The status of cambrian system in the 2004 version of the international stratigraphical chart is reviewed with comments on the gssp for the base of the system and the current subdivision of the system , the gssp for the newly ratified furongian series and paibian stage , and the time span of the system and its series 摘要評述了國際地層委員會最新公布的2004年版“國際地層表”的寒武系部分,包括它的底界全球層型和點位的確定和存在的問題、寒武系當前的再劃分情況、芙蓉統和排碧階及其底界全球層型剖面和點位、寒武系的時代跨度。

When i view all beings not as special creations , but as the lineal descendants of some few beings which lived long before the first bed of the cambrian system was deposited , they seem to me to become ennobled 當我看到所有的生物不是特殊的創造品而是幾種遠在志留紀層還未形成之前就已存在的生物的直系后代,他們就似乎變得更加高貴了。

A new global chronostratigraphic subdivision of cambrian system into 4 series and 10 stages has been developed to replace the tripartite traditional framework of the system , which has been used for more that 170 years 摘要重新劃分全球寒武系年代地層為4統和10階,取代了國際地學界沿用了近170年的上、中、下3統的傳統劃分框架。
