日本志留纪至三叠纪牙形刺生物地层

SILURIAN TO TRIASSIC CONODONT BIOSTRATIGRAPHY IN JAPAN

本文系统地回顾了日本志留纪至三叠纪牙形刺研究的历史和现在的成果。志留纪牙形刺只有少数零星的报道，没有建立化石带；早泥盆世已建立了５个牙形刺组合，没有中、晚泥盆世的记录；石炭纪有８个牙形刺带，其中晚石炭世３个牙形刺带；二叠纪５个牙形刺带或动物群，其中，中、晚二叠世各１个带（动物群）；三叠纪可划分出１４个牙形刺带。

This paper gives a general review on the research history and present information of conodonts in Japan.Since very few conodonts have been found from Silurian,no conodont zones have been erected in this system. However,32 conodont zones or assemblages have been found from Devonian to Triassic in Japan,including 5 Early Devonian, 8 Carboniferous,5 Permian and 14 Triassic conodont zones or assemblages.
