“…suppression during deposition followed by uplift during and after deglaciation, would require an ice sheet much larger than present during MIS 2, as for the latter period the study area is predicted to have been situated on the southern side of the fore bulge (Busschers et al, 2007;Kiden et al, 2002). Current estimates on MIS 4 ice extent suggest the BIIS and FIS in the North Sea area were smaller compared to the maximum ice extent of the LGM (Batchelor et al, 2019;Dalton et al, 2022;Toucanne et al, 2023), although uncertainties on the size, shape and timing of growth of the BIIS and FIS during MIS 4 remain.…”

“…Major ice expansion in the NH during the first half of MIS 4 (ca. 72-65 ka) resulted in an NH ice limit that was close to the maximum ice extent of the Last Glacial Maximum (LGM, MIS 2), although with different configurations (Batchelor et al, 2019;Dalton et al, 2022;Ruddiman & McIntyre, 1981;Toucanne et al, 2023). Global sea levels dropped as water was captured in growing polar ice caps.…”

“…During most of MIS 4, the southern North Sea was dry land with fluvial systems eroding parts of previously deposited marine sediments (Busschers et al, 2007;Törnqvist et al, 2000). The British-Irish ice sheet (BIIS) and Fennoscandian Ice Sheet (FIS) probably did not merge during MIS 4, providing a potential northern drainage route for NW European rivers (Toucanne et al, 2023).…”

The Late Pleistocene Marine Isotope Stage (MIS) 5 – MIS 4 transition (at ca. 75 ka) is globally known to correspond to a period of strong cooling and sea‐level lowering. Terrestrial records indicate the transition had a large impact on terrestrial environments, but the impact on coastal and shallow‐marine areas is poorly documented due to a lack of well‐dated, continuous archives caused by erosion during succeeding glacial lowstands. The extensive offshore deposits of the Brown Bank Formation in the southern North Sea yield a valuable record of this transition in a shallow‐marine environment. We show that the southern North Sea experienced subarctic marine conditions with a high input of terrestrial material during the MIS 5–4 transition. These continued marine conditions, which have not been described earlier for northwestern Europe, show that sea level remained relatively high, and lagged cooling on land inferred from lipid‐biomarker palaeothermometry. The time‐lag between terrestrial cooling and sea‐level fall created a sediment preservation window during the onset of MIS 4 in a shallow‐marine environment. Our record captures changes in both the terrestrial and shallow‐marine environments, and allows for linking terrestrial and marine records of the MIS 5–4 transition in NW Europe.

“…Approximate maximum extent of the Fennoscandian ice sheet within the potential period of Middle Palaeolithic hominin site occupation at Königsaue (Layer A) 90 , 143 – 148 correlated with MIS 4 (ca. 71–57 ka BP) 71 , 149 , 150 is shown by the thick white line. The maximum ice sheet extent during the early Upper Palaeolithic hominin occupation of Breitenbach is further north 71 , 150 and therefore is not visible on the current map.…”

Interpretations of Late Pleistocene hominin adaptative capacities by archaeologists have focused heavily on their exploitation of certain prey and documented contemporary behaviours for these species. However, we cannot assume that animal prey-taxa ecology and ethology were the same in the past as in the present, or were constant over archaeological timescales. Sequential isotope analysis of herbivore teeth has emerged as a particularly powerful method of directly reconstructing diet, ecology and mobility patterns on sub-annual scales. Here, we apply 87Sr/86Sr isotope analysis, in combination with δ18O and δ13C isotope analysis, to sequentially sampled tooth enamel of prevalent herbivore species that populated Europe during the Last Glacial Period, including Rangifer tarandus, Equus sp. and Mammuthus primigenius. Our samples come from two open-air archaeological sites in Central Germany, Königsaue and Breitenbach, associated with Middle Palaeolithic and early Upper Palaeolithic cultures, respectively. We identify potential inter- and intra-species differences in range size and movement through time, contextualised through insights into diet and the wider environment. However, homogeneous bioavailable 87Sr/86Sr across large parts of the study region prevented the identification of specific migration routes. Finally, we discuss the possible influence of large-herbivore behaviour on hominin hunting decisions at the two sites.

The timing and magnitude of the British–Irish Ice Sheet between Marine Isotope Stages 5d and 2: implications for glacio‐isostatic adjustment, high relative sea levels and ‘giant erratic’ emplacement

The extent, chronology and dynamics of the pre‐Marine Isotope Stage (MIS) 2 last British–Irish Ice Sheet (BIIS) are not well known. Although the BRITICE‐CHRONO Project has detailed the maximum extent and retreat phases of the last BIIS for the period after 30 ka and into the Last Glacial Maximum (LGM), the Project identified several pre‐existing datasets and generated new data that implied glaciation pre‐dating the LGM but which post‐dated the Last Interglacial (Eemian; MIS5e); these data are reviewed here. There are no dated till units but are other indicators clearly indicative of glaciation: deep‐sea ice‐rafted detritus flux into the adjacent NE Atlantic, cosmogenic rock‐exposure age dating from glaciated surfaces in Wales and the island of Lundy (Bristol Channel), and optically stimulated luminescence (OSL) ages of proximal glacifluvial sequences on the Isle of Lewis (Outer Hebrides) and in the Cheshire Basin. Taken together these indicate BIIS inception during MIS5d, growth into MIS4 and evidence for dynamic retreat–advance phases during MIS3. OSL evidence for high relative sea level indicated by raised beaches in southern Ireland during MIS4 and 3 at a time of lowered glacio‐eustatic sea level indicates substantial glacial isostatic loading, explained by the early growth of the BIIS during the last cold stage. High relative sea level during MIS4 and 3 coincident with adjacent calving ice sheet margins provides an explanation for the rafted giant erratics found around the shores of southern Britain and Ireland.
