The Mas des Caves site at Lunel-Viel, Southern France, is a complex of several caves, developed in Miocene limestone, that have yielded a rich archaeo-palaeontological sequence attributed to the Middle Pleistocene with abundant vertebrates and lithic artefacts. The first caves (LVI, II and III), discovered in 1800, were excavated at the beginning of the 19th century (Serres et al., 1828) before falling into oblivion for over a century. The main cavity is LVI , when LVII and III are smaller subparallel galleries not connected to LVI. In the early 1970s, research was conducted in the main gallery by E. Bonifay who discovered an extension named LVIV and the natural entrance (sinkhole, doline) both completely closed now. Recently, a multidisciplinary approach has been set up (DRAC-SRA Occitanie) to contextualize the ancient collections with the recent ones and to allow a better understanding of the site formation, palaeoenvironmental and behavioral history of the animals and humans who lived there (Brugal et al., 2021). The previous chronology based on faunal evidence yields important biomarkers (including new genus and species/subspecies) making Lunel-Viel a major Middle Pleistocene site in the European record. Among various dating techniques used in this study, trapped-charged methods such as combined ESR/U-series and pIR-IR 290 were applied on fossil tooth enamel and on K-feldspars, respectively. The results obtained by both methods are in agreement and suggest a period of human occupation between 300 and 200 ka. This age range matches well with the composition of the faunal assemblage attributed to the second part of the Middle Pleistocene (biochronology) and which constrains the occupation to a cool/temperate and humid period which could be contemporaneous with the MIS7 (Lisiecki and Raymo, 2005) cited in figure 5 legend. • Multi-method dating approach to constrain the sequence of Lunel-Viel cave site, LVI. • The radiometric results are compared with other palaeoenvironmental data. • Ages range between 200 and 300 ka, in agreement with the faunal assemblage. • Possibly contemporaneity with a temperate period corresponding with the MIS7.
