摘要
Abundant cryptospore-like microfossils have been collected from a sample of the"Middle"Cambrian Log Cabin Member of the Pioche Shale in eastern Nevada,USA.Compared with organic-walled microfossils obtained from the Cambrian Kaili Formation in eastern Guizhou Province,China,some specimens of leiosphers may be inferred to be similar cryptospore-like microfossils.The new fossil record would be the oldest known specimens of cryptospore-like microfossils during the Cambrian Period.
