摘要

The affinity of phosphatized globular fossils, one of the important types in the Ediacaran Weng’an biota, was first interpreted as that of green algae. Some new data of phosphatized globular fossils from Weng’an biota are reported in this paper, including globular fossils with budding structure and transitional forms between Parapandorina and Megaclonophycus. These new data suggest that some characteristics of globular fossils cannot be interpreted by metazoan resting eggs and embryos, though the interpretation of globular fossils from Ediacaran Weng’an biota as embryos is the best hypothesis at present.
