Mesozoic Era, Second of the Earth’s three major geologic eras and the interval during which the continental landmasses as known today were separated from the supercontinents Laurasia and Gondwana by continental drift. It lasted from c. 251 to c. 65.5 million years ago and includes the Triassic, Jurassic, and Cretaceous periods.The Paleozoic Era (544–245 million years ago) started with an explosion of new kinds of organisms. Major evolutionary events during this era included the first appearance of invertebrates, fish, amphibians, and reptiles. Plants also colonized the land, and vascular plants and seed plants evolved. The era ended with the Permian mass extinction.Earth's crust formed. D. Earth's poles flipped. Correct Answer. B. Earth's Environment became more stable. Explanation. During the early Paleozoic era, Earth's environment became more stable. This stability allowed for the diversification of life forms as organisms were able to adapt and evolve in a consistent and predictable environment.
