摘要

The present study records the discovery of megaplant fossils from the middle part of the Ediacaran Jodhpur Sandstone, exposed in the mines around Sursagar area (GPS location 26 degrees 20'03 '' N; 72 degrees 59'72 '' E), Jodhpur, Rajasthan. This is the first record of the giant size noncarbonaceous plant fossils from the Precambrian sequences. The fossils show well-developed thallus, branching pattern, development of possible oogonia and zoospores, and antheridea. Showing morphological similarity with the extant Vaucheriacean plant, the thallus is about 140 times bigger in size. Preserved on the top of the bed, these are also associated with well-developed microbial mats. The same horizon has also yielded poorly preserved circular structures with medusoidal affinity which can be compared with the Aspidella sp.
