Paleontology. You can't dig up the same fossil twice. But you're not going to claim that the study of ancient species using the fossil record is unscientific, I hope. Paleontology is very similar to archaeology, but because humans aren't the object of study, it's less affected by politics, and I haven't heard of any fights within paleontology over whether to call the field a "science."
