How Did the Paleozoic Era Influence the Mesozoic Era?
The Earth is billions of years old and has undergone countless changes over that time. While the Mesozoic era provided the perfect conditions for dinosaurs to rule over our planet, it wouldn’t have happened without the Paleozoic era. This period laid the foundation by shaping ecosystems, climate, and land masses over millions of years. Below, discover how the Paleozoic Era influenced the Mesozoic Era.
Environmental Changes
During the early Paleozoic era, specifically the Cambrian and Ordovician periods, the Earth was relatively warm with a tropical climate. Ice caps had yet to form in the polar regions, and shallow seas covered most of the planet. These differences in the environment allowed sea life to thrive and evolve in complex ways. Over millions of years, some invertebrates and plants made their way onto land and began evolving.
Continental Drift
Another way the Paleozoic Era influenced the Mesozoic Era was through continental drift. Earth’s tectonic plates were hard at work during the early formation of the planet. During the Cambrian and Ordovician periods, the supercontinent Gondwana formed and eventually broke apart into smaller continents. Then, during the middle of the period, these continents moved together again, and shallow seas once more covered the planet.
As tectonic plates moved, the continents continued to merge and pull apart, eventually forming Pangaea at the end of the Paleozoic era. By this point, the planet’s interior, encompassing the supercontinent, was incredibly dry due to its massive size, which had dried up some of the oceans.
Mass Extinction Events
During the Paleozoic era, nearly 96 percent of all marine species died, making it one of our planet’s largest mass extinction events. Species perished due to volcanic eruptions, warming ocean waters, climate shifts, and the natural release of methane gas.
This mass extinction was pivotal to the Mesozoic era because, if other animals had not died off, early dinosaurs would have faced more competition for food and territory, which could have caused dinos to die out.
The Rise of Reptiles
During the fifth interval of the Paleozoic era, specifically the Carboniferous period, reptiles began to evolve and diversify. Amniotes were among the first amphibian-like reptiles to emerge, and soon enough, species would diversify across the continent.
By the time the Mesozoic era began, the earliest dinosaurs were already emerging. However, we didn’t have well-known species like the T. rex until later in the Mesozoic era during the Cretaceous Period.
