The article presents results of first radiocarbon analyses carried out for samples obtained from the Linear Pottery Culture settlement on site 6 in Tominy, Opatow district. Presented radiocarbon dates highly enrich current database of chronometric markings relating to the early Neolithic in the Sandomierz Upland and its northern foreland. Together with data on stylistic and typological differentiation of the vascular pottery, seem to reveal a specific course of development of local groups of the Linear Pottery Culture, which is characterized by particularly long term functioning of the music note ornamental traditions, as well as their late, little intense and retarded coexistence with the early-Želiezovce stylistic influences. These data are also a quite significant contribution both to the discussion on the overall time range of the Linear Pottery Culture, as well as the nature and course of the final stage of its development in the upper basin of the Vistula River.
