... first living organisms on Earth, and they can be preserved in Archean silica-rich rocks. One such outcrop from western Australia, dated to 3.5 billion years ago, may hold the oldest "microfossils."
... in conjunction with colleagues at the University of Colorado at Boulder will analyze plant microfossils in sediment samples collected from a variety of locations, including areas where streams expose ...

Phytoliths are another type of plant microfossil that is preserved for thousands of years and can be used to distinguish domesticated from wild maize. ...
... . The dating of these shorelines is confirmed by the presence of distinct conodonts – a microfossil in which the passing of time is recorded by rapid evolutionary changes.
"These trace fossils ...

The concentrations of microfossils and the composition of their shells can provide much information about the conditions of life thousands or even millions of years ago.
