| Abstract: | he fossil coccoliths described here are found in the Lower Cambrian in Zhongyicun of Jinning County in Yunnan Province. Two new genera and four new species of discoasters have been identified. The new genus and species are listed as follows: Microtubcdiscoaster gen. nov., including M. kunyangensis gen. et sp. nov.,M. honeycomb gen. et sp. nov., Eotetralithus gen. nov., including E. gin4golabulatus gen. et sp. nov.; E. tubepillar gen. et sp. nov. These forms can be regarded as the oldest fossil coccoliths of all coccoliths that have been hither to reported in every country of world. |
