摘要：

Last week, an extraordinary claim was published — that tiny fossil tunnels created by burrowing creatures about one billion years ago had been identified in rocks in central India. If true, this would double the time span of the animal fossil record. But apart from doubts over the interpretation of the structures as tunnels, the rocks may be only about half the age claimed.
