Archaeologists use fossils to scan the way of living of the past people.

Archaeologists dig up fossils!
People that study artefacts are called archaeologists. However people who study fossils are known as palaeontologists.
Artifacts are important to Historians (and Archaeologists) because they are actual evidence of past human activity. However fossils are NOT important to historians as they are too old, they ARE important to Geologists.
Because they tell them what sort of animals where around at the time.
because that is their job
In general, archaeologists do not sell the artifacts they discover. They consider this "treasure hunting" and not a proper academic practice. In addition, ancient artifacts are increasingly claimed as government property in their country of origin, so the discoverer has no legal right to sell them. When exploring such sites, archaeologists are typically working on a government sponsored project run by a museum or University. They are essentially selling their time and expertise. Even in situations where artifacts are not claimed by the government, legitimate archaeologists work to ensure that all important artifacts are given to Universities and/or Museums that will further research the artifacts and make them available for public display. (Think of Indiana Jones, who was sponsored by his University and gave them his "finds." Contrast this with his rival, Belloc, who was strictly after the money.) Note that fossils - such as dinosaur fossils - are the province of Paleontologists rather than Archaeologists. Fossils are generally treated like minerals such as gold; if you own the property, the material you find there belongs to you. Governments typically do not interfere with this because fossils and minerals have no cultural significance.
They dig for fossils or artifacts to figure out what early humans used for tools or their culture or how the shape of their bones were
The biggest problem with finding fossils in Antarctica is that everything is covered in ice, making it hard for archaeologists to excavate and find fossils.
How do archaeologists date fossils ? archaeologist can date fossills by seeingf how deep down it is in the ground [ checking how many layers ] , scientists can use radio-active dating, and compare a fossil that they know the exact date that it was from compare the looks and tell by that
To learn about the past.
so you can get oil and find out how did ancient people lived
