Mesosiderite, Found in Australia, 1921
If you know a thing or two about meteorites, you probably know that the ones with wacky names usually come from Australia. One such space rock, Dalgaranga, was found in 1921 after the discovery of the impact crater by an Aboriginal stockman in the same year. The Dalgaranga crater is of note as its one of Australia’s smallest impact craters and the only crater known to have been formed by a rare mesosiderite. Harvey H. Nininger, considered by many to be the father of contemporary meteoritics, was the first to recognize the Dalgaranga meteorite as a mesosiderite. The crater is believed to be approximately 270,000 years old, making Dalgaranga one of Earth’s oldest meteorites. Specimens are weathered, but still adhere strongly to a good magnet.
