Abstract

Trace fossils from the tidal flat Tataertage Formation (Silurian) consist of at least 12 ichnogenera and 12 ichnospecies, namely, Skolithos linearis, Skolithos verticalis, Ophiom orpha nodosa, Thalassinoides suevicus, D iplocraterion parallelum, A renicolites isp., M acaronichnus segrega tis, Cy lindrichnus isp., Taen idium satanassi, Palaeophycus tubu laris, Planolites beverlegensis and Cochlichnus anguineus. These trace fossils, which are mainly p reserved in full relief and epirelief, can be known as the domichnia, fodinichnia and pascichnia of invertebrates. According to their palaeoecological and sedimentological features, these trace fossils can be divided into 3 ichnoassemblags, i. e. ①Skolithos-Tha lassinoides assemblage, forming in the sand flat sedimentary environment, mainly consists of a set of Skolithos linea ris, Tha lassinoides suevicus, M acaronichnus segregatis, D iplocraterion pa rallelum, A renicolites isp.,Cy lindrichnus isp. and so on; ②Planolites-Palaeophycus assemblage, which is p redominantly composed of Planolites beverlegensis, Palaeophycus tubu laris, M acaronichnus segregatis, Skolithos vertica lis, Ophiom orpha nodosa, Taenidium satanassi and so forth, is characterized by high diversity and abundance of trace fossils. The ichnoassemblage is associated with the mixed flat between average high tidal and average low tidal base; ③Cochlichnus-Planolites assemblage, including Cochlichnus angu ineus and Planolites beverlegensis, occurs in the mud flat sedimentary environment near average low tidal base.
