The Phanerozoic is divided into three eras – the Paleozoic, the Mesozoic and the Cenozoic. Most of the evolution of multicellular life occurred during this time period.At the beginning of the Mesozoic Era during the Triassic, the ocean’s reefs were hard hit by the Permian extinction. It took millions of years for new, diverse seafloor ecosystems to evolve. By the time of the Jurassic, the seafloor was again thriving, but the reef's composition was different than the reefs we think of today.
