What types of rock were in the 4 major eras of earth?

The four major eras of Earth—Precambrian, Paleozoic, Mesozoic, and Cenozoic—are characterized by different types of rock formations. In the Precambrian era, metamorphic and igneous rocks dominate, reflecting the planet's early geological activity. The Paleozoic era features a variety of sedimentary rocks, formed from ancient marine environments and terrestrial ecosystems. The Mesozoic is known for its limestone and sandstone deposits, while the Cenozoic era showcases sedimentary rocks due to extensive erosion and sedimentation processes associated with the rise of mammals and flowering plants.
