“Jonathan Warnock/Indiana University of Pennsylvania, CC BY-ND Paleontologists look at tiny microfossils from organisms such as diatoms , radiolaria and dinocysts that are found in the sediment cores. Then they can match up the species they spot in the samples with the timeframes they were known to exist. For instance, a paleontologist might know from previous research that a particular species of diatom lived between 1.8 and 2.6 million years ago. ”
