The East Baltic Stone Age is well known for its rich array of bone and antler artefacts. The collections consist of stray finds as well as inventory from stratified settlement sites. Seven hunting and fishing tool complexes, made from bone and antler, were singled out in Latvia, characterising each stage of the Baltic Stone Age. The oldest of these complexes was formed at the very end of the Late Glacial period when the ice sheet retreated and the conditions for human habitation were created. This complex consists of 18 bone and antler artefacts, harpoons of archaic forms and spearheads, found in Latvia and Lithuania. Unfortunately, they are all stray finds and determined as Late Palaeolithic only typologically. Harpoons in similar morphological forms are known from all of northwest and Central Europe, associated with Late Palaeolithic reindeer hunter cultures. Some of the finds were made from reindeer antler. The new carbon 14 data of reindeer bones, obtained in Helsinki University by H. Jungner, testified to the presence of reindeer in the Eastern Baltic from Alleröd times till the beginning of the Preboreal climatic period.
In the light of the present findings from Pagóry Chełmskie the flint deposited on the surface occurs in two types. One type often resembles the shaft varieties from Volhynia, Podolia and Volhynian Polesie, or even Podlasie. Most Final Palaeolithic finds represent the settlements of cultures with point-tools tradition, mostly Swiderian Culture, some of them are connected with an undetermined culture with backed points, one site with the inventories of Magdalenian Culture.
Today four different expressive versions of local Epigravettian industries represented by groups of sites can be defined in the Middle Dnieper basin: Mezinian, Ovruchian, Mezhirichian and Yudinovian industries. In addition, two other quite specific ones are represented by single collections: Eliseevichi 1 and Zhuravka.
