摘要
Helically coiled small spheroidal fossils like those described here were first discovered from the Ediacaran Doushantuo Formation of southern China. The present study shows however that these fossils are very different in structure and hence the authors reach different conclusions about their relationships. The original composition of the fossils unfortunately is masked by them having been phosphatised. However the plastic deformation suggests that the inner wall may have been composed of chitin or cellulose. Location Upper Doushantuo Formation, Weng’an, Guizhou.
