摘要：
Trace fossils Phymatoderma melvillensis isp. nov., Thalassinoides isp., ? Nereites isp. and Planolites isp. are reported from the glacio-marine sediments of the Cape Melville Formation (Lower Miocene) of King George Island, West Antarctica. Their occurrence and strong bioturbation of sediments point to an offshore or deeper (outer shelf or upper slope) environment. Deep marine crab Antarctidromia inflata Forster, 1985, has been found in Thalassinoides isp. The tracemaker (? crustacean) of Phymatoderma melvillensis re-reworked pelletal sediments probably during times of food deficiency.
