What else can I help you with?
What fossils are helpful to geologist because they reveal the relative ages of the rock layers in which they occur?
Those types of fossils are called index fossils.
Who was the geologist that discovers the same fossils in different parts of the world?
Edward Suess
How would a geologist determine the age of rock layers and fossils if the geologist found a never before seen rock layer that contain fossils?
First step would be relative-dating: examining the new unit in the context of known rocks above and below it. Then look for correlative formations & fossils elsewhere.
What kind of scientist examines rocks to learn about earth's history and structure?
geologist
When were the fossils found?
Do you mean the first time? Fossils have been found for a long time. Even you can find one anytime at specific locations. Ask a geologist.

to date a rock layer and other fossils within that layer

What is one radioactive isotope the geologist can use to learn exact age of the rock?
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
What is a scientist called who studies rocks and fossils?
Strictly speaking these are two differing types of scientists. Petrologists study rocks and paleontologists study fossils. However both these disciplines are covered in the broader training of a geologist.
I found a fossil and don't know what it is?
It is best to consult a geologist or archaeologist to help you identify unknown fossils.
What can a scientist learn from fossils?
They can learn about evolution, as many living fossils have changed quite a bit over time.
