They were some of the largest animals to ever roam the planet, with some species growing to be as tall as a two-story building. Dinosaurs first appeared during the Mesozoic Era, which is sometimes referred to as the "Age of Reptiles." This era lasted from about 252 million years ago to 66 million years ago and was divided into three periods: the Triassic, Jurassic, and Cretaceous periods. During the Triassic period, the earliest dinosaurs evolved from smaller reptiles. These early dinosaurs were not very large, and they were not the dominant animals on Earth at the time. However, during the Jurassic and Cretaceous periods, dinosaurs became much larger and more diverse.
