These trace fossils, which are m ainly preserved in full relief and epirelief, can be known as the dom ichnia, fodinichnia and pascichnia of invertebrates. According to their palaeoecological and sedimentological features, these trace fossils can be divided into 3 ichnoassemblags, .i e. ①Skolithos-Thalassinoides assemblage, form ing in the sand flat sedimentary environment, mainly consists of a setof Skolithos linearis, Tha lassinoides suevicus, Macaron ichnus segrega tis, D iplocra terion parallelum, Arenicolites isp. , Cylindrichnus isp. and so on;②P lanolites-Palaeophycus assemblage, which is predom inantly composed ofP lanolites beverlegensis, Pa laeophycus tubularis, Macaronichnus segregatis, Skolithos verticalis, Ophiomorpha nodosa, Taenidium satanassi and so forth, is characterized by high diversity and abundance of trace fossils. The ichnoassemblage is asso- ciated with the m ixed flat between average high tidal and average low tidal base;③Cochlichnus -Planolites assem- blage, includingCochlichnus anguineus and Planolites beverlegensis, occurs in the mud flat sedimentary environment near average low tidalbase.
