Where are all the dinosaurs?
While most people are introduced to paleontology through dinosaurs and pterodactyls, most paleontologists work with other creatures. Paleontology is the study of the history of life on earth. Just like there are biologists who work on bears, fish, trees and insects, there are also paleontologists studying the histories of each of these groups. Furthermore, paleontologists are often limited in what they can study based on what is preserved in the fossil record. Entire forests are rarely buried in mud. As a result, there are few squirrels to be studied in the fossil record. Sand dollars, on the other hand, spend most of their life in the mud. As a result, they have a much richer fossil record.
