EARLY PERMIAN TRACE FOSSILS FROM THE EJIN BANNER, INNER MONGOLIA

Lower Permian trace fossils described herein were first found from Gu- dongjing in the southern part of the Ejin Banner,Inner Mongolia.Seven iden- tified ichnospecies and one unnamed form are listed below: Scalarituba missouriensis Weller Helminthoida labyrinthica （Heer） Helminthopsis hierographica Heer Cochilichnus sp. Chondrites expansus Sternberg Chondrites arbuscula Fiser-Ooster Planolites octichnus Chamberlain Unnamed form The trace fossils listed above closely resemble Ouachita （Penssylvanian- Permian） flysch trace fossils from southeastern Oklahoma （Chamberlain, 1971, 1978）. Among the trace fossils memtioned above, Pascichnia is predominant and Fodinichnia is subordinate. Cubichnia and Domichnia commonly occurring in the neritic facies are absent. So speaking roughly, the trace fossils should be- long to Nereites ichnofaces characteristic of an abyssal geosynclinal region.
