Artifacts identified as belonging to the "Comb Ceramic Culture" have been found at sites from Northern Finland to Eastern Prussia. Burials associated with the culture often include figures of animals, birds, snakes and humans carved from bone and amber[3] beginning from the middle of the 4th millennium BC.[4] Until the early 1980s, the scholarly consensus held that the appearance of Comb Ceramic culture artifacts was associated with the arrival of Baltic Finns (ancestors of the Estonians, Finns, and Livonians) on the shores of the Baltic Sea.
