The fossil corals described in this paper were collected by Li Haomin from the Cape Melville Formation at Crab Mound and Lava Crag respectively in Melville Peninsula,King George Island,South Shetland Island,Antarctica in 1992.They are assigned to Flabellum rariseptatum which had been described first by Roniewicz and Morycowa in 1985.The fossil community of genus Flabellum was found from the Antarctic region but many forms from some other comtinents.The coral bearing formation contains simultaneously some other fossils such as bivalves,burchiopods,gastropods,belemnites and crabs.The character of the sediment indicates that this sequence formed in shallow marine environment,probably in a bay (Birkenmajer,1984),even though there was a ahermatypic corals.The fossil corals are probably early Miocenein age.
