Feb 28, 2020 · Following the Mesozoic era was the Cenozoic, which began about 66 million years ago. This period is also known as the "Age of Mammals," as large mammals, following the extinction of the dinosaurs, became the dominant creatures on the planet. In the process, mammals diversified into the many species still present on the Earth today. The Mesozoic era is frequently known as the Age of the Dinosaurs or Age of Reptiles, but many other life forms evolved and thrived during this time, including marine invertebrates, flowering plants, birds, and mammals. The Mesozoic was also a time of major geologic change during which great thicknesses of rocks were deposited across the western US.1 / 11.

Mesozoic. ( geology) The Mesozoic era. The whole history of the earth is divided into five eras, with corresponding rock-systems. These are: 1. Archæan or Eozoic 1 era, embodied in the Laurentian system; 2. Palæozoic 2 era, embodied in the Palæozoic or Primary system; 3. Mesozoic 3 era, recorded in the Secondary system; 4.Mesozoic definition: Of, relating to, or being the era of geologic time from about 251 to 65 million years ago.
