What did Homo sapiens eat 170,000 years ago? Roasted, supersized land snails
Small groups of people roasted and ate large land snails, much like this modern land snail, at a rock-shelter in southern Africa starting around 170,000 years ago, a new study finds.

Slow-motion large land snails made for easy catching and good eating as early as 170,000 years ago. Until now, the oldest evidence of Homo sapiens eating land snails dated to roughly 49,000 years ago in Africa and 36,000 years ago in Europe. But tens of thousands of years earlier, people at a southern African rock-shelter roasted these slimy, chewy — and nutritious — creepers that can grow as big as an adult’s hand, researchers report in the April 15 Quaternary Science Reviews.

Analyses of shell fragments excavated at South Africa’s Border Cave indicate that hunter-gatherers who periodically occupied the site heated large African land snails on embers and then presumably ate them, say chemist Marine Wojcieszak and colleagues. Wojcieszak, of the Royal Institute for Cultural Heritage in Brussels, studies chemical properties of archaeological sites and artifacts.

The supersized delicacy became especially popular between about 160,000 and 70,000 years ago, the researchers say. Numbers of unearthed snail shell pieces were substantially larger in sediment layers dating to that time period.

New discoveries at Border Cave challenge an influential idea that human groups did not make land snails and other small game a big part of their diet until the last Ice Age waned around 15,000 to 10,000 years ago, Wojcieszak says.

Long before that, hunter-gatherer groups in southern Africa roamed the countryside collecting large land snails to bring back to Border Cave for themselves and to share with others, the team contends. Some of the group members who stayed behind on snail-gathering forays may have had limited mobility due to age or injury, the researchers suspect.

“The easy-to-eat, fatty protein of snails would have been an important food for the elderly and small children, who are less able to chew hard foods,” Wojcieszak says. “Food sharing [at Border Cave] shows that cooperative social behavior was in place from the dawn of our species.”

Border Cave’s ancient snail scarfers also push back the human consumption of mollusks by several thousand years, says archaeologist Antonieta Jerardino of the University of South Africa in Pretoria. Previous excavations at a cave on South Africa’s southern tip found evidence of humans eating mussels, limpets and other marine mollusks as early as around 164,000 years ago (SN: 7/29/11).

Given the nutritional value of large land snails, an earlier argument that it was eating fish and shellfish that energized human brain evolution may have been overstated, says Jerardino, who did not participate in the new study.

It’s not surprising that ancient H. sapiens recognized the nutritional value of land snails and occasionally cooked and ate them by 170,000 years ago, says Teresa Steele, an archaeologist at the University of California, Davis who was not part of the work. But intensive consumption of these snails starting around 160,000 years ago is unexpected and raises questions about whether climate and habitat changes may have reduced the availability of other foods,  Steele says.

Researchers have already found evidence that ancient people at Border Cave cooked starchy plant stems, ate an array of fruits and hunted small and large animals. The oldest known grass bedding, from around 200,000 years ago, has also been unearthed at Border Cave (SN: 8/13/20).

Several excavations have been conducted at the site since 1934. Three archaeologists on the new study — Lucinda Backwell and Lyn Wadley of Wits University in Johannesburg and Francesco d’Errico of the University of Bordeaux in France — directed the latest Border Cave dig, which ran from 2015 through 2019.

Discoveries by that team inspired the new investigation. Excavations uncovered shell fragments of large land snails, many discolored from possible burning, in all but the oldest sediment layers containing remnants of campfires and other H. sapiens activity. The oldest layers date to at least 227,000 years ago.

Chemical and microscopic characteristics of 27 snail shell fragments from various sediment layers were compared with shell fragments of modern large African snails that were heated in a metal furnace. Experimental temperatures ranged from 200° to 550° Celsius. Heating times lasted from five minutes to 36 hours.

All but a few ancient shell pieces displayed signs of extended heat exposure consistent with having once been attached to snails that were cooked on hot embers. Heating clues on shell surfaces included microscopic cracks and a dull finish.

Only lower parts of large land snail shells would have rested against embers during cooking, possibly explaining the mix of burned and unburned shell fragments unearthed at Border Cave, the researchers say.

Bronze Age and Roman-era settlements unearthed in Newquay

Bronze Age and Roman-era settlements unearthed in Newquay

Archaeologists from the Cornwall Archaeological have uncovered ancient dwellings from the Bronze Age and a Roman period settlement in Newquay, England.

The discovery was made at the site of a new housing development in Newquay.

The excavations team found three Bronze Age roundhouses and a Roman-period settlement – consisting of an oval house, a large processing area (thought to be used for cereals), and two rectangular buildings (probably former barns).

The discovered dwellings, on the site of a new housing development in Newquay, include large quantities of Bronze Age Trevisker ware pottery, Roman-period imported pottery, and worked stone tools from both periods.

According to the researchers, Bronze Age structures have been found at various sites across Cornwall over the past 30 years, however, the discovery of a cluster of roundhouses in such a small area is still a rare find.

Bronze Age Trevisker ware pottery was uncovered during the dig.

Sean Taylor, Senior Archaeologist at the Cornwall Archaeological Unit, said: “Although quite a few of these Bronze Age structures have been found at various sites around the county over the last 30 or so years starting with Trethellan at Newquay in 1987, it’s still rare to find so much in one small area.

“The Roman house is similar to buildings found at Trethurgy Round near St Austell in the 1970s and are of a type unique to Cornwall. The rectangular agricultural buildings on the other hand are fairly common throughout Roman Britain but this is the first time that they have been discovered in Cornwall.\“It’s starting to look like this part of Newquay, alongside the River Gannel, was a very important and densely populated area from the Neolithic (c 4000BC) onwards. The estuary undoubtedly formed an important link with the outside world throughout prehistory.”

The Cornwall Archaeological Unit completed their work at the end of March. The site will now be handed over to the developer, Treveth.

Many of the finds, which include large quantities of Bronze Age Trevisker ware pottery, Roman-period imported pottery, and worked stone tools from both periods, are expected to be housed in a local museum.

Deer stone discovered in Kyrgyzstan

A deer stone was found in the Tarmal-Sai settlement in the Kochkor district of the Naryn region in eastern Kyrgyzstan. Deer stones, also known as reindeer stones, are ancient megaliths with symbols carved into them.

Mongolia is rich with stone sculptures such as deer stones and complex heritage sites that belong to Bronze Age culture.

Deer stones name comes from their carved depictions of flying deer. Deer stones are a distinctive feature of the Saka era. A few deer stones have been discovered in Chui valley and Issyk-Kul Lake.

Deer stones will usually be found together with extraordinary monuments called khirgisuur, with slab burials or in some cases with petroglyphs forming a complex site.

Joldoshbek Butoshev, a resident of Tarmal-Sai, noticed a round stone with drawings while doing irrigation work and brought it home, thinking it might have historical significance.

Butoshev showed the discovery to a team of archaeologists visiting the region in 2022 under the direction of Oroz Soltobaev for research. The archaeologists determined that the stone was around 2000-2500 years old and suggested handing it over to a historical museum.

The stone is 1 meter long and weighs approximately 40-50 kilograms. On both sides of the stone, there are ritual sun signs, which are associated with the Saka and Wusun, who worshipped the sun.

According to the historian and founder of the historical museum in Kara-Suu village Bolot Boobek, the find is a deer stone that dates to between 2000 and 2500 years ago.

Deer stones are unique Bronze Age and Early Iron Age monuments found primarily in Mongolia and some Central Asian countries.

Deer stones represent the Bronze Age funeral practice, sacrificial ritual and ideology, and animal-style art that spread among ancient nomads.

Researchers believe these statues were dedicated to leaders and great warriors of a tribe.

Marble inlay floors were found in a Sunken Roman villa in Baia, the Las Vegas of the ancient world

Expansion of research activities in the Terme del Lacus area in the sunken Baia park, known as the ‘Las Vegas’ of the ancient world, has revealed new elements of ancient Roman luxury villas.

In the Gulf of Naples, a few kilometers from Pompeii, Baia was a vacation city for the capital’s rich and powerful during the Roman era, drawn to its natural volcanic vents and medicinal hot springs.

Some of the most important names in Roman history such as Caesar, Cicero, Mark Antony, Brutus, and Nero had villas in Baia.

The luxurious town was abandoned in the 8th century after being raided by a Muslim army, and in the 16th century, the underlying volcanic magma chamber emptied, a process known as bradyseism.

The land dropped about 20 feet below sea level, drowning more than half of Baia beneath shallow bay waters.

A section more than 260 feet long with visible remains, including a stone colonnade with collapsed columns made of fine imported Portasanta marble from Chios in Greece, was discovered during an exploration of the Baths of Lacus, a private thermal bath built inside a domus.

A large section of opus sectile (marble inlay) flooring was also discovered.

A large piece of marble opus sectile flooring has also been identified, still rendered in Portasanta in chromatic alternation with white or gray marble slabs. This currently appears as the most indicative dating element, being the typology and implementation referable to the Late Antiquity age.

The Lacus Baths site, which opened in 2020, allows scuba divers and snorkelers to explore the bath’s exceptional mosaic floors made of white, pink, red, green, grey, and black tiles.

It was a spa complex, most likely of a private residence, overlooking Baia’s ancient port, the Lacus Baianus.

In addition to the perimeters of various rooms and the thermal baths, three apses walls, which once supported large windows overlooking the Lacus Baianus, can be seen.

Archaeologists discovered an enigmatic complex of rooms, interiors of which covered with figural scenes unique to Christian art

Archaeologists of the Polish Center of Mediterranean Archaeology at the University of Warsaw discovered an enigmatic complex of rooms made of sun-dried brick, the interiors of which were covered with figural scenes unique to Christian art.

The discovery was made at the Old Dongola medieval monastery on the banks of the Nile, more than 500 km north of Khartoum.

Old Dongola (Tungul in Old Nubian) was the capital of Makuria, one of the most prominent medieval African states. It had converted to Christianity by the end of the sixth century, but Egypt was conquered by Islamic armies in the seventh century.

An Arab army invaded in 651 but was repulsed, and the Baqt Treaty was signed, establishing relative peace between the two sides that lasted until the 13th century.

The discovery was made during the exploration of houses dating from the Funj period (16th-19th century CE). Within the main monastic complex, the Polish mission unearthed now a second, well-preserved church with vivid mural paintings and inscriptions in Greek and Old Nubian.

Surprisingly, beneath the floor of one of the houses was an opening leading to a small chamber with walls decorated with unique representations.

The paintings inside depicted the Mother of God, Christ, and a scene with a Nubian king, Christ, and Archangel Michael. This was not, however, a typical depiction of a Nubian ruler under the protection of saints or archangels.

The king bows and kisses the hand of Christ, who is seated in the clouds. The ruler is aided by Archangel Michael, whose spread wings protect both the king and Christ. Such a scene finds no parallels in Nubian painting.

The representation’s dynamism and intimacy contrast with the hieratic nature of the figures depicted on the side walls. Similarly, the figure of the Virgin Mary on the north wall of the chamber does not fit into the standard repertoire of Mary depictions in Nubian art.

The Mother of God is dressed in dark robes and strikes a dignified pose. She has a cross and a book in her hands. On the opposite wall, Christ is depicted. His right hand is shown in a blessing gesture, and his left hand is holding a book, which is only partially preserved.

Dr. Agata Deptua of PCMA UW is currently studying the inscriptions that accompany the paintings. A preliminary reading of the Greek inscriptions revealed that they were texts from the Liturgy of the Presanctified Gifts.

The main scene is accompanied by an inscription in Old Nubian that is extremely difficult to decipher. The researchers learned from a preliminary reading by Dr. Vincent van Gerven Oei that it contains several references to a king named David as well as a prayer to God for the protection of the city.

The city mentioned in the inscription is most likely Dongola, and the royal figure depicted in the scene is most likely King David. David was one of Christian Makuria’s last rulers, and his reign signaled the beginning of the kingdom’s demise. For unknown reasons, King David attacked Egypt, which retaliated by invading Nubia, resulting in Dongola being sacked for the first time in its history.

Researchers think that the painting may have been made while the Mamluk army was approaching or the city was under siege.

The complex of rooms where the paintings were discovered, however, is what stumps people the most. The actual spaces, which are made of dried brick and covered in vaults and domes, are quite small. Although the painted room that depicts King David is seven meters above the medieval ground level, it looks like a crypt.

The structure is next to a sacred structure known as the Great Church of Jesus, which was likely Dongola’s cathedral and the most significant church in the Makurian kingdom.

According to Arab sources, the Great Church of Jesus instigated King David’s attack on Egypt and the capture of the ports of Aidhab and Aswan.

These and other inquiries about the enigmatic structure may be answered by further excavations. However, safeguarding the distinctive wall paintings was the main goal for this season. Following the discovery, conservators got to work under the supervision of Magdalena Skaryska, MA.

The Polish Centre of Mediterranean Archaeology, the University of Warsaw, and the Department of Conservation and Restoration of Works of Art of the Academy of Fine Arts in Warsaw collaborated to operate the conservation team.

“After the destruction of the Jerusalem Temple and the exodus of the Jewish population, late Roman Jerusalem—renamed Aelia Capitolina—had a mixed population. During this period, some young girls were buried and adorned with fine gold jewelry.

The jewelrys was discovered in a lead coffin on Mount Scopus during excavations led by late archaeologist Yael Adler of the Israel Department of Antiquities.

The find included gold earrings, a hairpin, a gold pendant, gold beads, carnelian beads, and a glass bead, according to the IAA.

The jewels were discovered in 1971, in an excavation carried out by Yael Adler (deceased) of the Israel Department of Antiquities but the finds were not published.

The jewels were recently located as part of the Israel Antiquities Authority’s “Publication of Past Excavations Project,” which aims to publish previously incomplete excavation reports.

Impressive gold jewelry discovered in previous excavations in Jerusalem burial caves will be on display for the first time to the public at the 48th Archaeological Congress, organized by the Israel Antiquities Authority, the Israel Exploration Society, and the Israel Archaeological Association.

The congress will take place at the Jay and Jeanie Schottenstein National Campus for the Archaeology of Israel, now inaugurated in Jerusalem.

“The location of the original reports that gathered dust over the years in the Israel Antiquities Authority archives, and physically tracing the whereabouts of the items themselves, has shed light on long-forgotten treasures,” says Dr. Ayelet Dayan, Head of the Archaeological Research Department, who heads this project. “The beautiful jewelry that we researched is an example of such treasures.”

Researchers from the Israel Antiquities Authority, Dr. Ayelet Dayan, Dr. Ayelet Gruber, and Dr. Yuval Baruch, believe that the priceless objects bearing the symbols of Luna, the Roman moon goddess, accompanied the girls during their lifetimes and were buried with them after they passed away to continue to protect them in the afterlife.

Their investigation revealed that Prof. Vassilios Tzaferis had found two pairs of identical gold earrings in a previous excavation on the Mount of Olives for the Department of Antiquities in 1975.

The finds, according to researchers, are from a time after Jerusalem had almost entirely been destroyed following the siege of 70 CE.

The pagan Roman deities Jupiter and others received special honors in Hadrian’s new city. At that time, Jews were forbidden from entering Jerusalem under penalty of death because the city was occupied by Roman legionaries.

“It seems that the girl was buried with an expensive set of gold jewelry that included earrings, a chain with a lunula pendant (named after the goddess Luna), and a hairpin,” say the researchers.

“These items of jewelry are known in the Roman world, and are characteristic of young girl burials, possibly providing evidence of the people who were buried at these sites,” the researchers said.

“Late Roman Jerusalem—renamed Aelia Capitolina—had a mixed population that reached the city after the destruction of the Jerusalem Temple and the evacuation of the Jewish population.

People from different parts of the Roman Empire settled in the city, bringing with them a different set of values, beliefs, and rituals. The pagan cult of the city’s new population was rich and varied, including gods and goddesses, among them the cult of the moon goddess Luna.”

According to researchers, gold jewelry was used as an amulet against the evil eye by young pagan girls nearly 1,800 years ago. The jewelry was buried with the girls to continue protecting them in the afterlife.

“The interring of the jewelry together with the young girl is touching,” said IAA Director Eli Escusido. “One can imagine that their parents or relatives parted from the girl, either adorned with the jewelry or possibly lying by her side and thinking of the protection that the jewelry provided in the world to come.

This is a very human situation, and all can identify with the need to protect one’s offspring, whatever the culture or the period.”

Simon Fraser University researchers are learning more about ancient graffiti—and their intriguing comparisons to modern graffiti—as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.

Working with the University of Ottawa, the researchers published their early findings in Egyptian Archaeology and have returned to Philae to advance the project.

“It’s fascinating because there are similarities with today’s graffiti,” says SFU geography professor Nick Hedley, co-investigator of the Social Sciences and Humanities Research Council (SSHRC)-funded project.

“The iconic architecture of ancient Egypt was built by those in positions of power and wealth, but the graffiti records the voices and activities of everybody else. The building acts like a giant sponge or notepad for generations of people from different cultures for over 2,000 years.”

As an expert in spatial reality capture, Hedley leads the team’s innovative visualization efforts, documenting the graffiti, their architectural context, and the spaces they are found in using advanced methods like photogrammetry, raking light, and laser scanning. “I’m recording reality in three-dimensions — the dimensionality in which it exists,” he explains.

With hundreds if not thousands of graffiti, some carved less than a millimeter deep on the temple’s columns, walls, and roof, precision is essential.

Typically, the graffiti would be recorded through a series of photographs — a step above hand-drawn documents — allowing researchers to take pieces of the site away and continue working.

Sabrina Higgins, an SFU archaeologist and project co-investigator, says photographs and two-dimensional plans do not allow the field site to be viewed as a dynamic, multi-layered, and evolving space.

“The techniques we are applying to the project will completely change how the graffiti, and the temple, can be studied,” she says.

Hedley is moving beyond basic two-dimensional imaging to create a cutting-edge three-dimensional recording of the temple’s entire surface.

This will allow the interior and exterior of the temple, and the graffiti, to be viewed and studied at otherwise impossible viewpoints, from virtually anywhere— without compromising detail.

This three-dimensional visualization will also enable researchers to study the relationship between a figural graffito, any graffiti that surrounds it, and its location in relation to the structure of temple architecture.

While this is transformative for viewing and studying the temple and its inscriptions, Hedley points to the big-picture potential of applying spatial reality capture technology to the field of archaeology, and beyond.

“Though my primary role in this project is to help build the definitive set of digital wall plans for the Mammisi at Philae, I’m also demonstrating how emerging spatial reality capture methods can fundamentally change how we gather and produce data and transform our ability to interpret and analyze these spaces. This is a space to watch!” says Hedley.

Drug Use Detected in Hair Found in Mediterranean Island Cave

Drug Use Detected in Hair Found in Mediterranean Island Cave

Drug Use Detected in Hair Found in Mediterranean Island Cave
Hair strands found among a stash of objects in this cave on the island of Menorca have provided Europe’s oldest direct evidence of psychoactive drug use, dating to about 3,000 years ago.

Human hair recovered in a Mediterranean island cave has yielded Europe’s oldest direct evidence of people taking hallucinogenic drugs, researchers say.

By around 3,000 years ago, visitors at Es Càrritx cave on Menorca — perhaps shamans who performed spiritual and healing rituals — consumed plants containing mind-altering and vision-inducing substances, say archaeologist Elisa Guerra-Doce of the University of Valladolid in Spain and colleagues.

Signs of human activity at the cave, including more than 200 human graves arrayed in a chamber at the entrance, were previously dated to between around 3,600 and 2,800 years ago.

Researchers had also found a hoard of objects in a small pit within an inner cave chamber, including six wooden containers, each containing locks of human hair.

Chemical analyses of one container’s locks, possibly from more than one person, detected three psychoactive plant substances that had been ingested and absorbed into the hair over nearly a year, the scientists report on April 6 in Scientific Reports.

A chemical analysis of human hairs, shown here entangled with bits of animal bones after removal from a wooden container found in a Mediterranean island cave, revealed the presence of mind-bending plant substances.

Two substances, atropine, and scopolamine from nightshade plants, induce disorientation, hallucinations, and altered physical sensations. Another, ephedrine, boosts energy and alertness.

Shamans would have known how to handle and consume these potentially toxic plants safely, the investigators say.

Individuals intent on preserving ancient traditions hid hair and other ritually significant objects at Es Càrritx as Menorca’s growing population spurred social changes between 3,000 and 2,800 years ago, the researchers speculate.

Burial rituals included dyeing strands of hair on corpses a reddish color and later cutting off some locks to be put in containers left near graves.

Other hair analyses have found that Inca kids slated for sacrifice more than 500 years ago ingested hallucinogenic drinks and coca leaves and alcohol (SN: 5/13/22; SN: 7/29/13).  And a 2005 study found chemical signs of coca-leaf chewing in the hair of two human mummies from Chile dating to around 3,000 years ago. Indirect evidence of drug use in various parts of the world, such as artistic depictions, go back further.
