Question

Which of the following period is known as the age of fishes?
A. Ordovician period
B. Silurian period
C. Devonian period
D. Carboniferous period

Answer 1

Grill bearing aquatic craniate animals that do not possess limbs with digits are called fish. The age of fishes is related to the Paleozoic era. The Paleozoic era is considered as the earliest of the three geological eras. The above-listed options are the various periods of the Paleozoic era.

Complete answer: The term Paleozoic era means old life or ancient life. It is considered as the earliest of the three generations of the geological era. The Paleozoic era is divided into six geologic periods and is the longest era lasting from 541 to 251.902 million years ago. The Paleozoic era can be defined as a dramatic geological, evolutionary, and climatic change. The six geologic periods are Cambrian period, Ordovician period, Silurian period, Devonian period, Carboniferous period, and Permian period. The first period of the Paleozoic era is the Cambrian period. The Cambrian period is so named because of the event Cambrian explosion that took place which led to the evolution of the largest number of creatures in any single period in the history of the earth. Biological classes such as primitive fish, cephalopods, and coral evolved in the Ordovician period and are still prevalent today. The Silurian period is the one in which the mass evolution of fishes was seen. In this period numerous jawless fish were seen and also jaw fishes evolved. The Devonian period which is also referred to as “The Age of Fishes” shows huge diversification of fishes. average global temperatures were exceedingly high during the Carboniferous period. Permian is the last period and during this period all the continents fused together to form supercontinent Pangea.
So, option C is the correct option.

Note: After the Neoproterozoic era comes the Paleozoic era and is further followed by the Mesozoic era. The Earth's second mass extinction event took place near the end of the Devonian period in which 70% of all species became extinct in an event known as the late Devonian Extinction.
