摘要
奥陶纪笔石体演化历程经历了四次复杂化事件 ,研究表明 :笔石体复杂化现象的出现和消失与海平面的升降变化关系密切 ,即笔石体的复杂化大致始于最大海泛面上 。
Due to the environmental pressure,Graptolite simplified itself during its evolution. Rhabdosome complication,in such a background,is significantly not only related to its evolution history ,but also to Graptolitic biostratigraphy. The authors assure that the appearance and disappearance of rhabdosome complication coincided with the rhythm of sea level changes,starting at the maximum flooding surface (mfs) and terminating at the beginning of regression.
