When did the Mesozoic Era occur?

The Mesozoic Era is a significant period in Earth's history that spans from approximately 245 million years ago to about 144 million years ago. This era is often referred to as the "Age of Reptiles" because it was dominated by dinosaurs and marked by the evolution of many reptiles and the first appearance of mammals and birds. It is crucial in understanding the geological and biological development of our planet, as it follows the Paleozoic Era and precedes the Cenozoic Era.

The timeline indicated in the correct answer encompasses the Triassic, Jurassic, and Cretaceous periods, which are pivotal for studying the evolution and extinction of various species, including the extensive range of dinosaurs. Understanding this timeframe is essential for grasping the larger context of both paleontology and Earth's geological history.
