Q.The golden age of reptiles was a) Mesozoic era b) Cenozoic era c) Paleozoic era d) Proterozoic era

Anatomically modern humans arose and exist within the Quaternary period, the current and most recent period of geological time.

The geological time scale places the emergence and spread of the genus Homo, and specifically anatomically modern Homo sapiens (appearing roughly 200,000-300,000 years ago), within the Quaternary period, which is subdivided into the Pleistocene and the present Holocene epochs. Cambrian, Silurian and Cretaceous are much older periods (Cambrian and Silurian in the Palaeozoic era, over 400-540 million year …

The Mesozoic Era is called the Golden Age of Reptiles because dinosaurs and other reptiles dominated the Earth during this period.

Geological time is divided into eras based on major shifts in dominant life forms. The Mesozoic Era, spanning roughly 252 to 66 million years ago and comprising the Triassic, Jurassic and Cretaceous periods, saw reptiles (especially dinosaurs, along with marine reptiles like ichthyosaurs and flying reptiles like pterosaurs) become the dominant vertebrate group on land, sea and air, which is why it is called the 'Golden Age of Reptiles' or 'Age of Reptiles'. Option (a) the Paleozoic Era preceded this and was dominated by early fishes, amphibians and the rise of early reptiles, not their peak. Option (c) the Proteroz …
