Moyjil (also known as Point Ritchie) is the site of an unusual shell deposit in south-west Victoria showing many characteristics of a midden. Earlier research established an age of 60 ka or older for the shell deposit but could not establish whether humans or animals such as seabirds were responsible for its formation. This paper, the first of six in this special issue, summarises the most recent phase (~10 years) of investigations. The site’s age is now fixed as Last Interglacial and following the stage MIS 5e sea-level maximum (i.e. younger than 120–125 ka). Fragmentation and the limited size distribution of the dominant marine shellfish (Lunella undulata syn. Turbo undulatus) confirm the site as a midden. There is also evidence for fire (charcoal and discoloured and fractured stones) and two hearth-like features, one of which has been archaeologically excavated. None of the evidence collected is able to conclusively demonstrate a human versus animal origin for the site. Significantly, a human origin remains to be disproved. These papers provide the basis for a new phase of research into the possible cultural status of the Moyjil site.

At Moyjil (Point Ritchie), a cliffed site at the mouth of the Hopkins River at Warrnambool, south-eastern Australia, an erosional disconformity of Last Interglacial age on both a rock stack and the adjacent headland represents a surface of possible human occupation. Shells of edible marine molluscs occur on the disconformity, together with a distinctive population of transported stones derived from a calcrete of MIS 7 age and bearing variable dark grey to near-black colouration suggestive of fire. Experimental fire produced similar thermal alteration of calcrete. A strong correlation exists between intensity and depth of dark staining on one hand and increased magnetic susceptibility on the other. Thermal luminescence analyses of blackened stones provide ages in the MIS 5e range, 100–130 ka, consistent with independent stratigraphic evidence and contemporaneous with the age of the surface on which they lie. The distribution of fire-darkened stones is inconsistent with wildfire effects. Two hearth-like features closely associated with the disconformity provide further indications of potential human agency. The data are consistent with the suggestion of human presence at Warrnambool during the Last Interglacial.

Claims for a human presence in Australia beyond 60,000 years ago must have a strong evidence base associated with rigorous methodology and intense scrutiny. In this light we present excavation results for Charcoal and Burnt Stone Feature #1 (CBS1) located within coastal dune sediments at Moyjil (Point Ritchie), Warrnambool, that independent geomorphic and OSL dating indicates is of Last Interglacial age (~120,000 years ago). While on plausibility grounds the cultural status of a feature of such great antiquity in Australia is unlikely, a cultural origin for CBS1 is less easily dismissed if assessed with an age-independent methodology. A broad range of macroscale discrimination criteria has been used to assess whether CBS1 is either a cultural hearth or a natural feature such as a burnt tree stump. On balance, evidence marginally supports a cultural origin over a natural origin. However, the absence of associated stone artefacts and faunal remains and the presence of burnt root wood precludes definitive statements on the cultural status of the feature. Our case study is methodologically instructivein terms of the potential complexities and issues of equifinality involved in the archaeological identification of ancient hearths.

Shelly deposits at Moyjil (Point Ritchie, Warrnambool), Victoria, together with ages determined from a variety of techniques, have long excited interest in the possibility of a preserved early human influence in far south-eastern Australia. This paper presents a detailed analysis of the stratigraphy of the host Bridgewater Formation (Pleistocene) at Moyjil and provides the context to the shelly deposits, evidence of fire and geochronological sampling. We have identified five superposed calcarenite–palaeosol units in the Bridgewater Formation, together with two prominent erosional surfaces that may have hosted intensive human activity. Part of the sequence is overlain by the Tower Hill Tuff, previously dated as 35 ka. Coastal marine erosion during the Last Interglacial highstand created a horizontal surface on which deposits of stones and shells subsequently accumulated. Parts of the erosional surface and some of the stones are blackened, perhaps by fire. The main shell deposit was formed by probable mass flow, and additional shelly remains are dispersed in the calcareous sand that buried the surface.

Characteristics of marine shellfish and other species found in a Last Interglacial (LIG) shell deposit at Point Ritchie (Moyjil) at Warrnambool in south-western Victoria have been compared to those from modern and LIG natural beach deposits, Holocene Aboriginal middens and modern Pacific Gull (Larus pacificus) middens. The research was aimed at determining whether properties such as shell speciation, size or taphonomy could identify the mechanism responsible for formation of the Moyjil deposit. Marine species found in the Moyjil deposit resemble those found in both Aboriginal and Pacific Gull middens and are non-discriminatory for the two types. Taphonomic properties such as wear and breakage pattern of opercula of the dominant species, Lunella undulata (syn. Turbo undulatus), are non-diagnostic because of post-depositional erosion and transport effects in the available specimens. The size of L. undulata opercula show clear bias toward larger individuals, in common with Aboriginal and seabird middens, when compared to natural shell deposits. Statistical analysis (ANOVA) of the size distributions shows a greater similarity of the Moyjil deposit to the two seabird middens than the two Aboriginal middens. Small individuals (operculum L. undulata as well as smaller shellfish species are absent from the seabird middens studied, but they are present in Aboriginal middens and in the Moyjil deposit. Overall, we conclude that shell properties alone are not sufficient to distinguish which predator collected the shellfish occurring in the deposit.

In the autumn of 1913, Mr. T. C. Cantrill, F.G.S., of the Geological Survey, drew the writer's attention to the possibility of finding flint artefacts in the surface soils of Hinckley and neigh-bourhood wherever the chalky boulder clays and gravels were in evidence. During his survey of the drift in this district in that and the following year, he himself found a lozenge-shaped scraper (No. 163, Plate LXVIII) in a field at Sapcote, and also five spalls of unmistakable human origin in other neighbouring localities.In the winter of that year, Mr. F. C. Grimes and I began a systematic search which by the following spring had resulted in sufficient material to encourage us to further efforts, and the following notes are the result of a by no means exhaustive survey during that and the two following winters.

Abstract. Coastal southeast South America is one of the classic locations where there are robust, spatially extensive records of past high sea level. Sea-level proxies interpreted as last interglacial (Marine Isotope Stage 5e, MIS 5e) exist along the length of the Uruguayan and Argentinian coast with exceptional preservation especially in Patagonia. Many coastal deposits are correlated to MIS 5e solely because they form the next-highest terrace level above the Holocene highstand; however, dating control exists for some landforms from amino acid racemization, U∕Th (on molluscs), electron spin resonance (ESR), optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), and radiocarbon dating (which provides minimum ages). As part of the World Atlas of Last Interglacial Shorelines (WALIS) database, we have compiled a total of 60 MIS 5 proxies attributed, with various degrees of precision, to MIS 5e. Of these, 48 are sea-level indicators, 11 are marine-limiting indicators (sea level above the elevation of the indicator), and 1 is terrestrial limiting (sea level below the elevation of the indicator). Limitations on the precision and accuracy of chronological controls and elevation measurements mean that most of these indicators are considered to be low quality. The database is available at https://doi.org/10.5281/zenodo.3991596 (Gowan et al., 2020).

Abstract. This study investigates the response of Red Sea circulation to sea level and insolation changes during termination II and across the last interglacial, in comparison with termination I and the Holocene. Sediment cores from the central and northern part of the Red Sea were investigated by micropaleontological and geochemical proxies. The recovery of the planktonic foraminiferal fauna following high salinities during MIS 6 took place at similar sea-level stand (~50 m below present day), and with a similar species succession, as during termination I. This indicates a consistent sensitivity of the basin oceanography and the plankton ecology to sea-level forcing. Based on planktonic foraminifera, we find that increased water exchange with the Gulf of Aden especially occurred during the sea-level highstand of interglacial MIS 5e. From MIS 6 to the peak of MIS 5e, northern Red Sea SST increased from 21 °C to 25 °C, with about 3 °C of this increase taking place during termination II. Changes in planktonic foraminiferal assemblages indicate that the development of the Red Sea oceanography during MIS 5 was strongly determined by insolation and monsoon strength. The SW Monsoon summer circulation mode was enhanced during the termination, causing low productivity in northern central Red Sea core KL9, marked by high abundance of G. sacculifer, which – as in the Holocene – followed summer insolation. Core KL11 records the northern tip of the intruding intermediate water layer from the Gulf of Aden and its planktonic foraminifera fauna shows evidence for elevated productivity during the sea-level highstand in the southern central Red Sea. By the time of MIS 5 sea-level regression, elevated organic biomarker BIT values suggest denudation of soil organic matter into the Red Sea and high abundances of G. glutinata, and high reconstructed chlorophyll-a values, indicate an intensified NE Monsoon winter circulation mode. Our results imply that the amplitude of insolation fluctuations, and the resulting monsoon strength, strongly influence the Red Sea oceanography during sea-level highstands by regulating the intensity of water exchange with the Gulf of Aden. These processes are responsible for the observation that MIS 5e/d is characterized by higher primary productivity than the Holocene.

AbstractEemian lake deposits in Grande Pile and Ribains, France, correlate with marine isotope substages (MIS) 5e and 5d as delimited in two pollen-bearing deep-sea cores off Portugal. The Eemian forests in France lasted for approximately 20 millennia, from at least 126,000 to ca. 107,000 yr B.P. Oscillatory climate deteriorations began about 115,000 yr ago. An intense cold spell affected the region approximately 110,000 yr ago.

AbstractA new astronomical calibration method for long pollen records from southern Europe is applied to the last interglacial interval of the Ioannina sequence, northwestern Greece. This shows that the last interglacial in this region, as defined by the presence of forest communities, lasted ca. 15,500 yr, from 127,300 to 111,800 yr B.P. Interglacial conditions developed within marine isotope substage (MIS) 5e and persisted into MIS 5d, lagging changes in global ice volume.
