How does determining the ages of igneous rocks help to date fossils?
Determining the ages of igneous rocks helps to establish the age of the rock layer in which fossils are found. By dating the igneous rocks above and below the fossil-containing layer, scientists can narrow down the possible age range of the fossils found within that layer. This helps to provide a more accurate estimate of the fossil's age.
What group are fossils never found in?
Fossils are never found in Igneous rocks
How can the geologist determine the age of the fossil if the geologist finds a fossil in a layer of sedimentary rock that lies in between 2 igneous extrusions?
The geologist will most likely take samples of the two lavas forming the igneous intrusions and use radiometric dating techniques to find their ages. He then would know that the age of the sedimentary rock was somewhere between the two. He may also look for (index) fossils within the sedimentary rock which may also give him an indication of the age of the sediment.
Are fossils found in sedimentary and metamorphic rocks?
