Acritarch: Definition, Selected genera & Classification

Acritarchs (from Greek achritos 'uncertain' and arché 'origin') are organic microfossils, known from the Archean eon of the Precambrian to the present. The classification is a catch all term used to refer to any organic microfossils that cannot be assigned to other groups. Their diversity reflects major ecological events such as the appearance of…
