Question

Birds and mammals in geological development of earth rose in period
A. Permian
B. Carboniferous
C. Jurassic
D. Oligocene and Eocene

Answer 1

The dinosaurs and mammals emerged in the Mesozoic era (Jurassic period). The Jurassic period is also known as the Age of Reptiles.

Step by step answer:
In option A, Permian is suggested. The Permian period is the end of the Carboniferous period and the precedent of the Triassic period. It was a period of around 299 million years ago. This period saw a mass extinction of species believed to be caused by a highly perilous volcanic eruption. The continent of Pangea emerged. The climate was highly cold and dry.
In option B, Carboniferous period is mentioned. It was the Paleozoic era. It was preceded by the Devonian period. The main finding of this period is the presence of large swamps. As swamps produce coal, the period was named as Carboniferous.
In option C, Jurassic period is mentioned. It was a period of the Mesozoic era. The Jurassic period is widely known for its warm, wet climate that gave rise to lush vegetation and abundant life. Many new dinosaurs and birds emerged. Also, during this period, the continent Pangea split.
In option D, Oligocene and Eocene were the major transition period. This period saw a mass extinction of flora and fauna. The species which disappeared were aquatic in nature. The cause is suspected to be a meteor or asteroid hit.
So, the correct option is option C

Note: The Jurassic period lasted for 56 million years from the end of the Triassic Period and the beginning of the Cretaceous Period. The Jurassic period is also known as the Age of Reptiles. Marine life was extremely diversified. The period saw aerial, terrestrial, and marine dinosaurs.
