Early Fossil Record and Evolution of Echinoderms and Octocorals - evidences from the Yangtze Platform, China
Final Report Abstract
As for other Metazoan groups, the Cambrian time represents a crucial period in the evolution of nearly all organism groups, and the Echinodermata and Octocorallia are no exception. Echinoderms made their first unequivocal appearance in the fossil record ("Cambrian Stage 3") and underwent a rapid diversification, establishing a few major important Palaeozoic echinoderm groups. The first appearance of undisputed echinoderms after the Terreneuvian ("Cambrian Stages 1-2") can be verified after our investigations due to the fact, that all investigated late Neoproterozoic and Terreneuvian samples from the Yangtze Platform (eastern Gondwana) during this project lacking echinoderm ossicles. The same applies to octocoral remains. Therefore, future research and investigations concerning these organism groups should primarily focus on the slightly younger strata ("Cambrian Stage 3" onwards) where probably a greater potential capacity can be found.
