Allan Hills 84001 ( ALH84001 [1]) is a fragment of a Martian meteorite that was found in the Allan Hills in Antarctica on December 27, 1984, by a team of American meteorite hunters from the ANSMET project. Like other members of the shergottite – nakhlite – chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars. The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.
