贵州这个西南部欠发达省份,在人们的心目中也许或多或少与贫穷联系在一起。但对于科学家,特别是研究地球早期生命的古生物学家来说,贵州又是一个极为富有的宝地。二十多年前,古生物学家在贵州瓮安地区新元古代陡山沱组磷酸盐岩中发现了大量的微型球状化石,经过长期的研究,一系列改变人类对早期动物演化看法的成果呈现在世人的面前。贵州这片并不富饶的土地也就成了中外古生物学家争 Guizhou, an underdeveloped southwestern province, may be more or less associated with poverty in people’s minds. But for scientists, especially palaeontologists who study the Earth’s early life, Guizhou is another extremely rich place. Twenty years ago, paleontologists discovered a large number of microscopic spherical fossils in the Neoproterozoic Doushantousu phosphate rock in Weng’an, Guizhou Province. After a long period of research, a series of results that changed human’s views on the early evolution of animals were presented In the world This piece of land in Guizhou, which is not fertile, has also become a battle between Chinese and foreign paleontologists
