The excavation of the simple dolmen at Tiarp, Falbygden, dating to around 3500 BCE, has provided important information for the understanding of the megalithic and early TRB in southern Scandinavia and northern Central Europe. The absolute chronological dating shows that dolmens were erected at about the same time between Falbygden and Altmark, before the main passage grave architectural phase. Although fragmented and affected by taphonomic processes, the bone assemblage provides insights into the burial practices. At least twelve individuals, from neonates to elderly, had been buried within the chamber. The predominance of hand and foot bones suggests that they were primary inhumations. Their isotope values indicate an already agrarian society, which, however, was based only to a certain extent on agriculture. Insofar, the dolmen at Tiarp signals transformations – not only in respect to the introduction of agriculture but also regarding ritual practices – within the Early and Middle Neolithic.
