Paleontology - Paleontology is a bit of a generic term at this point, meaning the study of fossil remains, but you can narrow it down slightly. Generally, paleontologists are people who actively excavate fossils as part of their job. Generally this requires a decent amount of training in geology and biology. They tend to use more of their geo background in the recovery, and bio background in identification and discrimination of species in the fossil record. These folks may find new species and name them, etc. When they're "done," the fossils they recover are curated into museum collections for others to study.

Paleobiology - Paleobiology is really more limited to the study of the biology of extinct animals, and they tend to study specimens in museums more so than excavate them (though not exclusively of course). This may be done through reverse engineering the animals' bones in order to calculate what they were capable of doing when alive, or analyses of interactions between animals ...more
