I did not realize that archaeology was separate from palaeontology.  I kinda thought they were the same.
How are the two different?
Well, I think it mainly has to do with the fact that palaeontologists only look at fossils.
OK, are fossils very common?
I'm not really sure, but it sure does seem to include a lot of stuff, even petrified wood and oil.
I guess anything organic could become a fossil?
I guess, archaeology is much more about the study of human activity by looking at materials that are found.
That is how the pyramids were uncovered.
