The rocks of the Doushantuo Formation, in China's Guizhou Province, are sprinkled with tiny, ancient fossils. They are no more than a millimeter in length. The 600-million-year-old organisms are preserved with such detail that the fossils, when freed from the rock in a chemical bath and scanned with X-rays, reveal not only individual cells but possible cell nuclei. Some fossils are jagged and round, like wizened Koosh balls. Other orbs, among the most intriguing specimens, are split by Y-shaped seams.
