Trilobites described from the lower part of the Asushan Formation (Pridolian or late Ludlovian to Pridolian) of Santanghu, Barkol, NE Xinjiang, comprise Ananaspis fecunda Barrande, Pacificurus sp. and Cheirurus barkolensis sp. nov. The Silurian fauna from Barkol (northeast Junggar) and Utubulak(northwest Junggar) are intimately ralated to the late Silurian trilobites and graptolites of Kazakhstan and central Europe, especially the Bohemian area. A review on the Pridolian, or late Ludlovian to Pridolian trilobites from five areas in China is given. Ananaspis and Pacificurus is recorded from China for the first time.
