Tatahounie is classified as a stone, achondrite, Diogenite (ADIO) Ca-poor. This rare meteorite fell on June 27, 1931 at 0130 hours about 2 1/2 mi. NE of the village of Foum Tatahouine, Tunisia. This rare Diogenite broke into thousands of small fragments, most no larger than a gram. The large mass broke up near the earth's surface and as a result fusion crust is virtually absent, making this a difficult meteorite to recognize. If it had not been witnessed, it most likely would never have been found. About 12 kilograms were originally recovered most of which was send to the Museum National d'Histoire Naturelle in Paris. Tatahouine has a cumulate texture with exceptionally large crystals, many reaching 2 cm long. In 1994, Dr. Alain Carion recovered a number of additional specimens raising the total weight recovered to about 13.5 kg. Tatahouine is one of a few meteorites that is only available in small sizes, most are under 1 gram, and as a result larger pieces are more expensive per gram than smaller pieces.
Pieces with crust on them are extremely rare. Even more rare are individuals. Pieces that are ablation smoothed on all sides with some bits of crust remaining. After searching kilograms of material I have found only a few and those are always very small 1 gram or less.
