<span>1. Fossils can help date rock horizons and can help identify similar environments when the same fossil is found in different locations;
2. Fossils helped identify how the different land masses moved/plate tectonics worked because similar fossils on different continents sometimes showed how the different land masses were once connected (e.g. Africa and South America);
3. Fossils can show how different species evolved over time.</span>
The process scientists use is simple: dig, brush, repeat. Fossils can be found in areas that once had living organisms, like lakesides and lake bottoms. To protect them they use a chemical coating. Hope I helped :D
You have different opinions, experiences, and so forth. Nobody is the same so you would have different ideas which can lead to a very creative outlook on things.
