Mayo Belwa is an aubrite (achondrite) that fell August 3, 1974, in the Adamawa district of Nigeria.
According to the Meteoritical Bulletin (MB 55):
A fireball was seen by herdsmen and sounds were heard over an area extending to 25 km from the impact site. The stone was sent to the Geological Survey of Nigeria and smelt strongly of sulphur when first received.
Over 10 lb (4.8 kg) of the Mayo Belwa achondrite were recovered.
