“…(i) The relatively small aliquot sizes under consideration here (~360 grains per disc) should still permit some basic insights into any enhanced D e scatter related to significant bleaching complications, as has been demonstrated in several multigrain pIR‐IR studies using comparable D e measurement configurations (e.g. Arnold et al ., 2022; Priya et al ., 2022). (ii) The replicate single‐grain TT‐OSL results obtained in this study provide a semi‐independent means of examining any biasing multigrain averaging effects related to heterogeneous bleaching (see Discussion below).…”

SanQuirce is an open-air archaeological site situated on a fluvial terrace in the Duero basin (Palencia, northern Iberia). This paper presents new and consistent chronologies obtained for the sedimentary sequence using post-infrared infrared stimulated luminescence (pIR-IR) dating of K-feldspars and single-grain thermally transferred optically stimulated luminescence (TT-OSL) dating of quartz. The new dating results indicate that the sequence is older than ~200 000 years and place San Quirce Level III within marine isotope stages (MIS) 8 and 7, between 274 ± 13 ka and 238 ± 13 ka. The main lithic assemblage at San Quirce comes from Level III. The predominant tool types found in this level are hammerstones, manuports and flakes, with a small proportion of cores and a significant presence of denticulates. Adaptation to local environmental conditions resulted in distinctive cultural habits, which were embedded in the cultural tradition of hominins occupying the site during the final third of the Middle Pleistocene. San Quirce preserves a simple cultural tradition that was employed by local hominins to engage in a diverse array of activities, and highlights the cultural diversity that appears to have been a characteristic feature of the Lower to Middle Palaeolithic transition 300-200 ka.

“…In particular, transportation of predominantly wellbleached, externally derived sediments through the closed cave system is likely to have resulted in the entrainment of grains from pre-existing cave floor sediments, and their subsequent translocation to deeper parts of the cavity along with the more recently bleached grain populations (e.g. Prideaux et al, 2010;Jankowski et al, 2016;Arnold et al, 2022;Priya et al, 2022). This interpretation is in keeping with the complex accumulation histories apparent for some of the layers from sedimentological and thin-section analyses; including Layer 2, a dry grain-flow deposit (Figures 6A, 6B), Layer 8, which represents an intruded fill that likely incorporated remobilised deposits originally preserved elsewhere in the cavity, Layer 10, which was deposited under sheet wash or standing water conditions (Figure 6F), and Layer 11, which includes re-transported cave pearls originating from upslope sources (Figure 7A).…”

The Wellington Caves were the first Australian locality from which Europeans collected and analysed vertebrate fossils. Within this system, Cathedral Cave contains Australia's stratigraphically deepest sequence of fossil‐bearing infill sediments, the age and depositional history of which has been poorly understood. Here we present results from a new excavation of the upper 4.2 m of the deposit, reanalysing the stratigraphy, petrography, sedimentology and geochemistry, and employing optically stimulated luminescence dating, radiocarbon dating and Bayesian age modelling to establish a robust chronology. We recognise 13 sedimentary layers and sublayers in two stratigraphic units. Unit 2 accumulated between 72 000 ± 5000 and 38 000 ± 7000 years ago as sediments and animals entered through a now‐blocked ceiling hole. Accumulation halted for around 30 000 years when the hole closed. Unit 1 accumulated when deposition was reinitiated around 7000 ± 2000 years ago, continuing through to a few hundred years ago. Our chronology refutes earlier dating of the deposit, which suggested that extinct Pleistocene megafauna taxa persisted locally until the Last Glacial Maximum. It confirms the deposit as one of the few in Australia that formed during the interval of major environmental upheaval marked by the arrival of humans, variable climate and the extinction of many megafaunal species.
