    Full Title: Earth’s oldest impact crater was just found in Australia – exactly where geologists hoped it would be

      We have discovered the oldest meteorite impact crater on Earth, in the very heart of the Pilbara region of Western Australia.
    
      The crater formed more than 3.5 billion years ago, making it the oldest known by more than a billion years.
    
      Our discovery is published today in Nature Communications.

    Shatter materials in situ covered by dateable layers so stratigraphically strong evidence.
