Identifying use-related residues from stone artefacts has become increasingly important in determining starchy plant exploitation over time and in different locales. Standard methods for processing residues samples are widely available but there is no clear consensus on suitable methods for attributing unknown starch grains to known plant taxa. We revisit the case study of a flaked stone artefact (K/76/S29B) recovered from Phase 1 (c. 10,000 ka) at Kuk Swamp in Papua New Guinea (PNG). Starch grains from taro ( Colocasia esculenta ) were identified in the residue extraction, but there were other grains that could not be attributed a plant origin at that time. The new analysis applied robust statistical methods, categorial attributes and expert input. In addition to C. esculenta , kudzu bean ( Pueraria montana var. lobata ) was identified, representing the earliest use of kudzu bean in the PNG highlands. Importantly, we also determined that starch grains from C. esculenta and Dioscorea esculenta are morphologically indistinguishable. We turned to other attributes of potential contributing plant taxa in determining distinguishing features: habit/growing requirements; the sedimentary context of the archaeological find; and environmental settings. Cultural use of both plants, artefacts and artefact technologies can be critical elements in confident identification outcomes, as exemplified here.

New Guinea has yielded some of the earliest evidence for a human presence in Sahul (Pleistocene Australia-New Guinea), with the north coast being one of the likely colonisation routes from Southeast Asia. Of the known pre-Last Glacial Maximum (≥30kya) archaeological sites from New Guinea, only a handful come from the Highlands. Navigable pathways linking the north coast to the central cordillera, specifically ‘grassland corridors’, may have facilitated settlement, yet little is known about human settlement of fringe montane valleys within these corridors. A survey and excavation program within the Simbai-Kaironk Valleys (2,000–1,600 m asl) on the northern montane fringe identified 51 sites across a 21 km corridor. Radiocarbon dating suggests a possible human presence from 31 ka, clear evidence for landscape use from 17 to 15 ka, and an increase in site density from the Mid-Holocene. Most sites were from open settings, with Holocene settlements positioned at elevations optimising access to montane forests, grasslands and lowland resources. We argue that the Simbai-Kaironk grassland corridor has facilitated access to the central Highland valleys since the Late Pleistocene. Shorter and more direct pathways, transecting the river valleys via prominent spurs rising above the lowlands – and their associated insect-borne diseases – are likely to have facilitated coastal-Highland movement throughout the Holocene.

New Guinea was host to some of the most complex maritime interaction networks in the tropics. We take a multi-proxy approach to investigate the foodways at the heart of the extensive Madang exchange network in the last millennium before the present: 1) invertebrate zooarchaeological analysis identifies the dependence on shellfish collecting from the coral reef and sandy floor littoral zone; 2) examination of vertebrate remains demonstrates the rearing and consumption of key domesticated animals (pigs and perhaps dogs), alongside reef fish, birds, and possibly snakes; 3) human dental calculus analysis distinguishes that marine plants, palm, betelnut, and probably banana were consumed; 4) pottery residue analysis suggests that a variety of starchy crops were being cooked in locally made ceramics. We use this information to develop interpretations about the nature of land-use, mobility, and exchange along New Guinea’s coastal fringe, as well as how foodways have transformed throughout the Late Holocene.

Shift in human settlement patterns and technologies in New Guinea highlands is linked with changing food production strategies.

Understanding the loss of the final few species of Australian megafauna is beset by a paucity of data on human arrival, well‐provenanced megafauna, human/megafauna population range and distribution (coexistence and interaction), and the range, scale and impact of environmental changes spanning the human–megafauna period. To overcome these shortcomings, the occurrence and decline of coprophilous fungal spores of Sporormiella in sediments have been used as a proxy for extinct megaherbivores. The Sporormiella evidence is presented as the key indicator of extinction timing and these reports are often from locations where there is no known archaeological record or megafauna remains. However, interpreting fungal spore occurrence is not straightforward, as demonstrated by studies investigating taphonomy, taxonomy and the types of animal dung where Sporormiella occurs. No detailed studies on these problems exist for Australia and no evidence supporting the use of Sporormiella as a valid proxy has been reported. Here we examine the occurrence of Sporormiella spores from Cuddie Springs in south‐eastern Australia. Despite a well‐preserved suite of megafauna fossils, Sporormiella occurrence is sporadic and frequencies are low. We conclude that using Sporormiella alone as an indicator for the presence of megafauna is premature for the Australian context.

Here we report the results of excavation and analyses of an open site on Pulau Ay, a small (ca. 4 km2) limestone island located in the Banda Islands, central Maluku, Indonesia. This report provides results of excavations at PA1 and other Pulau Ay sites conducted in 2007 and 2009. These sites reveal patterns of changes in marine resource exploitation, pottery, and use of domestic animals, particularly between initial occupation of the site at approximately 3500 b.p., and later phases commencing approximately 3000 b.p. Archaeobotanical analyses reported here provide insight into early Neolithic plant use, including early use of Myristica fragans (nutmeg) in a food context. The PA1 site adds to a growing data set about early Neolithic lifeways in Island Southeast Asia and provides a new view of cultural adaptations happening in the region during this critical period.

This article presents archaeological data critical to our understanding of the pre-colonial past along the northeast coast of New Guinea. Two archaeological sites from coastal and offshore Madang, Papua New Guinea, were excavated to establish the timing of colonization by Bel (Austronesian) speakers, and the subsequent emergence of their trade and exchange networks along the coast leading up to ethnographic accounts. These sites include Nunguri on Bilbil Island, formerly the center of the expansive Madang (Bilbil) pottery exchange network, and Tilu, Malmal village, a pottery consumption area along the coast. Both excavations suggest that initial occupation at these sites by the Bel-speaking groups occurred very recently in the last millennium before present (c. 550–650 cal BP), which is broadly in line with oral history and linguistic evidence. From the start, this occupation involved local red-slipped pottery production and distribution, the exchange of obsidian and sedimentary lithics, and the consumption of nearshore marine resources along with key domesticated animals. In-depth descriptions of these investigations and the archaeological material are presented here.
