Radioactive dating.
A paleontologist might use a geologic timescale clock, which shows the Earth's history in a chronological order based on rock layers and fossil records. This allows them to track the evolution and extinction of species over millions of years.
Geologists determine the age of rocks through a process called radiocarbon dating, a process which "peers inside [the] atoms" of the rocks. For more detailed information about how radiocarbon dating works, check out the related link which is a website with lab instructions for groups in a class.

Paleontologists use radiometric dating methods to determine the actual age of rocks. These methods involve measuring the decay of radioactive isotopes within the rocks to calculate how long they have been forming. By analyzing the ratio of parent isotopes to daughter isotopes, scientists can estimate the age of the rocks.

Ex: The paleontologist carefully brushed dust off of an ancient fossil.
