Detailed explanation-1: -Fossils are most likely to be found in sedimentary rock.
Detailed explanation-2: -Using the principle of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the two species must have existed during the same period of time (Figure 4). If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time.
Detailed explanation-3: -The Cenozoic Era (66 million years ago through today) is the “Age of Mammals.” Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age fossils like wooly mammoths.
Detailed explanation-4: -Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks.
