Answer: False.
Step-by-step explanation:
The Mesozoic Era, also referred as "Middle Life", is an interval of geological time from about 250 to 65 million years ago. During that Era, life diversified rapidly and dinosaurs roamed the Earth. So this period is also known as the age of reptiles and of dinosaurs. This Era is one of three geologic eras of the Phanerozoic Eon, preceded by the Paleozoic, also known as ancient life. And it is succeeded by the Cenozoic, also known as new life.
