The main fragment of meteorite NWA 11119, the oldest dated whole rock. One of the oldest Martian meteorites found on Earth, Allan Hills 84001 has been measured to have crystallized from molten rock 4.091 billion years ago.
The group takes its name from Mighei (Ukraine), but the most famous member is the extensively studied Murchison meteorite. Many falls of this type have been observed and CM chondrites are known to contain a rich mix of complex organic compounds such as amino-acids and purine/pyrimidine nucleobases.

The meteorite was a type called a carbonaceous chondrite that is rich in carbon and also contains phosphorus. Its diameter was approximately 23-36 miles (37-58 km), Drabon said, making it about 50 ...
The reason may be, at least partly, price. Toledano declined to disclose how much the fragment used for the B/1M cost, but he noted that raw meteorite can sell for more, per gram, than gold.
A giant meteorite first discovered in 2014 caused a tsunami bigger than any in known human history and may have sparked life, scientists reveal. A giant, ancient meteor four times the size of ...
In January 2020, astronomers reported that the oldest material on Earth found so far are Murchison meteorite particles that have been determined to be 7 billion years old, billions of years older than the 4.54 billion years age of the Earth itself.[5][6]
