The Final Palaeolithic in the lithuanian coastal zone has so far been represented only by a few archaeological finds from individual contexts, and a small number of archaeological excavations. however, their analysis has not revealed much regarding the technological development of hunting implements and work tools, or the choice and the use of necessary raw materials, and little data has been provided on the chronological aspects, or the connection between settlement locations and the changing level of the Baltic sea. This paper presents the latest archaeological material from the Final Palaeolithic in the lithuanian coastal area, based on the three sites at Aukštumala upland bog, and stray finds found in the area. The article focuses on technological and typological aspects of lithics related to swiderian culture. The results of the study show that, with the shortage of flint raw material, Final Palaeolithic societies at Aukštumala relied on smaller and narrower blades, and compensated for the lack of flint raw material by using other, locally available metamorphic rocks.
