An extensive body of engraved rock art on the Great Papuan Plateau is documented here for the first time, along with the first dates for occupation. Consisting largely of deeply abraded or pecked barred ovals and cupules, the rock art of this region does not fit comfortably into any regional models for rock art previously described. It does, however, exhibit some similarity to art in regions to the east and the west of the plateau. Subject to further archaeological testing, we present a number of exploratory hypotheses with which to explain the presence of the engravings; as part of the ethnographic and contemporary Kasua's cultural suite; as part of a relatively recent (late Holocene) migration of peoples from the Gulf to the plateau; or as part of an earlier movement of people from the west, possibly as part of the movement of people into the Sahul continent in the Late Pleistocene. We conclude that the Great Papuan Plateau is not a late and marginally occupied 'backwater' but rather part of a possible corridor of human movement across northern Sahul and a region that could allow us to better understand modern humans as they reached the Sahul continent.

This study explores the application of soil micromorphological and automated scanning electron microscopy mineralogical analysis to characterise lithological boundaries and site formation history from an archaeological cave site on Barrow Island, northwestern Australia. The high-resolution characterisation is used to document the changing depositional context within Boodie Cave from the earliest period of occupation around 50 ky BP through to when transgressing seas isolated the island around 7 ky BP. Comparisons are made between excavations at the front of the cave — where stratigraphic integrity is high and a thicker, more comprehensive early Holocene sequence is preserved, with excavations inside the cave — where stratigraphic integrity is lower but an older Pleistocene record is preserved. The combination of these depositional scenarios provides a complete stratigraphic sequence for Boodie Cave, with depositional contacts defined at macro-, meso- and microscale levels. These contacts include erosive surfaces and trampled (ground) surfaces, such as the upper interface of SU5 and SU4. Based on the mineralogical and textural variations (microfacies) preserved within each unit, the vertical mixing zone is estimated to be between 1 and 5 cm. This reworking has not affected the general sequence of sedimentological (including grain size and mineralogy) and macro-cultural changes, which record an increasingly marine-dominated assemblage as the coastline encroaches. The integration of microscopic observations with anthracological, archaeomalacological, zooarchaeological and lithic analyses provides a more dynamic and comprehensive dialogue for interpreting the formation history of Boodie Cave and likely other early occupation sites from northern Australia

Published ages of >50 ka for occupation at Madjedbebe (Malakunanja II) in Australia's north have kept the site prominent in discussions about the colonisation of Sahul. The site also contains one of the largest stone artefact assemblages in Sahul for this early period. However, the stone artefacts and other important archaeological components of the site have never been described in detail, leading to persistent doubts about its stratigraphic integrity. We report on our analysis of the stone artefacts and faunal and other materials recovered during the 1989 excavations, as well as the stratigraphy and depositional history recorded by the original excavators. We demonstrate that the technology and raw materials of the early assemblage are distinctive from those in the overlying layers. Silcrete and quartzite artefacts are common in the early assemblage, which also includes edge-ground axe fragments and ground haematite. The lower flaked stone assemblage is distinctive, comprising a mix of long convergent flakes, some radial flakes with faceted platforms, and many small thin silcrete flakes that we interpret as thinning flakes. Residue and use-wear analysis indicate occasional grinding of haematite and woodworking, as well as frequent abrading of platform edges on thinning flakes. We conclude that previous claims of extensive displacement of artefacts and post-depositional disturbance may have been overstated. The stone artefacts and stratigraphic details support previous claims for human occupation 50-60 ka and show that human occupation during this time differed from later periods. We discuss the implications of these new data for understanding the first human colonisation of Sahul.

A GPR survey was carried out in advance of archaeological excavations at Madjedbebe (formerly known as Malakunanja II), a sandstone rock shelter in western Arnhem Land (Australia) containing numerous Aboriginal burials. GPR revealed subsurface patterning

Located at the crossroads of two rather different ecological and cultural worlds (Mediterranean Spain and Portuguese Atlantic), the site of Vale Boi (Algarve, Portugal) is a crucial element in understanding the economic and social traits of the communities that inhabited Southwestern Iberia during the Last Glacial Maximum (LGM). Combining an open-air with a rockshelter component, Vale Boi presents a lengthy Solutrean record starting with a Proto-Solutrean phase followed by a set of occupations in the 25 to 20.3 ka cal BP time-span. The very rich and well preserved assemblages proved that the site was treated, throughout, as a seasonal residential camp and although a striking combination of exogenous cultural traits has been identified, regional adaptive idiosyncrasies are quite evident. This paper focuses on the results of the lithics, fauna, beads and portable art analysis from Vale Boi, and their impact on the comprehension of the LGM ecodynamics in Southwestern Iberia., Localizado en el marco de dos contextos diferentes desde el punto de vista ecológico y cultural (el Mediterráneo español y el Atlántico portugués), el yacimiento de Vale Boi (Algarve, Portugal) es un lugar fundamental para comprender la organización económica y social de las comunidades que habitaron el sudoeste de la Península Ibérica durante el Último Máximo Glacial (LGM). Situado en una zona en la que se combinan ocupaciones al aire libre y en abrigo, Vale Boi presenta un amplio registro solutrense que comienza con el Proto-Solutrense y a la que le siguen un amplio número de ocupaciones entre el 25 y el 20,3 ka BP. El importante y bien preservado conjunto demuestra que este asentamiento funcionó como un campamento residencia estacional. Aunque han sido identificados diversos caracteres culturales de origen exógeno, son también evidentes los elementos adaptativos idiosincráticos. El presente artículo se centra en los resultados de los análisis del utillaje lítico, la fauna, las cuentas ornamentales y los objetos de arte mueble de Vale Boi y su impacto en la comprensión ecodinámica del LGM en el sudoeste de la Península Ibérica.

En los 150 años de investigaciones sobre el Paleolítico portugués realizados hasta el momento, sólo se cuenta con un reducido número de yacimientos cronológicamente atribuidos al Gravetiense dentro del marco geográfico del sudoeste peninsular. En este contexto, el asentamiento de Vale Boi (Algarve, Portugal) ha revelado datos muy importantes para el conocimiento del Pleistoceno superior con ocupaciones humanas del Paleolítico medio y superior. En este trabajo presentamos la información obtenida sobre la tecnología, la subsistencia, la territorialidad o la identidad de las comunidades gravetienses en Vale Boi. El conjunto de datos disponibles parece revelar una gran integridad tecnológica, social y cultural. La adaptación ecológica a esta área muestra características singulares cuando son comparadas con los registros gravetienses en otros territorios de la península ibérica., espite of c. 150 years of Paleolithic research in Portugal, only a small number of archaeological sites in southwestern Peninsula are attributed to the Gravettian. Thus, the archaeological site of Vale Boi (Southern Portugal) provides important data on the Early Upper Paleolithic of Southwestern Iberian Peninsula. The Vale Boi chronostratigraphy sequence is composed of middle and upper Paleolithic - Mousterian, Gravettian, Proto-Solutrean, Solutrean and Magdalenian. In this paper, we present the technological and subsistence patterns for the Gravettian of Vale Boi. All these patterns reveal technological high technological investment as well as social and cultural adaptation by these communities. This ecological adaptation to a new territory shows different characteristics when compared to the general patterns seen from the Gravettian of other areas of Iberia.

The Upper Paleolithic site of Vale Boi in coastal, southwestern Portugal currently represents the earliest known case of grease-rendering in Eurasia, with initial occupation occurring during the early Gravettian at ~ 27,000 BP. Long-term exploitation of marine resources is indicated by marine shellfish remains, mainly in the form of limpets (Patella), recovered from all three cultural periods (Gravettian, Solutrean and Magdalenian). High-level exploitation of rabbits (Oryctolagus) began with initial use of the site and continued throughout the occupations, with a possible increase in intensity at the onset of the Solutrean. Grease-rendering of red deer (Cervus elaphus), horse (Equus caballus), European ass (Equus hydruntinus) and aurochs (Bos primigenius) bones was identified through multi-dimensional taphonomic and zooarchaeological analyses. Ungulate remains demonstrated extensive fragmentation and abundant evidence of impact features such as cone fractures, crushing, denting and cracking. The intensity of fragmentation and impact damage to red deer remains is significantly correlated with quantities of marrow and bone grease within these portions. Lack of density-mediated attrition of either the leporid remains or the cranial bone of red deer and horse, demonstrates that the loss of low-density, grease-rich post-cranial skeletal portions is due to human subsistence activities. Balanced body-part representation of ungulates indicates that density-mediated attrition of post-cranial elements is not related to differential transport of carcass portions. Comparison of element portion frequencies to food utility indices further demonstrates that humans were systematically harvesting marrow and bone grease throughout the Gravettian, Solutrean and Magdalenian culture periods. The co-occurrence of fire-cracked rock, stone anvils and hammerstones corroborates this suggestion. Although grease rendering at Vale Boi pre-dates other known sites in Eurasia by several thousand y
