The Smithsonian compromised and labeled it as seen in this photo. Irwin complained again and, eventually, both names were removed in favor of 'The Tucson Ring Meteorite' by which name it is known today. As far as I am concerned, it is the finest meteorite that ever fell. Much more ordinary is this 89g. Falling in Namibia in Pre-historic times, Gibeon irons are the most commonly available of all meteorites.
Many tons exist.
The strewn field over which pieces fell covers hundreds of square miles and new pieces are still being found. The parent body broke up high in the atmosphere and produced a wide variety of sizes and shapes. Most show smooth indentions known as 'thumbprints' or 'regmaglypts'. These make the pattern of swirling air that melted the surface of the meteorite as it entered the atmosphere. Gibeon meteorites are so common that the material is commonly crafted into trinkets of various types.
