【Abstract】 The Xieertala Formation was established on the western slope of Da Hinganling (Great Hingan)near by Hailar in 1976.Based mainly upon the determination of brachiopods,the age of the formation has been recognized as Late Carboniferous, but the coral fauna of the Xieertala Formation indicated that the age should be Early Carboniferous.This coral fauna consists merely of very few small solitary corals and its generic assemblage,such as.Zaphrentites,Zaphrentoides, Trochophyllum,Cyathaxonia and Amplexus etc.,clearly shows a Early Carboniferous feature,although its dominant species are endemic.Whereas in West Europe the characteristic forms of the Tournaisian corals are dominated by"Zaphrentis",the Xieertala coral fauna is comparable with the"Zaphrentis"konincki subzone(Z2) of England except for disappearence of caninid corals.Our co ral assemblage is also similar to some types of American Mississippian corals, therefore the Xieertala Formation seems to be able to compare with the Keoikuk Limestone or the New Providence Shale of the Osagean Series of Mississippianin the United States.更多还原
