    • Abstract:
      The article reports that the newly found fossils in Australia may belong to the Cryogenian period. Adam Maloof of Princeton University and his colleagues have reported that the fossils have been found from rocks between 635 million and 659 million years old. Maloof says simple forms of life, such as bacteria and algae with cell nuclei, lived during the Cryogenian.
