Paleontology is the branch of biology that studies forms of life
that existed in former geologic periods, chiefly by studying
fossils. Paleontologists use almost all the branches of science
to aid their quest to know more about Earth's early history.
They are constantly updating, adding to and even discarding
information. As new discoveries are made, palentologists must
often reexamine their own results: "Does this new discovery
agree with my own findings?" Paleontologists generally don't
make lots of money. Their reward is the joy of exploration and
discovery. They love to share and compare their ideas and
discoveries with other scientists and especially, us!
