A 2-billion-year-old dark lump of rock that landed in Sahara desert is actually a new type of Martian meteorite, containing 10 times more water than usual.
This new class of meteorite was found in 2011 in the Sahara Desert. Designated Northwest Africa (NWA) 7034, and nicknamed Black
Beauty, it weighs approximately 320 grams.
US scientists determined the meteorite formed 2.1 billion years ago during the beginning of the most recent geologic period on Mars, known as the Amazonian.
