The Mesozoic Era is commonly referred to as the Golden Age of Dinosaurs because it is the period during which dinosaurs were the dominant terrestrial vertebrates. This era lasted from approximately 252 to 66 million years ago and is divided into three key periods: the Triassic, Jurassic, and Cretaceous.

During the Mesozoic, a diverse range of dinosaur species evolved, adapted to various environments, and occupied different ecological niches. This era witnessed the rise of iconic dinosaur groups such as theropods, sauropods, and ornithischians, showcasing significant evolutionary advancements in size, form, and function. The climate of the Mesozoic was generally much warmer, and the continents were configured differently than today, allowing for rich biodiversity and the establishment of complex ecosystems. This abundance and diversity of dinosaurs, along with the unique ecological conditions of the time, solidify the Mesozoic Era's designation as the Golden Age of Dinosaurs.

In contrast, the Cenozoic Era, which follows the Mesozoic, is often referred to as the Age of Mammals, as mammals became the dominant land animals after the extinction of the dinosaurs. The Paleozoic Era, preceding the Mesozo
