What do you think a Paleontologist is? A paleontologist is a scientist who studies paleontology, learning about the forms of life that existed in former geologic periods, mainly by studying fossils.
Fossils Fossils are the reason we have most of this information. For almost 200 years, paleontologists have been discovering fossils all over the world. They’ve identified more than 330 different kinds of dinosaur fossils, and find new fossils every year! These fossils can tell us how big an animal grew, what it ate, and even how it died.
