Question

Mesozoic era is known as golden age of
a. Fishes
b. Amphibians
c. Reptiles
d. Molluscs

Answer 1

Hint: Mesozoic Era, second of Earth’s three most important geologic eras of Phanerozoic time. Its name is obtained from the Greek term for “middle life.” The Mesozoic Era started 252.2 million years ago, following the termination of the Paleozoic Era, and ended 66 million years ago, at the starting of the Cenozoic Era.

Complete answer:
In the middle of the Mesozoic Era, life widened quickly and mammoth reptiles, dinosaurs, and different immense creatures wandered the Earth. Mesozoic era is considered as the golden age of reptiles as reptiles became prevailing during this period which persists from about 252 million years ago to about 66 million years ago.

The chief divisions of the Reptiles are, from oldest to latest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of main plant and animal groups that survive today first appeared during the Mesozoic, but this era is best considered as the time of the dinosaurs.

The earliest amphibian observed in Late Devonian rocks of Scotland dating to around 368 million years ago. The later Paleozoic saw a great multiplicity of amphibians, ranging from small legless swimming forms. The Devonian, part of the Paleozoic era, is also known as the Age of Fishes. Good evidence subsists for the emergence of mollusks in the Cambrian period.

Hence, the correct answer is option (C).

Note: Earth’s climate during the Mesozoic Era was usually warm, and there was little difference in temperature among equatorial and polar latitudes than there is nowadays. The geologic and biological transition happened in the Mesozoic era. During this era, the continents began to move into their present-day patterns. A different modernization of life-forms happened, partly because of the end of many former types of organisms.
