What is the Mesozoic Era commonly known as?

The Mesozoic Era is commonly known as the Age of Reptiles primarily due to the dominance of reptiles, particularly dinosaurs, during this extensive period in Earth's history, which lasted from about 252 to 66 million years ago. This era is characterized by significant geological and biological developments, with reptiles evolving into a wide variety of forms and sizes. The Mesozoic is divided into three major periods: the Triassic, Jurassic, and Cretaceous, each marked by further diversification and evolution of reptilian species.

This understanding highlights the prominence of reptiles not only in terms of diversity but also in terms of ecological dominance during the Mesozoic. The fossil record provides an extensive array of evidence illustrating this reign of reptiles over terrestrial ecosystems, making the characterization of this era as the Age of Reptiles particularly apt.
