The Mesozoic era lasted from 251 mya to 65.5 mya. It is divided into three periods: the Triassic, the Jurassic, and the Cretaceous. Pangaea broke apart during the Mesozoic era. It began to break apart in the Late Triassic. Eventually, Pangaea split into two separate landmasses-Gondwanaland and Laurasia. The Paleozoic Era ended with the largest extinction event of the Phanerozoic Eon, the Permian–Triassic extinction event. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover.

The Mesozoic Era began approximately 251 million years ago (mya) at the end of the Paleozoic Era when the area that would eventually be the Colorado Plateau broke free from Pangea, the supercontinent.

Over 90 percent of many species of plants and animals were wiped out in this mass extinction event; the Permian extinction is also called “the Great Dying” because it is the most significant extinction event in history.Cenozoic (66 million years ago until today) means ‘recent life.’ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era. Cenozoic signposts are colored yellow.
