| 1 | Sponge spicules in phosphorites of the Early Cambrian Gezhongwu Formation,Zhijin,Guizhou显示文摘Phosphorites occurring at the bottom of the Cambrian system contain abundant small shelly fossils,which are the prod-uct of the first episode of life explosion in the Cambrian.It was previously reported that the small shelly fossils are dominated by hy-olithids,olivooids,zhijinitids,conodontomorphs,yubelichitids,camenitids and algae,with minor amounts of sponge fossils.Large amounts of sponge spicules,diverse in form,have been found for the first time in the Gezhongwu Formation phosphorites at Shixing,Zhi-jin County,Guizhou Province,of which such spicules as diaxon-triactins,diaxon-tetractins,pentaxon-pentactins and hexon-hexactins ac-count for30%.These spicules constitute the sponge clastic phosphorites made up of sponge clastics.Meanwhile,it is also expected that the radiation and diversity of sponge animals started as early as in the earliest Early Cambrian.Habit and burying environment of sponge animal are discussed in the paper. | YANGRuidong QIANYi ZHANGJie ZHANGWeihua JIANGLijun GAOHui | 2004 | Progress in Natural Science:Materials International2004，14，10： | 8 |
