• What was inside these pottery vessels 3,000 years ago?

In Peninsular Malaysia, researchers have found something unexpected preserved in prehistoric pottery: traces of milk.

A new study analysed 15 pottery fragments from three archaeological cave sites—Gua Cha, Gua Kajang and Gua Harimau—using techniques that can identify microscopic traces of foods absorbed into ceramics.

Among the substances detected were caseins and β-lactoglobulin, proteins found in milk. Their presence provides the earliest direct evidence yet reported for dairy processing in equatorial Mainland Southeast Asia, dating to around 3,000 years ago.

Archaeologists have long struggled to establish when farming and animal domestication became part of life in prehistoric Peninsular Malaysia. Unlike sites further north in Southeast Asia, clear evidence of early livestock management and cultivation has been difficult to find here, partly because animal bones and plant remains are often poorly preserved.

The milk proteins suggest that Neolithic communities were processing dairy products thousands of years ago. This does not necessarily mean they were raising dairy animals locally but it provides an important new piece of evidence for understanding food production and consumption in the region.

The researchers also identified traces of plant and animal foods, suggesting that these vessels were used for a variety of food-processing activities.

  • One river in northern Vietnam has yielded a remarkable record of more than 2,000 years of boatbuilding.

From the bed of the Kinh Thầy River at Cầu Bình, researchers documented 23 boat remains, including eight virtually complete logboat hulls and fragments of bows, sterns and planks. Radiocarbon dates place most of them between roughly 700 BCE and 1500 CE. 

Many hulls showed signs of sophisticated work beyond simply hollowing out a tree trunk. The hulls could be widened during manufacture, while wooden thwarts or bulkheads helped maintain their expanded shape. Some boats also carried additional boards along their upper edges, attached through holes with fibre lashings.

Around 2,000 years ago, during the late Đông Sơn and Han periods, several examples reveal another solution: mortise-and-tenon joints locked with wooden dowels. One boat even combined these joints with lashing holes. In later centuries, other Cầu Bình boats were built without this particular system.

This shows that over 2,200 years, boatbuilders used, combined and abandoned different solutions while continuing a long tradition of wooden river craft in the northern Red River Delta.

  • A 4.38-metre-long wooden rudder from the west coast of Sumatra is providing a rare glimpse of Southeast Asian seafaring around 1,300 years ago.

The rudder was recovered at the Bongal Site in Central Tapanuli, North Sumatra. Today the site lies inland, but geomorphological research suggests that in the 7th–8th centuries CE it was part of a shallow bay or estuarine environment.

The quarter rudder was carved from a single log and measures 4.38 metres long. Radiocarbon dating of the wood produced a calibrated date of 656–687 CE, making it the earliest securely dated rudder currently known from Southeast Asia.

Researchers also documented hull planks with raised wooden lugs, dowels and surviving palm-fibre ropes. These suggest that parts of these boats were pegged and tied together—a construction method archaeologists call the Southeast Asian lashed-lug tradition. Differences between the surviving planks even suggest that several vessels may have been present. 

Bongal also produced ceramics, glass, beads and coins pointing to connections with much wider exchange networks. The researchers do not argue that the Bongal boats themselves were making long-distance voyages across the Indian Ocean, but propose that locally constructed vessels formed part of a regional maritime network, moving through rivers and along Sumatra’s coast and connecting communities there to broader systems of exchange.

  • People in Sulawesi may have been habitually using a neuroactive plant as far back as 25,000–16,000 years ago.

A new study in Science Advances examines two preagricultural foragers from South Sulawesi, Indonesia, separated by thousands of years but sharing an unusual dental pattern: deep, rounded, circumferential wear that does not match ordinary chewing. The researchers argue that the wear formed through repeatedly holding, sucking or gently gnawing a small, hard object in different parts of the mouth. 

Using LC-MS, the team detected arecoline—a characteristic alkaloid of areca, or “betel”, nut—in dental samples from both individuals. One came from Leang Bulu Bettue and dates to 25–16 ka; the other, from Leang Cappalombo 1, is associated with deposits dating to around 7.6–6.3 ka. 

This was probably not betel chewing in the form familiar today. Modern betel quid typically combines processed areca nut with slaked lime and other ingredients. To test whether a simpler practice was plausible, the researchers soaked intact areca nuts and applied the resulting solutions to cells expressing human receptors. The experiments showed that intact nuts could release physiologically active arecoline without slaked lime. Combined with the dental wear, chemical residues and experiments support the authors’ interpretation that these foragers habitually sucked whole areca nuts.

For now, the sample is just two individuals, and psuggestions that the nuts were used for stimulation, pain relief or medicinal purposes remain hypotheses. What the study does show is that habitual neuroactive plant use may reach far deeper into the hunter-gatherer past than the archaeological record had previously demonstrated.

  • Twenty-two small beads can preserve the traces of a much larger world of movement and exchange.

A new archaeometric study examines beads excavated in 2023 at Khok Phithak, within the ancient city of Khu Bua in Ratchaburi, central Thailand. Khu Bua was an important urban centre associated with the Dvaravatī cultural sphere, enclosed by earthen ramparts and moats and situated within the Mae Klong river system. 

The researchers analysed 21 glass beads and one chalcedony/agate bead, combining microscopic observations with VP-SEM-EDS, LA-ICP-MS and micro-Raman spectroscopy. Manufacturing traces—including axial colour streaks and elongated bubbles—indicate that most of the glass beads were made by drawing glass into tubes or canes before cutting them into individual beads. 

Their chemistry indicates that nineteen beads belong to the m-Na-Al-1 glass subgroup, consistent with glassmaking traditions documented in South Asia, particularly the wider technological sphere of southern India and Sri Lanka. Together with their manufacturing technique, the authors associate these beads with the large-scale Indo-Pacific beadmaking tradition. 

However, one blue bead, B014, is made from plant-ash soda–lime glass with a broad western Asian affinity—although the study cannot identify a specific production centre. Another remarkable bead, B007, appears to have been wound from recycled iron-smelting slag, suggesting an entirely different production history.

Rather than evidence for primary glassmaking at Khu Bua itself, the authors interpret the assemblage as reflecting an inland centre of consumption and possibly redistribution, connected through maritime and riverine networks to much wider systems of Indian Ocean exchange.

21 August 2007 (MindaNews) – Elson T. Elizaga of the Heritage Conservation Advocates writes his account of the events surrounding the destruction of the Huluga Open Site in Cagayan de Oro, Philippines, and HCA’s bone (pun intended) with the National Museum of the Philippines.

Trash
Elson T. Elizaga

One important lesson I got from a news reporting class in Silliman University came from Dr. Crispin Maslog. He said that if you want to study a man, you take the contents of his wastebasket.

This advice is popular in other sciences, such as forensics, zoology, and archaeology. Put “midden important in archaeology” in google.com and you’ll find numerous references. Even if you insert “not” in the phrase, the result will be the same. One website is socialstudiesforkids.com. It says, “It might sound a little silly, but archaeologists can find out a lot about people by looking through their trash.” In 2006, trash middens in Alaska have changed a popular belief about Inupiat Eskimos.

Trash is encyclopedia.

On August 5, 2003, an archaeologist couldn’t contain her excitement when she found shells, animal bones, and earthenware sherds at the bottom of Obsidian Hill in Huluga. “Oh, we’ve found a midden, a kitchen midden!” Dr. Erlinda Burton exclaimed. Her companions were the wife and daughter of Atty. Maning Ravanera and myself.


A midden is “a mound or deposit containing shells, animal bones, and other refuse that indicates the site of a human settlement.” It’s garbage, in layman’s terms.

From the opposite side of the hill came archaeologists Leee Anthony Neri and Clyde Jagoon. They were examining the damage on the Huluga Open Site because of the road project of former mayor Vicente Y. Emano. Neri saw me holding a piece of bone and quickly but quietly extended a plastic bag in front of me. I was surprised. I hesitated, but since he was from the National Museum, I gave the piece to him. It looked like deer antler.

That was a beautiful day.

Two things Burton did immediately: She wrote to the National Museum, asking for a permit to dig at the midden site. She explained that her archaeology students would help. So, the project would be at NO COST to the government.

Then she requested the lot owner Wilson Cabaluna to protect the same area.

Strangely, however, the National Museum didn’t reply for weeks, despite government service rule that letters should be responded in 15 days. (A letter would reach Burton three months later.) And Cabaluna refused to cooperate, digging a pit in the midden instead. Alarmed, I sent pictures of the midden and found fossils to National Museum lawyer Trixie Angeles. No response.

In October 2003, Burton presented Huluga at the 4th annual conference of the Kapisanan ng mga Arkeologists ng Pilipinas (KAPI). She showed pictures of the midden and found contents. No big deal. No questions asked. Burton also suggested that the centralized National Museum should assign deputies in the provinces, but director Cora Alvina said the National Museum wasn’t mandated to do this. (Ma’am, a law can revise it.)

In November 2003, Burton proceeded with her planned excavation without a National Museum permit. She and her students, however, dug only in the lot of Danilo Bacarro, after getting his approval. Meanwhile, to Burton’s dismay, Cabaluna continued digging nearby and she had no authority to stop him. Burton’s team found only earthenware sherds in Bacarro’s lot.

Fast forward.

Enter the Archaeological Studies Program (ASP) in November 2004, hired by Emano to determine, among other objectives, if Huluga was a settlement site. They dug on top of the heavily eroded Obsidian Hill.

Two weeks later, they held a press conference, where they announced that the Huluga Open Site — which includes the hill — is a temporary campsite, not a site where people had continuously lived for a long time. They didn’t mention the midden. (The midden would be identified later in the ASP report as simply one of two “Treasure Hunter Pits”.)

Months later, ASP published a report of the excavations. The report states NO midden in Huluga. ASP also ignored the fossils and artifacts found by the Heritage Conservation Advocates in 2003 — such as the whale harpoon, which has counterparts in Siquijor, Bohol, Cebu and Lomblen Island of Indonesia. Lomblen is 2000 KILOMETERS south of Huluga. The Huluga whale harpoon has a National Museum accession number.

ASP also didn’t discuss the Copper 8 Maravedis coin. The coin is minted between 1788 and 1808, more than a century after Spanish missionaries landed in Cagayan de Oro in 1622. Although found only in the surface, three children told me several other coins were retrieved from the same site.

Somebody must have been happy about these critical omissions of ASP. He must have been pleased also that ASP did not consult Burton nor made her part of the team — which is dumb, because snubbing a resident archaeologist invites suspicion that visiting archaeologist have a purpose other than science.

What happened to our esteemed scientists from the University of the Philippines?

I don’t know, but these are the facts. Neri was leader of the ASP team. Her mother worked in the City Hall under Emano. In 2003, he told me that a two-week excavation in Huluga would cost P80,000. Emano gave his ASP group P700,000 for the same duration. Cabaluna is a City Tourism Office employee.

In August 2007, a reporter of the Philippine Daily Inquirer found two pits in the midden, each about 20 feet deep. Her article elicited criticism from ASP because she quoted me as describing the ASP report “a mock report”.

Actually, my original phrase was worse: “not scientific”.

Today, ASP maintains that the Huluga Open Site is a campsite — even though it’s still an archaeological site anyway. And they still score Burton for excavating “without a permit”. Meanwhile, without help from the National Museum, the midden in Cabaluna’s lot has turned into a black hole.

Such finesse truly impresses. In contrast, Emano’s destruction was quite crude.

Leee, you’re in the government. Why don’t you stop whining and call for a Senate investigation? Call everyone involved — including Burton, her students, and myself. Don’t worry. We can handle that.
