• Can inscriptions help reconstruct how a kingdom expanded across a landscape?

King Citrasena (Chitrasen, later known as Mahendravarman) ruled Chenla in the late 6th to early 7th centuries, during a period when Chenla’s influence was extending across parts of what are now Cambodia, Laos and northeastern Thailand. His reign is known partly through inscriptions recording religious foundations, royal achievements and other acts of authority. 

Pailoplee and Khatshima map 21 inscriptions from at least 19 locations associated with Citrasena, and asked if people were moving between these places, which routes would they have taken? To explore this, they use Least Cost Path (LCP) modelling in a GIS. LCP calculates routes that minimise the “cost” of movement across terrain.

In archaeology, this can help identify plausible corridors shaped by features such as slopes, river valleys and mountain barriers. These models show how movement could have been structured by the landscape under the assumptions of the model.

Across several scenarios, the reconstructed paths repeatedly concentrate around major river systems—especially the Mun River—and particular passes through the Phnom Dong Rek (Dangrek) mountain range. The authors also compare the modelled network with archaeological sites attributed to Citrasena’s period, many of which fall along these reconstructed corridors.

Where river navigation would have been difficult (such as the Khone Phapheng Falls), the authors propose that Citrasena’s forces may instead have moved overland along riverbanks, using waterways as natural guides through the landscape.

The placement of several inscriptions near river confluences also suggests that these locations may have been important for controlling movement, communication and exchange, not simply access to water.

  • Sometimes the biggest archaeological questions depend on evidence we cannot see during excavation.

Microarchaeology investigates archaeological deposits at microscopic and microstratigraphic scales. In Southeast Asia, this can be especially valuable because monsoonal wetness, tropical weathering, intensive land use and complex depositional histories can affect how archaeological evidence survives. 

Researchers can examine the surrounding sediment for traces of past activity and later disturbance. Methods discussed in this new paper include sediment micromorphology, laboratory micro-excavation, high-resolution imaging, FTIR microscopy and SEM-EDS. Depending on the context, microscopic evidence can help identify burning, trampling, plant processing, sediment movement and environmental change. 

The importance of that context is illustrated by work in northern Laos. At Tam Ngu Hao 2, microstratigraphy was used alongside lithological observations and dating to establish the stratigraphic context of Denisovan fossil evidence. At Tam Pà Ling, it has shown potential for investigating environmental seasonality and possible patterns of early modern human presence. These methods help archaeologists understand what happened to a deposit before drawing conclusions from what it contains.
 
The paper also introduces the Australian Microarchaeology and Palaeosciences Facility (AusMAP) and argues for greater collaboration, training and locally based microarchaeological expertise across Southeast Asia.

  • This week on Southeast Asian Archaeology: claims, contexts and careful reading.⠀
⠀
With Malaysia’s National Day, Vietnam’s National Day, Timor-Leste’s Popular Consultation Day, and International Literacy Day all close together, I’m thinking about literacy not just as reading words, but reading evidence: museum labels, old spellings, dates, maps, artefacts, archives, and the occasional viral post with a raised eyebrow.⠀
⠀
The catalyst this week is the recent controversy over historical claims in Malaysia, alongside a timely RSIS piece on how historians, archaeologists, archivists, librarians and curators can help push back against disinformation. Not by attacking people, but by helping everyone ask better questions of the past.⠀
⠀
Also in this week’s issue: Penang’s historical Malay spellings, Cambodia’s new artefact database grant, Singapore’s revised History Gallery, UNESCO’s maritime museum project, new research on Sundadonty, Roti Island, Chenla inscriptions, ancient Myanmar, and more.⠀

  • How old are the rock paintings of Mainland Southeast Asia? 🎨🪨

A new study from Mangguan in Yunnan, southwestern China, provides another important piece of the puzzle.

Using uranium-thorium dating, researchers analysed tiny calcite deposits that had formed over the paintings. Because the calcite must be younger than the pigment underneath, the dates provide a minimum age for the art. One deposit covering a human figure shows that the painting was already there at least 4,220 years ago.

Mangguan is particularly interesting because it lies only about 15 km from the better-known Cangyuan rock art complex. The two have stylistic similarities and overlapping dates, suggesting they formed part of a broader regional rock art tradition, a comparison can be taken farther south.

The rock paintings at Pha Taem in Luang Prabang, Laos, have previously been compared with Cangyuan, raising intriguing questions about relationships between the rock art traditions of southwestern China and Mainland Southeast Asia.

Most rock art in Mainland Southeast Asia remains poorly dated, so dates like those from Mangguan give us increasingly useful chronological anchors for thinking about these connections.

  • Extraordinary claims about the past can be exciting. But how do we tell an exciting new hypothesis from pseudoarchaeology?

Recent controversy in Malaysia over claims that ancient Malays taught the Romans shipbuilding provides a useful case study. Rather than piling on the person behind the claims, I think there is a more useful question to ask: how would we actually test an idea like this?

Archaeology gives us some simple tools.

Do the dates work? What is the primary evidence? Does the evidence actually demonstrate the connection being claimed? Are there better explanations? And perhaps most importantly: what evidence would make us reject the hypothesis?

Ancient Southeast Asians really were sophisticated seafarers. Srivijaya really was one of Asia’s great maritime powers. Sungai Batu really does preserve remarkable evidence for early iron production.

None of those achievements needs embellishment to make Southeast Asian archaeology extraordinary.

Swipe through for five questions you can use the next time you encounter an astonishing claim about the ancient past.

🚩 Remember: possibility is not evidence, similarity does not necessarily mean transmission, and extraordinary claims still have to survive ordinary archaeological scrutiny.

Read more about the archaeology behind these claims in this week’s Southeast Asian Archaeology Newsletter.

  • A 4,000-year-old painted stone from Wetar Island may change how we understand the Austronesian story.⠀
⠀
Archaeologists excavating Huknaur 1 in Southeast Indonesia found a painted plaque with a red sun-ray motif linked to the Austronesian Painting Tradition — a wider visual tradition known from eastern Indonesia and nearby islands.⠀
⠀
What makes this find so important is that the plaque appears to be older than the first pottery at the site. That means a shared symbolic tradition may have been present before the full Neolithic package usually associated with Austronesian expansion. This discovery suggests that ideas, symbols, and identity may have travelled ahead of pottery.⠀
⠀
It is a reminder that the spread of people goes beyond tools, crops, or ceramics, and may also have been about belief, belonging, and a shared visual language carried across the sea.⠀
⠀
Swipe through to see why this small object has such big implications.⠀

  • Plaques, Ponds and Provenance⠀
⠀
This week’s newsletter begins with a 4,000-year-old painted plaque from Wetar Island — a small object with a big story.⠀
⠀
The plaque carries a red sun-like motif linked to the Austronesian Painting Tradition, and it appears before pottery at the site. That suggests visual symbols and shared ideas may have moved through maritime Southeast Asia before some of the usual archaeological markers we associate with Austronesian expansion.⠀

  • How do you make a 3-metre stone stand upright for centuries?

At Hintang in northern Laos, archaeologists are beginning to answer that question.

In 2025, a Lao-Australian team excavated Site 7A — the first excavation at a Hintang standing-stone site in around 90 years. Beneath the surface, they found that the stones had been set deeply into pits, with smaller rocks packed around their bases to stabilise them. Roughly one-third of each standing stone was buried underground.

One big question remains, though — how old are the Hintang stones?

Samples were collected for dating, but those results are still being analysed. So, for now, we understand a little more about how these monuments were built.

  • Angkor’s water system is famous for its scale: enormous reservoirs, long canals, and monumental engineering.⠀
⠀
New research by archaeologist Sarah Klassen highlights how Angkor’s agricultural system also depended on more than 1,000 local temple communities spread across the Greater Angkor Region. These communities helped organise labour, manage local water systems, and coordinate rice production - and suggests that Angkor’s success was built through a combination of top-down and bottom-up management.⠀
⠀
The state created the large hydraulic framework. Local communities adapted to it, expanded around it, and helped make the wider agricultural landscape function.⠀
⠀
Over time, however, this balance changed. Land and resources became increasingly concentrated, the system became more centralised, and some of the flexibility that had helped Angkor cope with earlier environmental stress may have been lost.⠀

The world is introduced to Homo luzonensis – a news roundup

Big archaeology news from last week that has made news around the world as the announcement of a new identified human species from the Philippines, dubbed Homo luzonensis. The paper was published in Nature and it describes new bones discovered from the same stratigraphic later as the Callao Man, which was previously described as a diminutive human that lived in the Philippines 67,000 years ago. With the discovery of additional bones from at least three other individual, the team from France, the Philippines and Australia have enough data to describe it as a new species.

The discovery puts Philippine archaeology in the spotlight, with last year’s discovery of a fossil rhino with butcher marks dating more than 700,000 years old (see here and here). More excavations are being planned in Cagayan, and this discovery, along with the previous discovery of Homo floresiensis will put a lot of focus on human evolution and Southeast Asia’s role in it.

Here’s the link to the Nature paper, links to news articles below:

A new species of Homo from the Late Pleistocene of the Philippines
Nature, 568, pp. 181–186 (2019)

A hominin third metatarsal discovered in 2007 in Callao Cave (Northern Luzon, the Philippines) and dated to 67 thousand years ago provided the earliest direct evidence of a human presence in the Philippines. Analysis of this foot bone suggested that it belonged to the genus Homo, but to which species was unclear. Here we report the discovery of twelve additional hominin elements that represent at least three individuals that were found in the same stratigraphic layer of Callao Cave as the previously discovered metatarsal. These specimens display a combination of primitive and derived morphological features that is different from the combination of features found in other species in the genus Homo (including Homo floresiensis and Homo sapiens) and warrants their attribution to a new species, which we name Homo luzonensis. The presence of another and previously unknown hominin species east of the Wallace Line during the Late Pleistocene epoch underscores the importance of island Southeast Asia in the evolution of the genus Homo.
