Abstract: | Carposporangium- and spermatangium-like reproductive structures associated with differentiated vegetative tissues have been observed in the multicellular rhodophyte fossils, which were well preserved in the 650-Ma-old phosphate rocks of Doushantuo Formation in Guizhou Province, South China. The fossils show details of cellular structures that are comparable to the female and male reproductive organs of some extant rhodophytes. The first fossil-histological evidence for sexuality of Precambrian non-vascular plants is provided. |
