Learning the most from the least

Not all fossils are large bones of things like dinosaurs or mammoths. Some of them are small enough to require a microscope in order to identify them. Called microfossils, these tiny fragments, and even remains of single-celled organisms, can tell us a good deal about things like the climate, the vegetation, the temperature, and chemical composition of the water and air when a given layer or strata of rock was laid down.

Here’s a link to an article about using microfossils to solve the mystery of what killed the last of the mammoths.
