Are osseous artefacts a window to perishable material culture? Implications of an unusually complex bone tool from the Late Pleistocene of East Timor

We report the discovery of an unusually complex and regionally unique bone artefact in a Late Pleistocene archaeological assemblage (c. 35xa0ka [thousands of years ago]) from the site of Matja Kuru 2 on the island of Timor, in Wallacea. The artefact is interpreted as the broken butt of a formerly hafted projectile point, and it preserves evidence of a complex hafting mechanism including insertion into a shaped or split shaft, a complex pattern of binding including lateral stabilization of the cordage within a bilateral series of notches, and the application of mastic at several stages in the hafting process. The artefact provides the earliest direct evidence for the use of this combination of hafting technologies in the wider region of Southeast Asia, Wallacea, Melanesia and Australasia, and is morphologically unparallelled in deposits of any age. By contrast, it bears a close morphological resemblance to certain bone artefacts from the Middle Stone Age of Africa and South Asia. Examination of ethnographic projectile technology from the region of Melanesia and Australasia shows that all of the technological elements observed in the Matja Kuru 2 artefact were in use historically in the region, including the unusual feature of bilateral notching to stabilize a hafted point. This artefact challenges the notion that complex bone-working and hafting technologies were a relatively late innovation in this part of the world. Moreover, its regional uniqueness encourages us to abandon the perception of bone artefacts as a discrete class of material culture, and to adopt a new interpretative framework in which they are treated as manifestations of a more general class of artefacts that more typically were produced on perishable raw materials including wood.

Human Palaeoecological Interactions and Owl Roosting at Tron Bon Lei, Alor Island, Eastern Indonesia

ABSTRACT We report on tetrapod (Reptilia, Amphibia, Mammalia, Aves) vertebrates recovered during excavations at Tron Bon Lei rockshelter on the south coast of Alor Island, eastern Indonesia. These include both archaeological specimens recovered from a 1 m² test pit dating from ∼21 kya cal BP to the late Holocene, and a modern eastern barn owl deposit recovered nearby. To discern between the depositional processes that accumulated the small numbers of micro- and macrovertebrate remains from the archaeological deposits, the taphonomic signature of the natural assemblage was quantified and compared to the archaeological record. The taphonomic data indicates that the tetrapod archaeofaunal remains are a combination of barn owl predation of microfauna and human predation of larger fauna. This approach provides new information on human-tetrapod interactions on Alor in Wallacea during the late Quaternary, including an apparent increase in cave site use and hunting intensity during the Pleistocene-Holocene transition, sea turtle butchery and probable transport, and extinctions of previously unknown giant to large rat species.

Birriwilk rockshelter: a mid- to late Holocene site in Manilikarr Country, southwest Arnhem Land, Northern Territory

Abstract Recent excavations at the Birriwilk rockshelter in Mikinj Valley, southwest Arnhem Land, have revealed evidence for mid- to late Holocene settlement, including a major period of site use in the last millennium. The site is important to the traditional owners, with a rich oral tradition associated with ‘Birriwilk’, an ancestor of the Urningangk tribe, who is depicted in rock art at the site. Oral traditions link Birriwilk with an adjacent lagoon, as well as a number of other rock art sites and features in the landscape, including the renowned Ubirr complex. The Birriwilk site and vicinity are significant places to the Nayinggul family, traditional owners for the Manilikarr estate. This post-fieldwork report summarises key archaeological findings at Birriwilk, using frequencies of stone artefacts and faunal remains as proxies of occupation from ca 5000 years ago. The most intense occupation occurred within the last 700 years, a period characterised by foraging and hunting in adjacent wetland habitats, changing technological emphasis to the manufacture of bifacial quartzite points, increased artefact discard rates and increased ochre grinding. The site has little archaeological evidence of use during the last 200 years, although oral histories indicate it was visited regularly until the mid-twentieth century. The rockshelter remains an important story site today.

The Walandawe tradition from Southeast Sulawesi and osseous artifact traditions in island Southeast Asia

This chapter describes a sample of points and other osseous artifacts recovered from Holocene contexts at three sites in Walandawe, Southeast Sulawesi, Indonesia. Microscopic observations of use traces and manufacturing techniques are presented as well as metrical observations and morphological classifications. The points show a suite of temporal trends apparently related to a shift from a predominant use as hafted projectile points to their growing use as penetrative tools. Trends include a higher incidence of wear and decline in tip damage, a decrease in bipoint production, an increased focus on unipoints, and a manufacturing shift from predominantly scraping cortical bone to frequently grinding suid incisors and long-bone shafts. Notwithstanding these changes, the Walandawe osseous artifacts constitute an identifiable tradition with systematic differences from other Island Southeast Asian assemblages located in southwest Sulawesi and especially Borneo, the Aru Islands, the northern Moluccas and the New Guinea Bird’s Head.

The chronology and environmental context of a cave deposit and associated faunal assemblage including megafauna teeth near Wee Jasper, southeastern Australia

A limestone cave on the lower slopes of the southeastern Australian high country reveals a deep, stratified deposit dated from ca. 14,000 to 2000 cal. BP and rich in predominantly non-cultural faunal remains. Located in a sensitive ecological area between the Australian Alps and the Southern Tablelands, the site provides a valuable chronological archive for the interpretation of local environmental change using the faunal record as a proxy, in particular native rodents and other small mammals. Inferred palaeoenvironmental trends include the cessation of periglacial conditions in the surrounding ranges during the Terminal Pleistocene; a shift to warmer conditions and the establishment of forest and wetland habitats from around 13,500 to 10,000 cal. BP, with a significant decline in cold-adapted species at ca. 11,500 cal. BP and a period of significant taxon fluctuation and extinctions corresponding to a possible peak in warm and moist conditions (a ‘Holocene Optimum’), beginning around 8000 cal. BP and lasting perhaps 1500 to 2000 years. Complications to the relatively steady and continuous chronostratigraphy, formed from an AMS radiocarbon sequence from sedimentary charcoal, arose from the presence of several teeth of extinct sthenurine megafauna. These were resolved with direct U-series analysis to establish their much greater antiquity and comparison of the sthenurine teeth with teeth of extant macropodids from the same deposit through fluoride absorption analysis, which also identified the megafauna teeth as anomalous to the sequence. The site provides an important case study for the interpretation of megafauna remains in stratified sedimentary deposits, especially for sites that appear to contain evidence for the co-occurrence of megafauna and humans in primary contexts.
