“…One of the co-authors (F. Cousseau) was the first to multiply the application of these new tools to the study of Western European megalithic buildings, by combining them with a geoarchaeological approach (Cousseau, 2023) 6 . Thus, he was also the first to propose a reading of the geological and geomorphological characteristics of the monoliths that make up the internal space of Western European megalithic monuments, based on work conducted, among others, on the alignments of Carnac (Brittany, France) (Mens, 2008;Mens et Large, 2009;Mens et al, 2022;Sellier, 1991Sellier, , 2013Sellier, , 2018. This practice has since been democratized in Western Europe and has been applied to Neolithic megalithic monuments which take the form of large burial mounds made largely of dry-stone walls, formed from blocks of small module (Cousseau, 2023;Gouézin, 2022;Gouézin et al, 2019;Linares-Catela, 2017;van der Reijden, 2020).…”
