What does the principle of faunal succession state?

a. rock layers with the same unique grouping of fossils are of the same geologic age.

b. absolute dating is required to determine the relative age of animals based on their fossils.

c. specific groups of organisms have followed one another in a definite sequence through the earth's history.

d. fossils are deposited in approximately horizontal layers and spread out until they reach a barrier.

The principle of faunal succession state "Specific groups of organisms have followed one another in a definite sequence through the Earth's history."

Explanation:

Faunal succession basically means is that the fossils of the flora and fauna of different eras can be found in a specific order and never in the same strata. This allows the geologists to determine the time sequence and also to identify the various strata by dating the fossils that are found in each of them. The older version of fossils are found beneath the fossils of modified versions. For example fossils of simple feathers that cannot support flight are found to be succeeded by fossils of more complex feathers.
