A team of researchers from University of Lucknow have found out a giant size fossil five kilometers from Jodhpur in Sursagar mines region, Rajasthan.

The discovery of the giant size fossil has opened a new window to understand evolution of life on earth. This is considered to be the largest non-carbonaceous plant fossil. It is around 140 times bigger than today's algae species. It has physical characteristics of Vaucheriacean plant. Vaucheriacean plant is a type of yellow-green algae found in fresh or marine water.

The research team has also addressed the media regarding their findings. According to one of the researcher, the plant fossils contain carbon and have simple structures. He has also said that it is rare to find fossils which are non-carbonaceous or lacking carbon contents.

These mega plant fossils imply a high possibility of presence of hydrocarbons in the Marwar Basin as the Vaucheriacean plants are known to reserve oil as food material. The fossils are visible in naked eye and are being kept under proper preservation. The researchers are expecting that the plant might be of 630-542 million years old.
