What does archaeology means?

Archaeology is the study of the past, particularly people, by looking at their material remains (skeletons, pottery, settlements etc).

It is not fossils, it involves humans. Before humans (hominins) is palaeoanthropology, and before that is palaeontology.

Archaeology is a sub topic of anthropology. Anthropology is the study of every aspect of humans, past-future. Archaeology mainly focuses on the past. It does in fact involve fossils. Because anthropologists believe in some sort of evolution, fossils of hominids, primates and any animal a hominid may have come in contact with (eaten) are studied. Archaeologists also study artifacts which is any human made object. Another spelling of archaeology is archeology, but that is a less used spelling...
