Really old craters like the Yarrabubba crater in Western Australia are rare because Earths surface is constantly being reshaped by plate tectonics and erosion. "[The] crater was made right at the end of what's commonly referred to as the early Snowball Earth, a time when the atmosphere and oceans were evolving and becoming more oxygenated and when rocks deposited on many continents recorded glacial conditions," says earth and planetary scientist Chris Kirkland from Curtin University.
