The Corded Ware culture in the Eastern Baltic: new evidence on chronology, diet, beaker, bone and flint tool function 1.0. Introduction The peoples of the Corded Ware culture (hereafter CWC) are traditionally regarded as mobile stockbreeders who brought animal husbandry into the Eastern Baltic between ca. 2900–2300 cal BC. The presence of domesticated faunal remains within CWC contexts as well as stable isotope data obtained on human bone collagen has demonstrated that terrestrial derived protein was preferentially consumed when compared with the preceding Subneolithic hunter- gatherers who relied heavily on aquatic resources (Lõugas et al., 2007; Piličiauskas et al., 2017b; d). Throughout Europe the CWC suddenly appears and differs to all preceding cultures in all aspects of material culture. Thus, nearly 100 years ago it was postulated that the CWC was brought into Europe by a mass migration of pastoralists from the Pontic steppe (Childe, 1926; Gimbutas, 1979); a hypothesis that has been critiqued numerous times (e.g. Lang, 1998; Furholt, 2014; Beckerman, 2015) until recently proved by genetic analyses (Allentoft et al., 2015; Haak et al., 2015; Saag et al., 2017; Mittnik et al., 2018). This contribution focuses on several CWC graves in the Eastern Baltic. Whilst CWC human remains are highly sought-after for AMS radiocarbon ( 14 C) dating, stable isotopic and genetic analyses, less than a third are available for scientific analysis. Moreover, human remains are, in general, poorly preserved. This has largely been attributed to the acidic soils in the region, which have affected the organic component of the bones, but also unsolicited excavations and the mishandling of materials in storage (Žukauskaitė, 2004). In 2017, one of us (GP) was fortunate to discover and excavate a new CWC inhumation at the site of Benaičiai in North West Lithuania. It was during these investigations when we realised Belarusian CWC burials are also poorly understood. A grave found inside the flint mine at Krasnasieĺski is one such example. Although the remains were well preserved it has not been directly AMS radiocarbon ( 14 C) dated. In order to rectify this imbalance, reconstruct the diets of these two individuals and place them into the wider context, here, we present new osteological, radiocarbon and stable isotope data from the two skeletons. To supplement the aforementioned dietary reconstruction we undertook organic residue analysis of two CWC beakers. Prior to this study it was unknown why beakers were placed 1
