Gujba is a bencubbinite (carbonaceous chondrite). According to the Meteoritical Bulletin (MB 85), Gujba was witnessed by the occupants of the village of Bogga Dingare, Nigeria, as it fell in a cornfield the evening of April 3rd, 1984. Because the villagers broke it into several pieces, the original mass of the meteorite is unknown but estimated to be approximately 100 kg.

Bencubbinites are unusual stony-iron meteorites composed of roughly equal amounts of Fe, Ni metal and ferromagnesian silicates. Gujba is classified as a bencubbinite (CBa); meteorites in the CBa group are primitive, metal-rich chondrites. The bencubbinites represent some of the most fascinating meteorites, recording evidence of violent planetary-sized impacts, and containing some of the most primitive solar system materials. Their primitive characteristics make the CBa chondrites valuable recorders of early nebular processes.

To date, Gujba is the only witnessed bencubbinite fall.
