What might an archaeologist learn from ancient bones? what other artifacts would an archeologist study?

History of the earth. Like how continents used to be together (Pangea) or dinosaurs. Archeologists may also study rocks.

Some things that archaeologists can learn from ancient bones: They can learn what era it came from, what it lived through, things it could have encountered, how the weather was there (maybe it traveled from near the oceans and somehow got itself far into the desert), & how it may have survived also closely related animals to it. Other artifacts they can study can be like ancient bowls, plates, or perhaps spoons made of wood, & it can also be many other things. Hope this helps!
