摘要
It is a big find that Ostracod was discovered in the lower flora macro body algae of the lower Sinian Lantian Formation in southern Anhui Province. According to the features of the texture, structure, shell and soft body of the fossils, these Ostracods are classified into the Arthropoda-Crustacea’-Ostracoidau-Archaeostaidae-Sinogella （gen. nov.）-S. lantianensis（gen. etsp. nov.）. They serve as a basis to discuss the history of generation and evolution of Sin- ogella races. It is suggested that under natural selection Ostracods have experienced such major development stages as having segmental appendage to mantle to chitin shell. The discovery of these fossils provides solid evidence for changing the former“Lantian flora”to “Lantian biota”. 看一下是否有斜体
