It is not even certain whether the Bastarnae were sedentary, nomadic or semi-nomadic. Tacitus' statement that they were "German in their way of life and types of dwelling" implies a sedentary bias, but their close relations with the Sarmatians, who were nomadic, may indicate a more nomadic lifestyle for some Bastarnae, as does their attested wide geographical range. If the Bastarnae were nomadic, then the sedentary "cultures" identified by archaeologists in their "lebensraum" would not represent them. Nomadic peoples generally leave scant traces, due to the impermanent materials and foundations used in the construction of their dwellings.
