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.
