Paleontologists use carbon dating to determine the age of rocks.
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 fossils to determine the relative ages of rocks. Due to evolution the fossil assemblage in rocks changes over time and the different assemblages can therfore be used to place the rocks in which an assemblage is found in its place in the evolutionary sequence.

Paleontologists, stratigraphers, and geophysicists collaborated with geologists to develop the geologic time scale. Paleontologists studied fossils to identify and date rock layers, stratigraphers analyzed the layering and deposition of rocks, and geophysicists used techniques like radiometric dating to determine the age of rocks.
Stegosaurus fossils actually date to between 155 and 150 million years ago. Using various methods, paleontologists are able to determine the age of rocks. Then they know that fossils in those rocks are the same age as the rocks. In the case of Stegosaurus, they know the rocks are between 155 and 150 million years old, and they know the Stegosaurus fossils are the same age.
Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists studied fossil evidence, stratigraphers looked at the layers of rock formations, and geochronologists used radiometric dating techniques to determine the age of rocks and fossils.
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists study fossilized remains of ancient life forms, stratigraphers study rock layers and their relationships, and geochronologists use various dating techniques to determine the age of rocks and events in Earth's history.
