Most of the fossils are found under which type of rock?
Sedimentary rock
Metamorphic rock
Igneous rock
None of these
As we have learned in Evidence of Organic Evolution: Paleontological Evidence -
Fossils are the remains, traces and impression of past organisms found in rock of different ages and can be found in sedimentary rocks. Different-aged rock sediments contain fossils of different life-forms who probably died during the formation of the particular sediment.
Hence, the correct option is (a).
