonial structures that once hosted gatherings.
Unprecedented Scale of a Hidden World
Another surprising feature is the scale of the structures archaeologists have uncovered, which they say rivals some of the most well-known monuments like those of the ancient Tiwanaku civilization in the Andes.
Yet, unlike many densely packed ancient cities, the Casarabe landscape also differs in several ways: the unique variety of urbanism it reflects is suggestive of dispersed populations whose connected infrastructure also brought them together through ancient shared water management systems.
“It was clearly all planned and coordinated,” Iriarte explains, adding that the ancient builders at Llanos de Moxos engaged in precocious designs that were intended “not only as living spaces but for integrating the population across the region.” Similar architectural planning has been observed at other ancient sites around the world, which include those assembled by the ancient Maya of Central America, as well as the builders of Angkor across the world in Cambodia.
The “Dark Earth” Enigma
Beyond just architecture and clues to the way of life of these ancient societies, researchers are also gaining new insights into the agricultural practices of the early Amazonian world.
For many decades, scientists presumed that a major limiting factor on the region’s ability to sustain larger populations hinged on the presence of factors that included poor soils, seasonal flooding, droughts, and tropical diseases. However, mounting evidence suggests that the indigenous societies of the region were far from hindered by the landscape, and instead managed to transform and manage farmland at scales previously unimagined.
Along with sophisticated agricultural systems, ancient Amazonians were also capable of engineering remarkably fertile soils, known as Amazonian Dark Earths, which Iriarte says “combined charcoal, bone and waste materials with the existing poor-quality soil to make it fertile enough for widespread farming.”
“Amazonia had reclaimed vast expanses of seasonally flooded savannahs over several thousand years to create raised and drained field systems,” he adds, also noting the construction of extensive drainage networks and the cultivation of diverse crops such as maize. Rather than merely adapting to the rainforest, the ancient inhabitants of the Amazon actively reshaped it.
An Amazonian Archaeological Revolution
Thanks to similar LiDAR surveys that have recently been undertaken in nearby countries, including Ecuador’s Upano Valley, where thousands of structures linked by roads and organized according to highly structured settlement plans have been detected, the recent findings at Llanos de Moxos are one of the latest additions to a broader revolution in archaeology made possible through such exciting Amazonian discoveries.
In addition to Bolivia and Ecuador, researchers have also documented ceremonial earthworks, geometric enclosures, and sprawling ancient settlements in Colombia, Peru, and Brazil in recent years, all of which are challenging decades of past assumptions about ancient life in the Amazon.
Despite the recent advancements in our understanding, many questions remain unanswered. Among the questions archaeologists have are those related to how these ancient societies were governed, as well as what factors led to their decline, a fall which was precipitated by unknown factors that occurred before European arrival.
Possible contributing factors may include shifts in ancient climates, as well as environmental pressures. It is also possible that political changes or conflicts that emerged between neighboring societies may have played a role, which could have contributed to disruptions in trade networks that may have further weakened these once thriving societies.
Despite the remaining mysteries about these enigmatic cultures, one thing is becoming increasingly clear: the Amazon was far from being the unclaimed tropical wilderness many long believed it to be. In many ways, the fascination with lost cities and ancient civilizations that drove explorers like Percy Fawcett—and which led to his untimely fate—had more basis in reality than many historians, archaeologists, and explorers probably guessed.
As ongoing LiDAR surveys continue to expand across previously unexplored regions, archaeologists believe thousands more structures may still await discovery, suggesting that some of the Amazon’s greatest archaeological secrets remain hidden, but no longer kept entirely from view.
“What lies beneath the Amazon is not just a hidden past,” Iriarte says. “It is a reminder that even the most seemingly untouched landscapes can carry deep histories, waiting—sometimes just beneath our feet—to be revealed.”

A study led by a UAB research team of Biological Anthropology has analyzed the genome of 54 newborns with the aim of tracking the genetic history of their culture since it developed in the Early Iron Age until the start of the Roman period, some 2,700 to 2,100 years ago.
Archaeologists working at the ancient Maya site of El Palmar in Campeche, Mexico, have discovered what may be the earliest known Long Count calendar date in the Maya lowlands. It is carved into a stone monument and is interpreted as Aug. 31, AD 180, in our modern calendar. The finding could reveal insights into how the earliest Maya rulers used time to stake their claim to the throne.
