On May 27, 2007, several dozen "UFO" shaped gangues were found in Shangrao County, Jiangxi Province. Experts indicate that the UFO gangues were formed about 300 million years ago.
The UFO gangues were found in an abandoned heap of gangues. There are several coal mines around the heap. Gangues are the abandoned materials left after the coal has been extracted from the rock. Among these UFO gangues, several of them have diameters over 4.9 feet and thicknesses between 7.9 inches and 23.6 inches. They weighed between 1764 pounds and 1 ton.
An engineer from the Shangrao Coal Bureau suggested that the ages of the UFO gangues are between the Paleozoic Late Carboniferous and Early Permian, so they're about 300 million years ago.
