Budurovignathus和Pseudofurnishius牙形类动物群是世界上具有重要地层研究价值且比较稀有的牙形类动物群,迄止目前,在滇西保山地区发现:Budurovignathus hungaricus(Kozur et Vigh)、B.mungoensis(Diebel)、B.aff.mungoensis(Diebel) or B.baoshanensis sp.nov.、B.diebeli(Kozur et Mostler)、Pseudofurnishius socioensis(Gullo et Kozur),P.murcianus(Van Den Boogaard)和Pseudofurnishius sp.A等重要的属种,本次发现,为云南保山地区中—晚三叠世地层提供有力的生物年代约束,拓展了三叠世牙形石生物带,同时也丰富了中国这两个牙形类动物群的资料。 |

Abstract: |
The conodonts Budurovignathus and Pseudofurnishius are of important stratigraphic values and relatively rare in the world. The following conodont species have been found in the Baoshan region, Yunnan, including Budurovignathus hungaricus (Kozur et Vigh), B. mungoensis (Diebel), B. aff. mungoensis (Diebel) or B. bashanensis sp. nov., B. diebeli (Kozur et Mostler), Pseudofurnishius socioensis (Gullo et Kozur), P. murcianus (Van Den Boogaard), Pseudofurnishius sp. A et al. The findings in this study may provide the biochronologic constraints on the Middle to Late Triassic strata in the Baoshan region, Yunnan, expand the extents of the Triassic conodont biozones, and contribute valuable information to the study of the conodonts Budurovignathus and Pseudofurnishius in China. |
