The distribution of the river shark Glyphis in northern Australia is extended with new records of occurrence in the Gulf of Carpentaria and a reassessment of historical survey data from Cape York Peninsula. Nine new specimens of Glyphis sp. A were collected in 2005 from the Weipa region on the Queensland coast of the Gulf of Carpentaria. A re-examination of archival records from 1978–86 marine and estuarine fish surveys in the Gulf of Carpentaria and along the northern Queensland East Coast allowed a further nineteen Glyphis specimens to be identified. Combined this gives twenty-eight new records of Glyphis specimens from the coasts of Cape York Peninsula, Queensland. Common habitat characteristics for all captures were turbid, shallow, fast running tidal water in the upper reaches of coastal rivers. The substrate was generally muddy and the rivers lined with mangrove. In all surveys the representation of Glyphis was low, being less than 1% of the total shark captures historically and 0.002 sharks 50 m net hour -1 in Weipa 2005. The size range captured was 1000–1800 mm total length historically and 705 –1200 mm total length from Weipa 2005, with none recorded as sexually mature. Diagnostic characteristics of the Weipa specimens, identified as Glyphis sp. A, were: lower jaw teeth protruding and “spear-like”; second dorsal fin greater than half the height of the first dorsal fin; the snout relatively short and fleshy in the lateral view; pectoral fin ventral surface black in colouration; the precaudal vertebral count between 118 and 123; and the total vertebral count between 204 and 209.

Shell mounds located on the coastal and estuarine fringes are the best-known archaeological feature in the Weipa region, northwestern Cape York Peninsula, Australia. Other archaeological deposits have received less attention, with stone artefacts thought to be all but absent reflecting the lack of raw material suitable for flaking in the region. Cultural heritage surveys on the bauxite plateau in the Weipa region undertaken since 2003 have changed this view. Here we report on stone artefacts manufactured from quartz, quartzite, silcrete, and mudstone. Surprisingly, flakes and cores in assemblages from across the surveyed region retain a relatively large proportion of cortex, indicating limited lithic reduction despite the lack of local raw material. Comparisons made with assemblage characteristics from other regions in Australia indicate that this lack of core reduction may reflect use of the Albatross Bay landscape by people who were confident of being able to access the lithic sources outside the region to replenish their tool kits.

<p>The Weipa shell mounds have a long history of archaeological research that has made a significant contribution to our understanding of the emergence of late Holocene coastal economies in northern Australia. However, much of this work has focused on broad comparisons of mounds between multiple locations rather than detailed studies of multiple mounds from single locations. This level of analysis is required to understand the record of both human occupation and environmental change and how these have given rise to the form of archaeological record visible in the present. In this paper we describe the results of a recent pilot study of four <em>Anadara granosa</em>-dominated shell mounds at Wathayn Outstation near Weipa in far north Queensland. We adopt a formational approach that investigates variability in shape, size, orientation, stratigraphy, shell fragmentation and diversity and mound chronology, as well as dating of the surfaces upon which the mounds have been constructed. Results indicate multiple periods of shell accumulation in each mound, separated by hiatuses. The mounds are the end product of a complex mix of processes that include how often and how intensively mounds were used and reused, together with the nature of the shell populations that people exploited and the post-depositional environmental changes that have occurred over the centuries the mounds have existed.</p>

This paper reports on a glass artefact found on an earth mound at Diingwulung in Wathayn Country, near Weipa, far north Queensland. Despite intense research efforts and cultural heritage management surveys over many years, and the fact that they have been reported commonly within the ethnographic literature, such artefacts have been found rarely outside of Aboriginal mission contexts. As well as describing the artefact, its location and the frontier contact complex of the area, this paper includes the background of knapped glass artefacts in Australia, archaeological and ethnographic descriptions of Indigenous glass use in far north Queensland and the methodology of glass artefact analysis. Although it is only a single artefact, we argue that this glass piece has much to reveal not only regarding its chronology, use, and the function of the site where it was found, but also about culture contact, persistence of traditional technology, connections to Country and the continuity and extent of post-contact Indigenous occupation of the area.

Bandy-bandies (genus Vermicella) are small (50–100cm) black and white burrowing elapids with a highly specialised diet of blindsnakes (Typhlopidae). There are currently 5 recognized species in the genus, all located in Australia, with Vermicella annulata the most encountered species with the largest distribution. Morphological and mitochondrial analyses of specimens collected from the Weipa area, Cape York, Queensland reveal the existence of a new species, which we describe as Vermicella parscauda sp. nov. Mitochondrial DNA analysis (16S and ND4) and external morphological characteristics indicate that the closest relatives of the new species are not V. annulata, which also occurs on Cape York, but rather species from Western Australia and the Northern Territory (V. intermedia and V. multifasciata) which, like V. parscauda, occupy monsoon habitats. Internasal scales are present in V. parscauda sp. nov., similar to V. annulata, but V. intermedia and V. multifasciata do not have nasal scales. V. parscauda sp. nov. has 55–94 black dorsal bands and mottled or black ventral scales terminating approximately 2/3rds of the body into formed black rings, suggesting that hyper-banding is a characteristic of the tropical monsoon snakes (V. intermedia, V. multifasciata and V. parscauda). The confined locality, potential habitat disruption due to mining activities, and scarcity of specimens indicates an urgent conservation concern for this species.

Bauxite ore in the deposit at Weipa, Queensland, Australia occurs as pisoliths which are small, approximately spherical, pebbles with diameters in the range 0.5 to 2 cm. The distribution of various mineral species within the pisoliths has been determined by the use of reflectance infrared microspectroscopy of a large suite of pisoliths obtained from different parts of the Weipa orebody. The method allows the significant minerals of the bauxite to be analyzed including gibbsite (aluminium trihydroxide), boehmite (aluminium oxyhydroxide), quartz, and the clay, kaolinite. These minerals are readily distinguished by their IR spectrum. The iron minerals, present in small amounts, could not be detected. Specular reflectance spectra of sectioned pisoliths were measured, and the spectrum was utilized directly without the application of the Kramers–Kronig transformation. Polished pisolith sections were also mapped at a spatial resolution of 100 μm with the use of a computer-controlled microscope stage, and the mineral composition at any point was estimated by measuring relevant areas of the spectrum. Semi-quantitative results were obtained by relating the reflectance spectra for a particular pisolith thin section to the transmittance spectra for the same points. The transmittance spectra of the pisoliths were correlated with spectra of pure standards by application of a multicomponent Q-matrix approach. Principal component analysis of the mineral distribution data allowed the suite of pisoliths to be subdivided into groups with similar mineralization.

Concern over the long-term sustainability of post-mining ecosystems at Weipa (North Queensland, Australia) led to investigations of soil organic matter dynamics, a key process linking soil and vegetation development in maintenance-free systems. Paper I of this series examined the short-term effects of rehabilitation operations on soil organic matter. Here, we assess the medium-term development of post-rehabilitation soil organic matter quantity and quality using mine soil chronosequences of up to 22 years post-rehabilitation at Weipa. Soils had been respread either immediately after stripping or after stripped soil had been stockpiled for several years. Sites surveyed were revegetated with native tree and shrub species, forestry (Khaya senegalensis), or pasture (Brachiaria decumbens/Stylosanthes spp.). Three areas of undisturbed native forest were included for comparison. Compared with the undisturbed forest, rehabilitated soils were shallower and more compacted, contained more gravel, and, as a result of topsoil–subsoil mixing, stored less organic matter in the surface soil. Rehabilitated sites respread with stockpiled soil were more compacted and lower in all quantitative and qualitative measures of organic matter than freshly replaced soils. With time, organic matter accumulated in the surface soil under all vegetation types at rates of up to 1.25 t C/ha.year, but new equilibrium levels were yet to be reached. Accumulated organic matter was mostly associated with clay and silt-sized particles, indicating effective cycling of litter to humus. Nitrogen mineralisation capacity increased with time under all vegetation types. The incidence of fire led to increased total and light-fraction organic C, but this was probably as charcoal C. Sites where volunteer grass biomass was reduced pre-planting by late-season stripping or disc-ploughing accumulated less organic C. To optimise post-mining soil organic matter development, we recommend that soil stockpiling be avoided, that more volunteer grasses be retained to ensure continuity of organic inputs, and that attention be focussed on minimising soil compaction and gravel incorporation—both permanent limitations to plant growth.

The aim of this research is to determine to what extent properties of the regolith may be inferred using only features easily measured from the surface. To address this research question, a set of regolith properties from Weipa, Queensland, Australia, are analysed. The set contains five variables, oxides of Aluminium, Iron, Silica and Titanium, as well as Depth to Ironstone. This last represents the depth of the layer from which the oxides are sampled.¶ The research question is addressed in two ways. First, locations where the properties are related to modern surface hydrology are assessed using spatially explicit analyses. This is done by comparing the results of spatial association statistics using geometric and watershed-based spatial samples. Second, correlations are sought for between the regolith properties and geomorphometric indices of land surface morphology and Landsat Thematic Mapper spectral response. This is done using spatially implicit Artificial Neural Networks (ANN) and spatially explicit Geographically Weighted Regression (GWR). The results indicate that the degree to which regolith properties are related to surface measurable features is limited and spatially variable.¶ ... ¶ The implications of these results are significant for anyone intending to generate spatial datasets of regolith properties. If there is a low spatial density of sample data, then the effects of landscape evolution can reduce the utility of any analysis results. Instead, spatially dense, direct measurements of subsurface regolith properties are needed. While these may not be a direct measurement of the property of interest, they may provide useful additional information by which these may be inferred.
