Abstract：Abundant Wenlock animal fossils are found in the succession of the volcanoclastic rocks intercalated with limestones which were considered as the Late Devonian Ta'erbahatai Formation,including corals Halysites hoboksarensis ,H.sp.,Meso-favosites sp.,brachiopods Atrypa sp.,Eospirifer radiates ,trilobites Encrinuroides sp.,Encrinurus sp.1,E.sp.2, Cheirurus sp.,Sthenarocalymene sp.,Machaeridia Lepidocoleus sp.,stromatoporoids and so on.Based on lithological associ-ation and stratal correlation,the succession is re-assigned to the Wenlock Shaerbuer Formation,where abundant facies indica-tors were discovered.Main facies indicators include reefoid corals and stromatoporoids,graded bedding,convolute bedding, flame structure and storm deposits.It is concluded that the Wenlock Shaerbuer Formation was formed in the open platform environment with volcanic activities in tropical and subtropical zones.
