Veselovsky was the first to excavate Afrasiab, the oldest part of Samarkand, as well as several notable kurgans in Southern Russia and Ukraine, notably the Solokha, Kostromskaya and Maikop kurgans. Some of the finest examples of Scythian art, including the Solokha comb, were discovered by Veselovsky and his team.
