Carbonaceous chondrites, or C chondrites, are a class of chondritic meteorites comprising at least 7 known groups and many ungrouped meteorites. They include some of the most primitive known meteorites and represent only a small proportion (4.6%) of meteorite falls. These are named after a prominent meteorite—often the first to be discovered—in the group. For CO3, the small town of Ornans (famous for the painter Gustave Courbet), in France (not far from my home in the French department Doubs!).

CO3 meteorite can contain organic compounds such as simple formic and acetic acid, to much complex as alpha-amino acid, adenine and guanine (the "G" and the "A" in the basic DNA code made of guanine (G), adenine (A), thymine (T), and cytosine (C))... all common in any lifeform! With an other small chondrules carbonaceous chondrite group, CO3 are sometimes considered as come from a comet.
