Abstract

Abstract: Since “Donghe sandstone" had been found in Well Donghe 1 in 1990, antiarcha fossil was found in Well Cao 2 of Caohu area in 1993.Based on paleontology and stratigraphy studies in recent years, conodont and sporopollen were successively found nearby boundary of Carboniferous-Devonian, so “Donghe sandstone" is put in Devonian.Discovery of Devonian fish fossil in Well Tazhong 45 offered reliable evidence for “Donghe sandstone"belonging to Devonian in Tazhong area.

Key words: Tarim basin, Devonian, Carboniferous, Vertebra paleontology, Formation, Geologic age
