"They are our oldest ancestors ," Dr. Noffke told the Geological Society conference.
Unlike dinosaur bones, newly discovered fossils are not parts of the body. They are textures on the sandstone surface, which have been engraved by living creatures a few billion years ago.
The ancient Pilbara region, in the north of Western Australia, used to be coastal strips, and the rock accreted by sediments billions of years ago was in an open state, allowing scientists to conduct research. save, according to a report published in Nature Geoscience.
The new report opens up hope for an attempt to find ancient life on other planets like Mars. Most likely the ruins of life lie somewhere on the surface of the red planet waiting for people to discover.
