Swiderian

Refers to the style and culture that is named after the site at Swidry, Poland, and existed in the areas of Poland, Romania, Russia, and elsewhere. It developed in the late Paleolithic Period, though it continued and flourished in the Mesolithic. It is particulalarly characterized by distinctive flint tools, including small, assymetrical tanged blades, arrowheads, and tranchet axes. It seems to be related to the Campignian culture that flourished further south.
