What layer is an old fossil found?
fossils are formed in Sedimentary rock
What type of rock layer are tertiary fossils usually found in?
metamorphic
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.
If the same types of fossils are found in two separate rock layer's it's likely that the two rock layers?
If the same types of fossils are found in two separate rock layers, it's likely that the two rock layers ____.
Which type of dating uses index fossils?
Relative dating. Paleostratigraphy correlates layers of rock using index fossils found within them.
How can fossills be used to determine the relative ages of rock layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
Can fossils be used to determine the relative ages of rocks layers?

Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
How can you use fossils and geologic-features interpret the relative age of rock layer?
Geologists use carbon-14 to interpret the relative age of rock layers
What layer is an old fossil found?

What type of rock layer are tertiary fossils usually found in?
metamorphic
Which example describes method of relative dating?
using fossils to determine the oldest rock layer in a canyon
What layer of soil was dinosaur bones found in?
Fossils are not found in the soil. They are found in layers of rock after time.
