What Do Paleontologists Do

Paleontologists are scientists who study fossils—the remains or traces of organisms that lived long ago. These scientists help us understand what life was like millions of years ago. They search for fossils in rock layers, which are different levels of rock stacked on top of each other like the layers of a cake.

When paleontologists find fossils, they use special tools like small brushes and picks to carefully dig them out. This is important because fossils can break easily. After they remove the fossils, they bring them to labs where they can study them more closely. Paleontologists often piece together fossil bones like a puzzle to figure out what an animal looked like when it was alive.

Paleontologists also compare fossils from different rock layers. Older rock layers are usually found deeper underground, while younger layers are closer to the surface. By studying fossils in these different layers, scientists can see how life changed over time. They also examine the rocks around the fossils to learn about the environment where the organism lived. For example, if they find ocean animal fossils in rocks far from the sea, they know that area was once covered by water.

Interesting Fact: The largest dinosaur fossil ever found was a Patagotitan mayorum in Argentina. This dinosaur was as long as three school buses and weighed as much as 10 elephants!
