Smith and Cuvier discovered that similar groups of fossils in distant rock layers could be correlated. Why was this such a major breakthrough in geology?
AIt disproved the principle of superposition.
BIt proved igneous rocks held more information than sedimentary rocks.
CFossils could now be used to identify rock layers.
DFossils were no longer needed to study the history of Earth.
