Discussion on Taphonomy of Early Metazoen Biota in China

Key words: 
• early metazoen biota /
• sedimentary evironment /
• taphonomy

Abstract: The following results are obtained from the study of taphonomic characteristics fossil taphonomic sequence and sedimentary sequence of early metazoen biota discovered in China:(1)The emdedded and preserved condition is controlled by event layer(tempestite or turbidite)ard sedimentation rate takes main part in fossil embedition and preservation.(2)Close relationship preservation of the early metazoen biota between sea-level changes,this is,which always occur in transgressive system of shallow water bay and restricted sea, early metazoen biota occur in the shelf margin systems. Based on sedimentary evironments of the early metazoen biota.two buried models of the early metazoen biota are established Eventualy,it is indicated that new early metazoen biota may be discovered by above-mentioned condition which is benefit to preserve biota.
