“…Based on the data from Caours, a general consideration about the Eemian lithic industries can be made after an overview of other European Eemian industries (Wenzel 2007;Locht & Depaepe 2015;Locht 2018;H erisson et al 2023). The Levallois and discoidal debitage are well represented there, but these series seem to be characterized by low technical investments and appear to be of fairly average quality.…”

“…There the end of the Saalian is marked by the gradual concentration of the fluvial dynamics in a meandering system. It is associated with the deposition of fine fluvial calcareous sands and silts that pre-dates the development of peat marking the beginning of the Eemian, in a 'Lateglacial' type environment (Deschodt et al 2023). At Waziers, the palynological study of the silty-peaty sequence provided a relatively continuous record of a vegetation succession typical of the Eemian in northern Europe (succession of phases with Pinus-Betula, Ulmus, Quercus, Corylus, and Carpinus betulus; Gauthier 2022).…”

“…In this research context, the Eemian interglacial was first demonstrated at Caours in 2002 in a thick calcareous tufa formation overlying the last fluvial terrace of the Scardon river, a little tributary of the Somme (Antoine et al 2006). Two additional Eemian sequences were later discovered in northern France at Waziers in the Scarpe Valley (peat deposit; Deschodt et al 2023) and in the Paris Basin at Resson-La Saulsotte in association with a small tributary of the Seine (calcareous tufa sequence; Dabkowski et al 2020;Jolly-Saad & Dabkowski 2021).…”

The calcareous tufa sequence and associated Palaeolithic site of Caours were discovered in 2002 during a test‐pit campaign aimed at identifying last interglacial (MIS 5e) archives in the fluvial terrace system of the Somme basin, northern France. The presence of an outstanding stratigraphical succession with four in situ Palaeolithic layers within the tufa sequence has motivated archaeological excavations of the site since 2005. The first malacological studies and U‐series ages quickly showed that the sequence was mainly deposited during the Eemian interglacial (MIS 5e). After 20 years of investigations, we propose here a summary of this multidisciplinary research project including stratigraphy, sedimentology, geochronology, geochemistry, malacology, mammals, palaeovegetation and archaeology. By combining 25 dates obtained by U‐series, ESR/U‐series, TL and OSL methods, the Caours calcareous tufa sequence is securely dated to the Eemian (123.1±2.8 ka). Based on the summary of the whole information, we propose a robust and detailed reconstruction of the modification of the valley environments between the Late Saalian and the Early Weichselian. At the scale of northwestern Europe, Caours provides a reference terrestrial molluscs record for the Eemian interglacial, including the climatic optimum, that is also described in the same layers by δ18O and δ13C analyses on calcite and by mammal remains. Moreover, the 300‐m‐long transect crossing the fluvial terrace covered by the tufa sequence and the bottom valley formation, combined with the chronology established from U‐series and OSL ages, shows that the incision of the present‐day valley, leading to the setting of the Very Low Terrace, was achieved during the first stages of the Early Weichselian (MIS 5d–5c). From an archaeological point of view, the configuration of the Caours site is unique at the scale of western Europe and demonstrates the adaptation of Neandertals to a forested environment and to fully temperate conditions during the Eemian.
