Detailed explanation-1: -The Mesozoic era spans from about 252 million years ago to 66 million years ago. It is also called the age of reptiles or the age of dinosaurs. In the Mesozoic era, the animals that existed ranged from Tyrannosaurus Rex to birds and mammals.

Detailed explanation-2: -Mesozoic (252-66 million years ago) means ‘middle life’ and this is the time of the dinosaurs. This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you.

Detailed explanation-3: -The Mesozoic era saw the rise of some of the most iconic animals, from Tyrannosaurus rex to birds and mammals. During the Mesozoic, or “Middle Life” era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth.

Detailed explanation-4: -Among the various clades of mammals in the Mesozoic are early monotremes and stem-members of the two therian groups. Metatheria is the total-group for Marsupialia, and is known from the Early Cretaceous onward. Eutheria, the total-group for Placentalia, goes all the way back to the earliest Late Jurassic.

Detailed explanation-5: -From the dawn of the dinosaurs to their extinction, the Mesozoic was ruled by reptiles. Dinosaurs may have dominated this era, but it also saw the evolution of mammals, birds and flowering plants.
